HobbyPlus CR18P EVO V2 Rock Van Upgrade Guide — Drivetrain, Suspension, Steering and Body Parts

HobbyPlus CR18P EVO V2 Rock Van blue 1/18 RC crawler with roof rack and LED light bar

The HobbyPlus CR18P EVO V2 Rock Van already arrives with an unusually complete mechanical package for a compact 1/18 crawler, including portal axles, metal drivetrain gears, servo-on-axle steering, big-bore oil-filled shocks and a two-speed transmission. Its real long-term strength, however, is the number of Rock Van and CR18P parts available for maintenance, tuning and further customisation.

This guide looks beyond the RTR specification and focuses on what can actually be changed, repaired or developed as the Rock Van accumulates trail time.

Start with What the EVO V2 Already Has

The first rule with the Rock Van EVO V2 is not to upgrade parts simply because alternatives exist.

HobbyPlus already gives this version a relatively developed crawler chassis.

Its standard specification includes:

full-lock 4WD
two-speed transmission
full metal gear drivetrain
portal axles
heavy-duty driveshafts
servo-on-axle steering
threaded big-bore oil-filled shocks
5-degree kick-up aluminium chassis
60mm super-soft Mudder tyres
Deep Star internal beadlock wheels
180 55-turn brushed motor
FlySky ESC/receiver combination
7.4V 2S 600mAh LiPo battery
LED lighting

The chassis measures approximately 279mm long and 138mm wide, with a 160mm wheelbase. That short wheelbase is part of the vehicle's identity and should be kept in mind when changing suspension, tyres or weight distribution.

In other words, this is not a crawler that needs to be “fixed” immediately after purchase.

Rock Van Upgrade Strategy — Improve a Limitation, Not a Specification Sheet

The best upgrade path begins with an observation.

Where does your Rock Van actually struggle?

If the tyres lose grip, look at the tyre setup. If the chassis becomes unsettled over repeated bumps, investigate suspension tuning. If steering develops play, inspect links, bearings, hubs and CVDs. If drivetrain components wear after extensive use, replace or reinforce the affected area.

This sounds obvious, but it prevents one of the most common crawler-building mistakes: replacing a balanced factory setup with a collection of expensive parts that were never solving a problem.

Drivetrain — Already Strong, but Highly Serviceable

The EVO V2 uses an all-metal gear drivetrain as standard, so there is no reason to replace its complete transmission simply because alternative metal gears are available.

Instead, the strength of the parts catalogue is that individual drivetrain areas can be maintained or changed later.

Helical Pinion and Ring Gears

FairRC lists machined heavy-duty helical pinion and ring gear combinations among the Rock Van's related components.

The 11T/28T machined helical pinion and ring gear is one available configuration.

Because different gear combinations can affect drivetrain behaviour, this is an area where the specific intended setup matters more than simply choosing whichever gear set appears strongest.

Steel U-Joint Driveshafts

HobbyPlus already specifies heavy-duty driveshafts on the EVO V2, while FairRC also lists the steel U-joint driveshaft set for CR18P EVO and EVO V2.

That makes driveshaft support useful both for maintenance and for heavily used builds.

A replacement drivetrain part is often more valuable than a cosmetic upgrade if the crawler is being driven regularly rather than simply displayed.

Transmission and Gearbox Components

The Rock Van's two-speed transmission is one of the features worth preserving.

It allows a slower ratio for controlled crawling and a faster range for trail movement.

FairRC lists individual transmission gears, gearbox components, shift hardware and related parts for CR18P applications.

This means wear in one part of the mechanism does not necessarily require replacing an entire crawler or even the complete drivetrain.

Portal Axles — Preserve the Geometry Before Adding Weight

The Rock Van uses portal axles to increase clearance at the wheel ends.

This is a major part of its technical-crawler character.

The parts ecosystem includes axle housings, CVDs, portal hubs, stub axles, gear sets and machined axle components.

If steering develops looseness or drivetrain play, these parts should be inspected as a system rather than automatically replacing the complete axle.

The CR18P front CVD drive shaft, for example, is a useful service component to know exists before one is actually needed.

Brass Weight — Useful, but the Rock Van Does Not Need to Become Heavy

Low-mounted mass can improve stability, particularly on steep climbs and side slopes.

FairRC offers optional CR18P brass wheel weights and other brass components within the platform ecosystem.

That does not mean every available brass part should be installed together.

More rotating weight increases the work performed by the motor, drivetrain and steering system.

The Rock Van's short wheelbase and compact dimensions make weight placement particularly relevant. The objective should be a stable crawler that remains responsive, not simply the heaviest possible build.

Suspension — Tune the Big-Bore Shocks Before Replacing Them

The EVO V2 already uses threaded, oil-filled big-bore shocks.

That is important because it means the first suspension “upgrade” may simply be tuning what is already installed.

Preload, spring behaviour, damping and vehicle weight all interact.

FairRC nevertheless lists a complete aluminium big-bore oil shock option within the CR18P parts ecosystem.

A shock change makes most sense when it solves an actual problem such as inconsistent damping, wear or a build whose total mass has moved well beyond the original setup.

Links and Chassis Geometry

Links control where the axles sit relative to the chassis and influence how the suspension moves through its travel.

High-clearance links are attractive because their shape can improve clearance beneath the truck, but they should not be treated as an isolated cosmetic change.

Check wheelbase, axle angle, shock movement and driveshaft behaviour after changing link geometry.

The Rock Van works partly because its 160mm wheelbase creates a compact, manoeuvrable crawler. An upgrade should preserve the characteristics you actually like about the platform.

Servo-on-Axle Steering

The EVO V2's servo-on-axle architecture places the steering servo directly on the axle.

