Underdrive Pulleys

[StL3GTJLH]

I installed underdrive pulleys about 6 months ago, with a brand new serpentine belt, The belt is already really worn on the inside of the belt, i was wondering if I needed to put any washers or anything inbetween any of the pulleys, any information would help. Thanks

I haven't heard of a problem like this from anyone else. What pulley's did you get? Did you use the stock belt?

Yeah same size belt, the pulleys are ford racing pulleys.

weird...if u think a washer might help doesnt hurt to through one on

When I first installed my ASP pullies, I had the crank pully on backwards and it caused the belt to scoot towards towards the block and get chewed up.

Might be worth checking.

i will give that a check and let you know, thanks
