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. Strange Pro Race Spools are forged with Strange designed tooling from premium steel. The forgings are machined on all critical surfaces by computer controlled machining centers and are fully heat-treated. Super lightweight aluminum spools are precision machined and are ideal for applications where reduction of weight is essential (call to discuss your specific aluminum application). Strange Pro Race Spools are the lightest on the market and are offered with Strange Pro Race axles at package saving prices. Pro Race steel spools have a lifetime replacement policy.