This creates a relatively direct steering arrangement and also places that component low in the vehicle.

FairRC carries an aluminium SOA conversion set among its CR18P components.

There are also steering links, ball studs, portal hardware and axle parts that can be serviced independently.

If the crawler starts to develop steering play, diagnose the source before replacing the servo itself. Links, bushings, hubs, CVDs and mounting hardware can all contribute to imprecise steering.

Bearings — An Upgrade You Usually Notice After the Original Ones Wear

Bearings are not visually dramatic, but they directly affect rotating assemblies throughout the crawler.

The CR18P EVO complete rubber-sealed bearing set provides a useful maintenance route for compatible builds.

A crawler used around dirt, sand or damp terrain will eventually benefit more from maintaining bearings and shafts than from adding another decorative component.

Tyres — Test the Standard Mudders First

The standard EVO V2 is already supplied with soft 60mm Mudder tyres paired with Deep Star beadlock wheels.

That means tyre replacement should be based on terrain rather than assumption.

The same basic 1.2-inch 60mm Mudder tyre also appears in the FairRC parts catalogue.

Before changing tyre size or tread, evaluate the existing setup on the surfaces you actually drive.

Different terrain may favour different tread characteristics, while larger tyres can affect steering clearance, effective gearing and body contact.

Wheels and Rotating Mass

Beadlock wheels make tyre experimentation easier because the tyre is mechanically retained rather than permanently glued.

This is particularly useful for a crawler that may evolve over time.

Changing wheel material, offset or weight can alter steering feel and stability, so wheels should be considered part of the suspension and drivetrain setup rather than purely a styling decision.

LCG Chassis Options

FairRC also lists a CR18P 2024 aluminium LCG chassis within the wider CR18P parts catalogue.

LCG — low centre of gravity — builds aim to keep significant mass lower in the vehicle to improve stability.

This is a more fundamental modification than changing tyres or adding a brass component.

Because this chassis is identified specifically as a CR18P 2024 component, compatibility with a particular Rock Van EVO V2 configuration should be verified before purchase rather than assumed from the CR18P name alone.

The Rock Van Body Is Part of Its Appeal

The body is what separates the Rock Van visually from almost every conventional crawler.

Its retro van form, enlarged wheel openings and trail equipment give it a distinctive shape without relying on a familiar pickup or SUV shell.

FairRC sells complete finished replacement bodies, including the finished Rock Van V2 polycarbonate body, alongside smaller body components.

That makes body damage less terminal and also opens another possibility: keeping one chassis while changing or refreshing the body later.

Lighting and Scale Equipment

The EVO V2's visual identity includes more than its shell.

FairRC lists model-specific components such as the Rock Van EVO V2 LED light set and Rock Van EVO V2 roof light bar.

These are useful both as replacement parts and for restoring a used vehicle whose scale accessories have been damaged.

Other Rock Van-specific parts include body hardware, grille and bumper components, roof equipment and vehicle screw sets.

Stock Rock Van or FairRC Mod?

There is another route if you like the CR18P platform but want a build that begins further along the modification path.

FairRC also uses the EVO V2 Rock Van as a basis for its own Mod RTR versions.

Those builds can add BATRAZZI tyres, Steelie beadlock wheels, brass wheel weights, winch equipment and FairRC-specific visual treatments.

The decision is therefore similar to other FairRC platforms: buy a standard HobbyPlus vehicle and choose every stage yourself, or start with a FairRC Mod that already incorporates part of the upgrade path.

What Should You Keep as Spare Parts?

If the Rock Van is used regularly rather than kept primarily for display, a small number of service parts are worth knowing about in advance.

Potential wear areas include:

CVD and axle components
driveshaft hardware
bearings
transmission and axle gears
steering links and ball studs
body mounting hardware
lighting components
vehicle screws and small pins

This does not mean buying every spare before it is needed. It means understanding that the Rock Van has parts support available when regular use eventually creates wear.

A Practical Rock Van Upgrade Order

I would approach the EVO V2 in this order.

Drive it stock. The standard specification is already unusually complete.
Evaluate tyres on your terrain. Do not change the Mudders without first understanding where they work and where they do not.
Tune suspension. Use preload and damping before assuming different shocks are necessary.
Inspect steering and drivetrain play. Bearings, CVDs, links and hubs deserve attention before adding power or weight.
Add low weight selectively. Use brass only where additional stability is actually required.
Reinforce drivetrain components when justified. Especially if tyre size, vehicle mass or usage intensity has increased.
Develop the body and scale equipment. Lighting, recovery equipment and visual details can then define the character of the build.

This keeps each modification connected to a reason.

Who Should Upgrade the Rock Van?

The strongest reason to choose the Rock Van as a project is that it sits in an interesting middle ground.

It is capable enough to be enjoyed without modification but open enough to become a long-term build.

It particularly suits hobbyists who enjoy:

compact technical crawling
short-wheelbase vehicles
unusual retro van styling
mechanical tuning
repairable RTR platforms
scale lighting and trail details
progressive rather than all-at-once upgrades

Final Verdict

The HobbyPlus CR18P EVO V2 Rock Van does not need an immediate catalogue of upgrades.

Its standard portal axles, metal drivetrain, SOA steering, oil-filled big-bore shocks, two-speed transmission and soft Mudder tyres already form a serious 1/18 crawler package.

What makes it particularly interesting is everything available around that package.

Gears, driveshafts, CVDs, bearings, suspension parts, steering hardware, chassis components, replacement bodies and lighting mean the vehicle can be maintained and developed rather than discarded when something wears or when your priorities change.

The best Rock Van build is therefore not necessarily the one with the most aftermarket parts.

It is the one where every change has a reason.
