Product Description:
1999-2013 GM Truck SUV TBSS 4.8L 5.3L 6.0L 25% Harmonic Balancer Underdrive Crank Pulley
Vehicle Fitment: 1999-2013 GM Truck/SUV & Trailblazer SS 4.8/5.3/6.0 (Does NOT fit 5.7L, 6.2L, 8.1L, 4.3L V6, or 6.6L Duramax engines)
SLP's new 25% underdrive balancer for 99-13 GM Truck/SUV incorporates a number of high-quality features you won't find on any other aftermarket unit. Chief among them are a pair of extra-tall belt-retention walls that eliminate the belt-slippage issues endemic to other balancers. Other unique design strengths include 100% steel construction (other brands use steel and aluminum), integral timing marks, and built-in puller-mounting threads.
The keyway in the SLP pulley is designed for both stock and aftermarket crankshafts. The stock crankshaft does not have a key but the sealant on the backside of the GM bolt provided will stop any oil from coming out of the front of the crankshaft snout. There is no need for any additional sealant or gaskets when installing on a stock crankshaft.
