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.

BattCave JOK3R+ Mini Short A-Arms

Developed specifically for the BattCave JOK3R+, our new Short A-Arms form an important part of the revised JOK3R+ front suspension.

The shorter A-Arm design has been developed to help give the JOK3R+ its easier, more forgiving driving characteristics, while retaining the precise and responsive front-end feel expected from the JOK3R platform.

Produced using our revised high-performance material, the new Short A-Arms offer increased strength and improved impact resistance, helping to make the JOK3R+ front end more durable without compromising precision or performance.

Each pair is also supplied with our new Front Steering Rubber Limiters. These act as impact absorbers, helping to dissipate heavy impacts through the front suspension and protect the surrounding components, further improving front-end durability.

Caster and camber geometry is built directly into each A-Arm, allowing racers to quickly change the front-end characteristics of the car and fine-tune the setup for different track conditions and driving styles.
