BATTCAVE

This item comes packaged in a labeled re-sealable bag, helping to keep storage and recognition easy.

Since the original JOK3R launched in late 2023 and then the 2025 JOK3R-R update, we have continued to develop and refine the platform through countless hours of racing, testing and customer feedback.

JOK3R+ Carbon Surface GRP (CSGRP) 

A premium GRP alternative for the JOK3R+ range, combining our premium GRP core with a distinctive 3K glossy carbon surface finish.

The CSGRP chassis not only retains the familiar characteristics of our proven Black GRP chassis, but the slot-less LiPo-only design also provides a wider flex tuning window for different track conditions and setups. The LiPo-only design also gives the chassis an overall cleaner look too.

What's New with the JOK3R+

New Short A-Arms & Ride Height Shims

New short A-arm design 

Developed to improve driveability and provide another front-end tuning option, together with new ride height shims for adjustment of the front ride height.

*The existing JOK3R-R Long A-Arms remain fully compatible with the JOK3R+.

2mm Long Top Decks - Now Standard

Previously available as an optional tuning part for the JOK3R-R, our 2mm Long Top Deck design is now supplied as standard across all JOK3R+ kits, providing additional flex tuning options straight from the box.

New JOK3R+ V2 Pod Bobbins

Revised rear pod bobbins introduced with the JOK3R+, These new pod bobbins are not only stronger but they are designed to provide uniform preload which is set by the band itself. This allows racers to adjust the pod roll centres without affecting the sideband’s preload.

Revised TPU Front Bumper

The TPU front bumper has been redesigned to accommodate the new Short A-Arm design while remaining fully compatible with the original JOK3R-R Long A-Arms.

Revised Steering Bump Stop

The updated TPU steering protection are now universal fit for both side of the car.

Aqua Response Side Bands

The ever popular Aqua Silicone Response Side Bands are now supplied as standard with the JOK3R+.

Improved Plastics throughout

General improvements to materials and manufacturing process to further increase the durability the car.

Now Available as a Full Kit

For the first time in the history of the JOK3R platform, the JOK3R+ is now available as a full self-build kit, complete with our comprehensive hard copy user manual. *For those who would prefer their car ready-built, a pre-assembled slider option will also be available, subject to availability.

New JOK3R+ Tuning Options Available Separately.

• 2mm T7075 Alloy Pod Plate - significantly increases the pod movement compared with the standard 3mm pod plate, providing greater pod freedom for improved weight transfer and bump handling when cornering at speed.

• Low Roll Centre Pivot Ball - lowers the rear roll center for increased rear grip and traction, allowing additional rear-end find tuning options.

• Fat Side Bands - a new trio of 2.5mm side-band range providing a simplified chassis tuning option. Available in Soft, Medium and Hard, colour coded to match our current Side Band range.

JOK3R+  The next evolution of the BattCave JOK3R platform.

JOK3R+ T-7075 Alloy

Combining increased chassis rigidity with a significantly lower centre of gravity, the T7075 Alloy chassis brings out another level of handling characteristics to the JOK3R+ platform.

Manufactured from 2mm T-7075 aluminium alloy with a black anodised finish, the reduced chassis thickness significantly lowers the centre of gravity of the entire car and its roll centre. The increased rigidity and low material resonance provide a more forgiving platform that can be pushed harder, while the lower centre of gravity and roll centre improve stability, traction and overall handling. 

This combination is particularly effective in medium to very high traction conditions.
