Tamiya Ford F350/Toyota Hilux/Tundra Precision Diff Housing Upgrade F350-F4 by GPM  [F350-F4]

Precision machined alloy differential housing cover

This machined alloy differential housing cover is a direct-fit RC replacement for Tamiya Ford F350, Toyota Hilux, and Tundra pickup models. It provides a stiffer alternative to stock plastic covers to help maintain alignment and reduce flex in the differential area under load.

Verify compatibility with the listed Tamiya chassis references prior to installation. The part is intended for hobby RC trucks and not for full-size vehicles. Installation normally uses the vehicle's existing screw locations; confirm screw length and thread engagement during reassembly to avoid fastener damage.

From an upgrade perspective, the cover acts as a structural hop-up that reduces differential housing flex, helping to stabilise gear mesh and support consistent pinion and spur engagement during higher torque or heavier payload operation. This makes it suitable for incremental drivetrain reinforcement and tuning workflows.
