Description

Upgrade your vehicle's traction with the Spartan Helical Limited Slip Differential from USA Standard Gear. Designed specifically for Dana 30 front differentials with a 27 spline count and gear ratios of 3.73 or higher, this unit provides a significant performance boost when wheel slippage occurs. The advanced helical gear design uses pre-loaded worm gears to funnel power directly to the tire with the best traction, ensuring better control in challenging conditions. This differential features a unique 10-pinion design. By utilizing more points of contact and a larger surface contact area compared to standard 6-pinion or 8-pinion units, it achieves superior load distribution and strength. Built for long-term reliability, the Spartan Helical LSD is engineered for maintenance-free service. Whether you are looking to improve off-road capability or general driving stability, this Spartan Locker component delivers smooth engagement and linear traction for a more consistent driving experience.

Provides smooth engagement and linear traction for predictable vehicle handling.
