The ROCHE 340035 Front Upper Arm Caster Block is a purpose-made upgrade for the S40050 chassis that helps sharpen steering input and stabilise the front end. It is aimed at drivers seeking more consistent lap times through improved control.
Designed for longevity, the ROCHE caster block uses tough materials and accurate tolerances so it maintains alignment under stress. It is engineered to slot into the S40050 layout with minimal adjustment.
After fitting this caster block you can expect crisper steering and steadier corner exits, which supports confident throttle application. It suits competitors and serious hobbyists tuning their front-end behaviour.
