Tamiya Ford F350/Toyota Hilux/Tundra Machined Diff Housing Cap F350-F4 by GPM  [F350-F4]

CNC-style machined diff cap

This machined alloy differential housing cover is an RC replacement part for Tamiya Ford F350, Toyota Hilux, and Tundra pickup models. It installs as a direct-fit upgrade over the stock diff cover, increasing stiffness compared with standard plastic covers and helping keep drivetrain geometry under load.

Check fitment against the listed Tamiya chassis references before installing. The part is intended for hobby-grade RC trucks only and is not suitable for road vehicles. Installation generally uses the vehicle's existing screw positions, so confirm screw lengths and thread engagement during reassembly to avoid damaging fasteners.

In tuning terms this component acts as a structural hop-up: reducing differential housing flex improves gear mesh stability and helps maintain consistent pinion and spur engagement when running higher torque or heavier loads. It is a recommended addition for stepwise drivetrain upgrades and durability tuning.
