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.
