Up front we started with a bare Dana 60 housing found under GM 1-ton pickups from '77 to '90. From there we added a set of Yukon 5:13:1 gears, chromoly axles and a pair of Randy's chromoly Super Joints. The differential we used was the now-discontinued TeraFlex T-locker. The master install kit from Randy's included all the bearings, seals, and hardware to properly install the gears inside the Dana 60 front housing. Altogether these parts cost $1,535.
