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

Machined rear differential housing for FW05

This is an RC-grade aluminum rear differential housing intended for Kyosho FW05-R and FW05RR chassis. The part replaces the factory plastic housing and provides a machined mounting face aimed at greater durability and repeatable alignment inside the rear driveline module.

Compatibility is limited to the Kyosho FW05-R and FW05RR models as noted in the listing. Fitting the unit requires basic rear gearbox disassembly and reassembly of the differential assembly; confirm gear mesh and bearing seating during installation. The housing acts as the structural mount for the diff gears and bearings relative to the spur and pinion in the rear module.

Tuning impact: exchanging the housing can stabilise the differential position under load, which helps when fine-tuning gear mesh, diff preload, or locating the diff in relation to suspension pickup points. The explanation stays technical and factual, focusing on serviceability and setup effects.

Choose this aluminum housing to replace a worn plastic unit or to gain a stable, machined mounting surface for rear differential servicing and precision setup on compatible Kyosho FW05 variants.
