Description

The Zumbrota Drivetrain YGK2344 is a comprehensive re-gear kit designed to significantly enhance traction and durability for vehicles equipped with a Chrysler 8.75” differential and 89 case housing. This kit integrates a high-performance Yukon Powr Lok positraction limited-slip differential (LSD) with an upgraded ring and pinion set. The included 3.23 gear ratio and 29 spline pinion gear are designed to provide more aggressive acceleration. The kit features a 12-bolt ring gear for robust performance. This kit is suitable for a range of classic muscle cars, including coverage for 1970-1973 Dodge Challengers, 1968-1973 Road Runners, and 1964-1973 Plymouth Barracudas. It is also compatible with 19 other models and any custom builds utilizing a Chrysler 8.75”/89 housing differential. Key specifications include a 3.23 gear ratio, 29 spline pinion, and a 12-bolt ring gear. The inclusion of the Powr Lok LSD is central to improving grip and handling.
