Designed for ARRMA chassis, this rear lower suspension mount is machined from 7075-T6 aluminium and fitted with brass inserts to enhance hinge-pin engagement and service life. The part concentrates on reinforcing the rear gearbox area to curb lower-arm pivot flex and help retain alignment during aggressive use.
The item supersedes factory part number AR330379 and is dispatched with the hardware detailed below. The aluminium body improves wear resistance compared to stamped stock parts, and the brass inserts give a dedicated bearing surface for hinge pins to reduce play without adding brittleness.
Fitting guidance: the mount locates at the rear lower suspension point on supported ARRMA 1/8 and selected 1/7 6S models. Use the supplied grade 12.9 black flat head screws for secure fastening and verify hinge-pin seating and arm alignment after installation. This is a chassis-level tuning component aimed at stabilising suspension behaviour rather than altering geometry.
For model builders preserving or upgrading ARRMA 6S cars, this GPM rear lower suspension mount is a straightforward aluminium replacement to cut hinge-pin play and keep the rear lower arm more stable under load; install with the supplied hardware and re-check alignment after fitting.
