One complete, new chain guide assembly for GP models to replace the heavy stamped steel unit with the wimpy little rubber wheels on 6mm bolt axles. This set up is lighter, more durable, and higher quality than the stock guide and looks totally awesome on the bike. The assembly bolts on in minutes with no modifications. These rollers guide the chain smoothly onto the sprocket without any drag at all. They will also outlast the oem set up 10 times. A must for any ML model Husky owner especially those racing the GP models in AHRMA competition. The assembly consists of (2) 6061 aluminum backing plates, machined to exact specs using stainless steel socket head cap bolts, washers and nyloc nuts. The chain roller wheels are high quality polyurethane rollers with 98A durometer hardness for long life assembled with precision contact sealed bearings and seals to keep water and dirt away from bearings.
