Schumacher FT9 Lower Arm Set for Tuning - Factory Pro O-SCP039  [FP-O-SCP039]

FT9 lower arm replacement overview

This Factory Pro FP-O-SCP039 lower suspension arm set is an aftermarket replacement built to fit the Schumacher FT9 touring car chassis. The text below covers fitment notes, installation checks, and how lower arms influence suspension setup for competitive asphalt and carpet running.

These arms are intended as direct-fit replacements at the FT9 lower arm mounting points, restoring suspension geometry and serviceability after original parts wear or damage. They affect roll centre and lateral stiffness, which in turn changes turn-in feel, mid-corner balance, and rear traction on typical 1/10 on-road surfaces.

Installation advice: confirm arm orientation and hinge-pin alignment before final tightening, use the correct FT9 hinge pins and retainers, and check for interference with the servo saver and rear toe links after fitting. Replace any worn bushings or bearings during the swap to maintain predictable suspension motion.

For FT9 racers renewing worn arms or making basic tuning changes, the Factory Pro O-SCP039 set is a straightforward aftermarket option that retains FT9 geometry and supports setup adjustments without chassis modification.
