i have a ur crank pulley (stock diameter) just wondering what belt it uses. i understand the other pulley uses serpentine belt. i'm not too sure if it uses the same kind of belt or not?

lol i'm so confused...someone please put me on the right path

Same belt spec - OE or OE replacement. Gates is recommended but not required; GY Gatorback may not be optimal due to something with the design of the edge (iirc).

Double, double check that belt fitment for your year/trim. Pretty sure all 3G TL are the same.

i knew you'd come along bearcat94...but if its the same belt for both types of pulleys why do you need to replace the belt for the other kind of pulley? noob

the stock diameter light pulley uses a GATES belt in the same size as stock
Gates has an edge that fits the UR pulley much better than other brands-
use it so you wont get noise

The Underdrive pulley uses a different belt size because the total length has changed

for correct part number call Josh at Excelerate - website www.excelerateperformance.com

It IS the same belt for the OE pulley and the UR Stock pulley. Same length. Called a "drive belt" or "serpentine belt" - thats just a generic description.

As 01tl4tl mentioned Gates brand had a different edge that fits the UR pulley a little better, but you could re-use your OE belt.

That pulley is over-rated.
