The GPM RUS4102R rear shock set is an aluminium upgrade built to let technicians and experienced hobbyists dial rear suspension behaviour on compatible TRAXXAS 1/10 platforms. The shock bodies are machined from 6061 T6 aluminium to combine structural stability with manageable mass, and the assemblies use suspension oil for consistent damping control.
Design details include a 4mm polished shock shaft to reduce friction and improve wear resistance, threaded preload collars with multiple spring coil options for ride height and initial rate adjustment, and white Delrin washers positioned outside the metal ball ends to minimise direct metal contact at articulation points.
The description reproduces the visible parts and manual listing so installers can confirm included hardware and plan for any additional fasteners or spacers required for fitment.
Engineered as a direct-fit aluminium rear damper alternative for the listed TRAXXAS platforms, RUS4102R pairs 6061 T6 construction with a beefed-up shock shaft and selectable springs to support practical tuning and routine workshop maintenance.
