Richmond Powertrax Grip Pro Differential, 9 Inch Ford, 31 Spline

Powertrax Grip Pro Traction Systems are the latest design in traction using 3 x 2 spiral gear technology for smooth, dependable operation that combines a limited-slip differential with the strength of a fully machined, forged steel case. Because there are no friction plates, no friction modifier additive is necessary.  Always use a 80W-90 weight petroleum based gear oil with a GL-5 (or higher) rating, friction additive/modifiers should NOT BE USED.  Synthetic oils and oils containing friction modifiers are not recommended.  

Powertrax Grip Pro differentials are the ideal solution for just about any light truck, sport utility, and muscle car on the road today. Whether you need the safety of added traction for daily commuting, recreation, work, or just so your muscle car puts power to the pavement instead of burning one wheel up, Powertrax Grip Pro limited slip differentials are your answer.
