Ensure the longevity of your Cummins diesel engine with the Fluidampr harmonic balancer + Fluidampr crank pin drill fixture installation kit for 2001-Current GM 6.6L Duramax. With heat-treated, high-strength ARP bolts and a diamond-impregnated friction washer, this kit securely mounts your damper, preventing any unwanted movement.
My pin broke off in my crankshaft causing my serpentine belt to not properly work causing my Duramax to violently shake and other crazy issues with fuel, battery and power steering/brakes. Also, the main bolt for the harmonic balancer also backed out throwing the entire pully out of alignment. Had my shop install this along with a secondary pin and the new bolt purchased from here. My duramax is now running so smoothly it doesn't feel like an old 1st generation truck! Customer service was amazing and I would highly recommend them for parts! Thank you!!
