Aluminium Power Steering Reservoir
For Toyota FJ Cruiser & Toyota 4Runner
(Replaces 44360-60321)

The factory plastic power steering reservoir on the 4Runner and FJ Cruiser struggles with long-term heat exposure. Over time it fades, becomes brittle, and can even crack, which leads to leaks and inconsistent steering assist. The stock design also allows air bubbles to mix with the fluid, creating noisy, uneven steering response that takes away from smooth daily driving and off-road control.

Many aftermarket metal reservoirs fix the durability issue but come with a different problem—they’re fully sealed. You can’t see the fluid level unless you remove the cap every time, which turns simple checks into an annoying extra step.

This upgraded aluminium reservoir solves all of these issues at once. It replaces the aging plastic with strong billet aluminium and adds a built-in baffle to reduce bubbles for more stable steering. A reinforced clear window lets you check fluid levels instantly, so maintenance stays simple and quick.
