Strange S60 Rear End With GM F-Body Mounts 35 Spline Alloy Axles and Helical Gear Differential

Description

Dana 60 F-Body Rear End

The Strange Dana 60 F-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.

F-Body Specifics

The S60 rear end is equipped with 35-spline axle shafts without costly upgrades. The castings have a drain plug on the bottom. The GM F-body application has the torque arm mounting location cast directly into the unit. The HD 1350 series pinion yoke is larger than the factory pinion yoke and this will need to be taken into consideration when ordering the driveshaft.

This S60 Rear End is equipped with a Strange S-Trac (helical style) posi unit, Standard gear set, 35 spline Alloy axles, 12mm or 1/2” wheel studs, HD 1350 series yoke, u-bolt kit, and steel rear cover. Upgrades include provisions for ABS & 5/8” wheel studs. Options are a chrome moly 1350 series yoke and satin black powder coated housing. The steel cover would also be powder coated when this option is ordered.
