Please Select If You Would LikteTo Add Triple Disc Billet Torque Converter Upgrade
Upgrade your factory torque converter to our HDP spec triple disc billet torque converter. Running an aftermarket torque converter offers many benefits. From replacing the failure-prone stock torque converter assembly, to upgraded clutches and higher stall speeds. Running a higher stall speed torque converter will help with drivability, reliability and enhance overall vehicle performance. When running an aggressive camshaft an aftermarket torque converter ugrade may be required. 
(Converter upgrade cost is for parts and fluids only, there are no extra labor charges since we remove your engine to perform the engine work)
