I have a used 3.1 pulley and a new hubs with bolts and allen wrench, this is a great upgrade for someone with a stock tune, this pulley will give you faster max boost of 16psi. Asking $70.00 shipped in us or $75.00 canada new they go for $100.00

um i think you better do your homework.. stage 3 is only 2.99(76mm).. stage 2 is 3.07(78mm).. stock is 3.35.. injectors max out at anything below 3.15, so to be safe i wouldnt run anything smaller then 3.2 on stock tune.

3.1" pulley is safe on a stock tune. Best with a custom tune to take full advantage. I have a friend that I tuned for a 3.0 on stock injectors that ran that way for 15k without issue and IDC was never above 88%

Dont buy it if ur afraid, Im not forcing it on u. There are many people on here running a 3.0 inch pulley on stock tune, do your home work, GM stock tune is very rich. I've used this pulley for several mounths with absolutly no problems except taction

Thanks for the support.

well sorry for the thread jack man.. the pulley size and stock injectors i guess is a debated subject, cuz ive seen the injectors at 110% with a 3.1 ... but anyways the main point of my post was to clarify the gm pulley sizes... good luck with the sale.. bump for a good deal.
