The 12 bolt design of this differential allows for easy installation and removal, making it a popular choice among enthusiasts and professionals alike. With a 30 spline design for the axle shafts, this differential offers increased strength and durability, ensuring reliable performance even under heavy loads.

This Scitoo Limited-Slip POSI Differential is a must-have for anyone looking to elevate their vehicle's performance and handling capabilities.
