§ 02 / About this part

What it is

ProX rear shock seal head kit to fit Yamaha IT175 (1981–1983); Yamaha YZ125 (1978–1983, 1986–1988); Yamaha YZ250 (1976–1981, 1983–1988); Yamaha YZ465 (1980–1981); Yamaha YZ490 (1983).

This assembly restores the integrity of your rear suspension unit. It sits at the base of the damper body. It contains the oil and nitrogen charge while the shaft moves through its stroke. Dirt and heat eventually degrade the internal seals. This leads to fluid leaks and a loss of damping control. This unit replaces the entire assembly for a faster rebuild. It matches OEM specifications for a precise fit. Ensure the shaft is free from burrs or pitting before installation. Use a dedicated seal bullet to slide the assembly over the threads.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron Stable — a UK shop for motocross, enduro, and trail-bike hard parts. Every fitment lives on the site, listed against KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is the data: fully enriched fitment so you find the right part for your bike quickly and get it fitted accurately. Brands you'd find on a paddock workbench — pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere; dirt and e-moto only. We operate from our storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. The business has a rich motorcycle history across multiple moto brands — the photos show where we came from — and recently pivoted into hard parts and online retail.
