Swapping out to a smaller supercharger pulley is the easiest way to add power to your 1999-2004 Ford Lightning short of a tune. However, the smaller you go, the less contact area the belt has on the pulley. This leads to the belt slipping.
Luckily BilletFlow devised the solution by way of these 100mm Idler Pulleys. If the belt is slipping, then you are not achieving full boost. These idler pulleys will not add power themselves, but the elimination of belt slip allows full boost which is where the power increase comes from. These two 100mm Idler Pulleys offer a simple bolt on installation. They are black anodized for long lasting good looks. Plus, the new billet idler pulleys allow for reliable operation, unlike the stockers.
Had a problem with an order/quality issue. I put up a review stating so, and was contacted by Mike Linley, who was soooo nice and sooo professional, I almost felt bad about my review !! I felt the review was necessary because of bad welds/paint. Mike explained that they had a particular issue with that supplier and they had changed suppliers because of it. I must have mistakenly got an old set. (upper/lower Control arms-Foxbody). Mike asked a few questions, and was Sending me an updated replacement set while we were on the phone.!!! This is what I wish all Vendors would do; no arguments, no blame, no B.S. !! This is why LateModel stands out as an upstanding company, and backs up their products with AWESOME Customer service.
