§ 02 / About this part

What it is

The PROX CRANKSHAFT BEARING AND SEAL KIT, bottom end. Stocked by Iron Offroad, the UK MX hard parts specialist.

This kit provides the main bearings and oil seals required for a full bottom-end refresh. These components sit deep in the engine cases to support the crank and maintain primary compression. Seals eventually harden or tear, leading to air leaks and lean running. Bearings develop play over high race hours. Replacing the full set ensures your crank rotates true and the crankcase remains airtight. These kits match OEM dimensions for a direct swap during a rebuild. Use a proper press and heat cycle the cases for installation. Fresh seals are vital for consistent jetting and engine longevity.

§ 05 / About Iron Offroad

Iron Offroad

Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. 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 & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
