This is a billet clutch basket and stock Honda gear assembly. Baskets are machined from 7075 aircraft grade aluminum and hard anodized. Fits all years of the 420 Rancher, 500/520 Foreman, IRS Rubicon and 500/520 Pioneer. **Does NOT fit DCT (auto with ES). Made from a much stronger material than the factory cast aluminum basket along with the hard anodized coating this will prevent wear on the clutch fingers from the clutch plates. The stock cast aluminum baskets get grooving in the fingers over time which causes hard shifting and clutch slippage due to the clutch plates hanging in the wear grooves. These baskets are also machined with tighter tolerances than the stock basket for a much smoother balanced rotation. These come fully assembled with a factory gear ready to install in the engine. If you want the best clutch parts for your Honda this is it! Honda utility billet clutch baskets are only available from Reduction Boss!
