Overview

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 3x2 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. And don't forget that there is no friction modifier additive necessary because there are no friction plates!

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
