This is a brand new and never installed SuperGrip upgraded s/c pulley by Underdog Racing Development. This pulley is 2.825" compared to the stock size which is 3" & will increase your boost 1.5-2psi for a gain of around 20-25hp. Those that have made the change to this pulley say that it really wakes up the s/c low, mid-range and on the top-end. They say makes a substantial difference in how the truck feels, is how they expected the truck to feel with a s/c and is how the s/c should have come from the factory. No other modifications to the truck are needed to use this pulley which is another reason they'er so popular. I'll take $**SOLD** shipped and will even throw in FREE USPS PRIORITY SHIPPING! First post of 'I'll take it' gets it and asking questions does not entitle you to buy ahead of someone who posts I'll take it.

Thanks for looking!
