Introducing our new JOK3R silicone side bands!

Custom-moulded in silicone for better consistency.
Colour-coded for easy identification.
Wider tuning options.
Available in 3 different sets:

• Aqua – Neutral response set
• Lime – Medium response set
• Pink – High response set

Each set contains a total of 6 bands: 2 thick + 4 thin bands.

Also introducing the new BattCave Side Band Organiser Box - designed by Aiden Monk!

Designed by Aiden Monk and proudly featuring the BattCave logo, this sleek side band storage solution lets you easily transplant your existing side band holders into a smart, well-fitted box. Perfect for those who likes a tidy pit table.

*Picture of the box with inserts and bands installed (NOT INCLUDED!)

Recommended Usage:

•  Choose thick or thin bands (or a combination) to set your desired lean control (Thin allows more lean, Thick allows less lean).For example, you may want to use thin bands to allow more lean when grip is low, and thick bands when grip is high.
• Choose the colour to set your car's steering response. For example, you may want to increase your car's steering responsiveness on technical tracks, and reduce it on wider, flowing tracks. 

Care:
To keep the bands in tip-top condition, when not in use we recommend storing them in their case and avoid contact with solvents or brake cleaners.

We’ve made small design optimizations to the BattCave JOK3R Mini A-Arms with the new V2 design!

• +0.5mm Ride Height Adjustment: This change provides additional front clearance, perfect for those running ultra-small front tires.

• New Stronger Material: Improved impact dissipation and overall parts durability while maintaining the quality and performance you expect from BattCave.

• All New Steering Buffer Limiters: For a limited time, every V2 design set includes our all-new steering buffer limiters—designed to better dissipate impacts and enhance durability of the front end in hard impacts.

Currently, we are offering the 2+0, 2+1, 4+1 and 7+1 geometry options, with our other geometries rolling out over the next few weeks.

Important: We do not recommend mixing V2 arms with the original release spec. Due to the +0.5mm ride height adjustment, mixing will result in uneven ride height on the front end from side to side.

🦇 Easy Adjustability: The built-in geometries make it simple to make changes and tweaks, enabling you to quickly and easily dial in the perfect setup for your driving style and track conditions.

At BattCave, we specialize in pushing the limits of RC performance with cutting-edge 3D printing technology and precision engineering. Our JOK3R Mini A-Arms are crafted for those who seek the ultimate in customization and control, with the added benefit of easy adjustability to suit any racing condition.

SKU: JKR-3A51, JKR-3A52, JKR-3A41-V2, JKR-3A42, JKR-3A20-V2, JKR-3A21-V2, JKR-3A71-V2

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+ 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.

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

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.
