Lowbrow Customs Motorcycle Primary Drive Locking Block Tool

If you are working on the primary or clutch on your Harley-Davidson, Triumph, BSA, Norton, Honda, Yamaha or anything else, this tool will save you a lot of headaches! This grade 95A, high tensile polyurethane locking block can be inserted between your chain and sprocket or clutch basket, locking it in place while you install or remove primary or clutch components. This material is tough enough to take the pressure and stop your primary from turning while you torque hardware in place, but soft enough to not damage your chain, sprocket or pulley. Works well with chains as well as belt drive systems. The bright green helps ensure that you don’t leave it in your primary before you install your primary cover and hit the road! Made in the USA.
