We offer a wide range of original or competition products, including PROX, HINSON, etc. Everything is in stock and available quickly. Don't neglect your clutch housing. If it starts to play up, it's time to change it. At best, this can just cause premature wear of your clutch. At worst, your entire primary transmission and gearbox will have to be replaced. As a reminder, the clutch housing is used to transfer power from the crankshaft to the gear. It's an important part of your engine.
