Elite Heli-Trac Posi LSD

Elite Heli-Trac LSD uses the latest spiral gear technology to produce one of the longest lasting and best performing differentials on the market today. No more clutch chatter or worn out parts. Heli-Trac LSD will retain it's same torque biasing throughout it's life span. Clutch and Cone type differentials lose their torque biasing as they age and parts begin to wear. Heli-Trac differentials offer smooth operation for daily drivers, yet are strong enough for many racing and off-roading applications. Each Elite Heli-Trac LSD includes a Limited Lifetime Warranty
