The 3Racing 416-03/LB is a dedicated rear bulkhead developed to improve the rigidity of the Tamiya TRF 416 chassis. Manufactured with close tolerances to ensure consistent fitment, it is intended for drivers who refine handling through chassis stiffness adjustments.
Replacing the standard rear bulkhead with the 3Racing unit reduces rear flex and stabilises suspension pivot points under load. This aids in predictable toe and camber behavior, allowing more precise tuning of roll center and anti-squat characteristics for competitive setups.
During installation, use calibrated torque settings for fasteners and confirm driveline alignment to avoid binding. After fitting the 3Racing bulkhead, re-evaluate rear shock valving and spring rates to match the increased chassis stiffness on the Tamiya TRF 416.
