Compatible with Chevy/GMC C/K Series Pickup & Blazer/Jimmy/Suburban from 1963-1987.
Are you struggling with traction or experiencing noise from the GM 12-bolt in your truck?
Hurst Engineering Limited Slip Differentials offer strength and traction, but are not overly aggressive for street use.
These differentials feature 4-spring, composite, clutch-style, limited-slip carriers with internal gears machined from forged 4320 steel and stronger teeth.
Designed for GM 12-bolt 30 spline rear ends, they are compatible with 2.76-3.42 ring & pinion gears.
Upgrade to a limited slip unit from an old open differential.
Also compatible with 3.73 & up thick gears.
The use of high grade Non-Synthetic GL-5 gear oil and Yukon LSD additive (or similar) is recommended for long life and smooth operation.
Synthetic oil is not recommended and may lead to aggressive or noisy operation.
