This aluminum rear chassis brace is an RC-scale hop-up produced for ENDURO SENDERO TRAIL TRUCK platforms, offered by GPM under part ES015R. It targets the rear chassis area to reduce flex and improve structural repeatability when driving on rough trail layouts.
Manufactured from 6061 T6 aluminum, the brace balances low weight with high tensile strength to provide a stiffer rear-end response without adding unnecessary mass. The kit includes the brace itself plus fasteners so the part can replace the stock rear reinforcement at the factory mounting points.
Contents supplied with the part are the chassis brace (1 pcs) and stainless steel flat head screws 3x10 (4 pcs). Screws are provided to mount the brace to the existing rear chassis attachment points; check thread engagement and fastener tightness after initial runs.
In tuning terms, adding a rear chassis brace increases rear chassis stiffness which can translate to firmer rear-end handling and more predictable traction on uneven surfaces. Use this part alongside suspension and shock tuning to balance overall chassis behavior rather than expecting it to change handling by itself.
