Crank Damper Pulley specially for HKS Capacity Upgrade kit VR38DETT 4.3L reduces the torsion of the crankshaft.
Features
- It reduces the peak value of the torsion of the crankshaft that occurred from the sympathetic vibration point.
- HKS and ATI PERFORMANCE PRODUCTS cooperatively developed the dedicated product for VR 4.3L because each crankshaft has a different sympathetic vibration point.
- The optimized product specifications were gained through measuring the actual torsion at the engine bench test.
- Allowing the combination use of the HKS fine tune V-belt because the diameter of the pulley for the V-belt is the same as the stock one.
