TRF420 B-Parts Bumper, spare part for chassis

TRF420 B-Parts Bumper is a dedicated spare set for TRF420 chassis cars, built to put a damaged front-end component back into service with the correct replacement part for this platform. The set contains 1 bumper and matching B-parts on a moulded sprue, giving a direct route to repair work after contact on the track. The bumper design has been revised so it does not affect the roll characteristics of the chassis, which matters when a car is already tuned around a known handling balance. New body mounts with a 2 mm offset add another adjustment point by allowing different attachment positions. That layout supports body mount relocation to fine-tune the center of balance, using the replacement parts not only for repair but also for setup correction. The moulded format keeps the parts grouped together before removal from the sprue for fitting. In workshop use, this spare set suits routine maintenance between race meetings, rebuilds after heavy contact, or a chassis refresh before the next setup session. Kept in a pit box or parts case, it gives TRF420 owners the exact bumper-related pieces needed for a platform-specific replacement instead of adapting a general component.
