The ROCHE 340035 Front Upper Arm Caster Block is a specialist upgrade tailored to the S40050 chassis. It helps refine steering response and enhances stability during aggressive cornering.
Built to cope with regular racing, the ROCHE caster block uses durable materials and precise machining to maintain alignment under load. Its profile matches the S40050 to reduce installation fuss and preserve handling geometry.
After fitting this caster block drivers typically notice firmer steering feedback and reduced wandering on straights, which aids consistency over a race program. It suits both club racers and weekend tuners.
