    Requires Strange Spool Bearing Kit 873-D1584

    Strange Spools are used in a wide variety of race cars to replace heavier and weaker cast-iron differential carriers. Spools permanently lock both axle shafts together so that both rear tires will always turn at the same speed. Many Strange spools allow the use of larger axle splines that tremendously increases axle strength. The lighter and stronger steel spool also improves ring and pinion life by providing a more rigid gear mounting. Many rear end problems are caused by deflection of stock cast-iron carriers or failure of differential side gears, these problems are eliminated with a Strange spool.
