YUK Dura Grip

Limited Slip Differential Assembly

55P GM 17SPL 3.73& DOWN DURAGRIP POSITRACTION, COMPOSITE CLUTCH

A factory thin ring gear was used on 1955-1956 carriers with ribs on the back of the ring gear side. The 1955-1956 open dropout casting numbers end with "306". A new ring and pinion or ring gear spacer is required when replacing the factory 4 series case. Yukon recommends the use of high grade Non-Synthetic GL-5 gear oil and Yukon LSD (Limited Slip Differential) additive for long life and smooth operation. Part number OILADD. The use of synthetic oil is not recommended and may result in aggressive or noisy operation.

Yukon Dura Grip is a positraction limited slip differential that provides smooth yet aggressive traction, giving you the confidence and performance you need across a wide variety of terrains. The Dura Grip is engineered for long life and is completely rebuildable. Dura Grips are constructed with a high strength nodular case, forged 4320 chromoly spider gears, and composite clutches. For unmatched positraction performance, the Dura Grip is the ultimate choice. When your vehicle demands performance, durability and strength, choose Yukon Dura Grip.
