Dana 60 Rear Ends (Strange S60) Drag Racing Bolt-in Rear Ends
The Strange S60 is a vast improvement over factory Dana 60 Rear ends, while still accepting the same components. The casting and oversized main caps are constructed from a proprietary nodular iron which is substantially stronger than cast iron. This has allowed the casting to be made not only thinner and lighter, but also stronger. The heavy duty main caps are fitted with adjuster nuts that eliminate the side carrier shims. Backlash and preload are adjusted by a turn of a wrench, greatly reducing the time and effort to change a gear or differential. The 9.750” ring gear can endure a tremendous amount of abuse- equal to a 9” Ford at a fraction of the price. It is also more efficient , taking less horsepower to drive the ring and pinion. The S60 weighs 15 lbs. more than a comparable 9” rear end, and only 20-25 lbs. more than an aftermarket 12-bolt. The S60 rear end is equipped with 35-spline axle shafts without costly upgrades. All castings feature a drain plug located at the bottom. Mopar applications have a machined provision to accept factory or aftermarket pinion snubbers. GM F-body applications have the torque arm mounting location cast into the unit, while A-body and G-body feature integrated upper control mounts. The HD 1350 series pinion yoke is larger than any factory yoke and needs to be accounted for when ordering the driveshaft.
STREET/TRACK: The S60 is equipped with a Spicer Trac-lock (clutch style) posi unit, Standard gear set, 35 spline Alloy axles, 7/16” or 1/2” wheel studs, HD 1350 series yoke, u-bolt kit, and steel rear cover. The Trac-lock is designed for street use in vehicles that will not be raced. The optional Truetrack (helical gear) differential is a great choice for a Street / Track applications. Gear ratio choices are 3.54, 3.73, 4.10, 4.30, 4.56, 4.88, 5.13, & 5.38. Upgrades are available to the differential and wheel studs. Options include a chrome moly 1350 series yoke, Strange aluminum black powder coated cover, LPW HD aluminum cover, and satin black powder coated housing. The steel cover would also be powder coated when this option is ordered.
F-BODY: This assembly comes standard with the upgrade to the Truetrack (helical gear) differential, Standard gear set, 35 spline Alloy axles, 12 mm or 1/2” wheel studs, HD 1350 series yoke, u-bolt kit, and steel rear cover. Gear ratio choices are the same as above. The rear can be configured for 82-92, 1993-1997 or 1998-2002 factory disc brakes and 3 or 4 channel ABS. Aluminum covers can not be used due to the close proximity of the rear end to the gas tank. Upgrades include provisions for ABS. 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.
