Kyosho FW05-R/FW05RR Aluminum Rear Differential Housing by 3Racing FW05-024  [FW05-024]

Aluminum rear differential housing for FW05

This is an RC-scale aluminum rear differential housing supplied by 3Racing for Kyosho FW05-R and FW05RR chassis. The part replaces the stock rear diff housing and provides a machined aluminum mounting surface intended for durability and repeatable alignment within the rear driveline assembly.

Compatibility is limited to the Kyosho FW05-R and FW05RR models as stated in the product name. Installation requires basic rear gearbox disassembly and reassembly of the differential assembly; check gear mesh and bearing seating during fitment. The housing functions as a structural component to hold the diff gears and bearings in correct relation to the spur and pinion within the rear module.

Tuning role: swapping the housing can affect how consistently the differential is positioned under load, which can aid setup work when adjusting gear mesh, diff preload, or locating the diff relative to suspension pickup points. The description remains technical and neutral, focusing on compatibility and the housing’s role in maintenance and setup.

Use this aluminum housing when replacing a worn plastic unit or when seeking a more stable, machined mounting surface for rear differential servicing and setup on compatible Kyosho FW05 variants.
