High-precision rear housing for FW05 platforms

An aluminium rear differential housing engineered for Kyosho FW05-R and FW05RR rear modules. The component replaces the standard plastic housing and provides a machined mounting face to support consistent alignment and robust service intervals within the rear driveline.

Compatibility is limited to the Kyosho FW05-R and FW05RR configurations listed. Installation follows standard rear gearbox disassembly and diff reassembly procedures; during fitment, verify gear mesh tolerances and seating of bearings. The housing functions as the structural datum for diff gears and bearings relative to the spur and pinion.

Tuning and setup: installing the machined housing helps maintain differential position under torque, which aids repeatable tuning of gear mesh, preload settings, and diff positioning in relation to suspension pickup geometry. The description is technical and focused on practical upgrade benefits for competitive setups.

Use this machined aluminium housing when a stable, serviceable mounting surface is needed to support precise rear diff setup and repeatable performance on compatible FW05 cars.

A machined aluminium housing provides a rigid, repeatable datum for the differential, improving consistency under load and simplifying setup work for gear mesh and preload adjustments.
Ensure bearings are fully seated and that gear mesh falls within normal tolerances. Check that the housing aligns cleanly with the rear module before final torqueing.
By reducing flex and offering a repeatable mounting reference, the housing can contribute to more consistent diff behaviour during repeated runs, aiding setup repeatability.
For most stock rear modules this housing offers sufficient rigidity; review your overall drivetrain setup and replace worn bearings or gears to ensure the entire assembly is race-ready.
