Greatly increases belt wrap when switching to a smaller pulley.

If you are going to run a smaller supercharger pulley sometimes it makes more sense to buy a larger tensioner pulley. The tensioner pulley costs less than a new belt and is very easy to change using a 15mm wrench.

Our 3.5" tensioner pulley (stock is 3") will allow you to reuse your stock belt with a 3.4" supercharger pulley on the 3800 set up. It gives you more wrap on the SC pulley helping to prevent belt slippage.

Idler pulley

My experience with this item was satisfactory. It's an idler pulley with new bearing. Works as expected.

Supercharger Idler pulley

Much improved quality from the typical plastic versions I have used before. I will order another one for replacing the other idler pulley.

Pulley is great quality but no bolt...

The idler pulley is hefty and is much better quality than the factory plastic one that gets chewed up after some time. However its an issue swapping the stock bolt from the factory pulley to this new zzp unit. Zzp should have inlcuded a bolt to screw into the mouting hole on the ICM but otherwise it will collect dust for now.

Good quality parts

Much better than OE, these pulleys are much heavier duty than plastic, thank you ZZP.
