§ 02 / About this part

What it is

The PROX VALVE SHIM 8.90X2.12 5 PCS REFILL KIT, top end. Stocked by Iron Offroad, the UK MX hard parts specialist.

Maintain precise valve clearances to ensure your top-end operates at peak efficiency. These shims sit between the cam and the valve stem to set the lash. Over time, valve seats wear and valves stretch, closing this gap and causing hard starting or power loss. These shims are a direct replacement for OEM components in many modern four-stroke engines. Always verify the thickness with a micrometer before fitting. Ensure the shim sits perfectly flat in the retainer to avoid top-end damage. Block the cam chain tunnel during installation to prevent losing parts into the crankcase.

§ 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.
