This rear chassis brace is an RC-scale replacement part designed for HPI Bullet platforms and produced by JAZRIDER under model BUL-18008-GU. The gunmetal alloy rear brace is intended to increase rigidity in the rear section of the chassis for Bullet 3.0 MT and ST nitro variants.
The component is tuning-focused: by stiffening the rear it changes throttle transition behavior and rear traction on uneven terrain. It mounts to the standard rear attachment points and serves as a structural reinforcement rather than a powertrain modification.
Fitting advice: align with the rear bulkhead fasteners, check for any contact with exhaust or fuel tank plumbing on nitro setups, and use thread locker on metal fasteners if desired. After installation, re-evaluate chassis geometry and suspension to account for the stiffer rear response.
