The Tamiya 84048 - TA05 Lightweight Urethane Bumper is a direct-fit spare for the TA05 chassis offering reliable shock absorption. The high-quality sponge composition helps dissipate impact forces and resists compression, making it a sensible upgrade for drivers who race on mixed surfaces.
Urethane bumpers combine flexibility with strength, so they deform under load and return without cracking. That resilience reduces the chance of damage to the chassis and front suspension links when you clip a kerb or make contact at speed.
Install the bumper with the factory mounting points aligned for a secure fit. Check the bumper after rough runs and swap it out if the sponge shows permanent deformation to keep protection consistent lap after lap.
