S60 rear end / A-Body / spool / 40 pro race axles / coil spring mounts
The Strange Dana 60 A-Body Rear End (S60) is a huge improvement over the OEM Dana 60 rear axle while still accepting the same components.
Strange has designed a casting that is not only stronger but also thinner and lighter than the factory rear axle. The main caps and casting is made from a proprietary nodular iron. This formula is considerably stronger than cast iron. We eliminated the side carrier shims and the heavy duty main caps are fitted with adjuster nuts. The adjuster nuts allow the backlash and preload to be adjusted by a turn of a wrench. This in turn greatly reduces the time and effort to change a gear or differential.
The 9.750 inch ring gear can withstand a large amount of abuse. Equal to that of a 9 inch Ford gear, at a fraction of the price. It also happens to be more efficient, using less power to drive the ring and pinion. Comparing the weight to a similar 9 inch rear end the Strange S60 weights just 15 lbs more. If you compared it to an aftermarket 12 bolt it is around 20lbs more.
