Only the best components from names such as Mark Williams, Strange, Dutchman, Currie, Summers Brothers and Ford Racing are used. SDGA has built differentials for many cackle dragsters such as Tommy “Watch Dog” Allen and Don Prudhomme.


They can build front and rear differentials for all Off Road applications including Toyota Pre Runner to Trophy Truck and everything in between. We use the best components from Mark Williams, Moore Performance, Strange, Currie and others. All Off Road assemblies come with Assembly Specification sheets and photos of what’s inside. From a Ratio Change to 40 Spline Spool, Axle and Brake packages, we can do it!

SDGA can furnish custom made parts that have been used in various differential conversions.

The company also offers conversions to automatic overdrives and they are an Authorized Bowtie Overdrives Dealer.
