The POWERTRAX Grip Pro is the latest design in traction adding differential technology. It combines the smooth operation of a limited-slip differential, with the strength of a fully machined, forged steel case.Using 3×2 spiral gear technology, the POWERTRAX Grip Pro delivers progressive and variable traction. Based off of throttle input, you are in control of how much traction is applied. Great for use where finesse is as important as brutal traction is. On the road, in rain & snow, and on the track, Grip Pro is a winner!The POWERTRAX Grip Pro comes fully assembled. Because there are no friction plates, no friction modifier additive is necessary. Always use 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 TRACTION SYSTEMS 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, the POWERTRAX TRACTION SYSTEMS are your answer.
