Power Loks for Chrysler, Spicer® & GM GM 4 Spring Posi’s, Ford Trac Locs® & Dura Grips
Yukon Reproduction Power Lok The Power Lok units were originally built by Spicer® but in many cases have been discontinued, making them extremely hard to find. Knowing their popularity and durability, Yukon decided to have many of the long discontinued units reproduced and also to have some made for applications that were never originally offered. The Power Lok is a clutch driven positraction that uses a ramping action to load the clutch pack becoming progressively more aggressive as slippage occurs. These units are extremely durable in high horsepower applications.
