Powertrax Grip Pro traction systems are the latest design in differential technology. They combine the smooth operation of a limited-slip differential, with the strength of a fully machined, forged steel case. Using 3x2 spiral gear engineering, the Powertrax Grip Pro delivers progressive and variable traction. Based on throttle input, you are in control of how much traction is applied. These differential systems are great for use where finesse is just as important as brutal traction. On the road or track, in the rain or snow, Grip Pro is a winner! The systems come fully assembled and there are no friction plates—so you can use any gear oil you like, including full synthetic and racing lube.

MechMan 6-phase hairpin high-output alternators offer a solution to the inadequate alternators that come from the factory on specified vehicles. These replacement units feature twin rectifiers with 12 massive press-fit diodes, as compared to the small 8-diode rectifier in the stock alternator. Even mild performance builds will typically consume more amperage than what stock alternators can provide. Hairpin stator technology provides better high-rpm durability and better resistance to heat from the turbo manifold. The alternators utilize a high rpm-friendly larger diameter pulley, and bolt directly in place of the original equipment. Select the high-output racing alternator model recommended for your application. Note: A 4-gauge or larger positive and negative cable needs to be run between the alternator and the battery terminals for proper function.
