I'm not thinking there is a difference, but I figured I'd ask..

I bought a set of ASP UDP's thru Thunder Racing with my H/C parts, but the ASP is on back order and they have the SLP's in stock with only a $10 price difference..

SLP vs ASP?? I know SLP has the advertised taller belt walls, even though I've never really heard of any problems with belts walking off..

Thanx... I figured I'd ask before I told them to switch them for me..

 

Neither.

$400-500 for parts+labor for 7rwhp isn't the best idea. I'm running stock on my car.

 

^ I install them myself and paid $240...
