ZZP Stage 2 Belt

SKU: ZZ-BDL1776-6R

$39.99 Sale price

Regular price $39.99

This belt was designed for use with GM's original stage kits which come with a 3.1" pulley. Running pulleys smaller than this works because of the Cobalt's tensioner but there are things to keep in mind.


 

1. A smaller pulley means the belt isn't as tight because it will have more slack.

2. A smaller pulley has less surface for the belt to grip

3. Smaller pulleys produce more boost, which in turn requires more HP to turn the blower. This additional HP increases the chance of belt slippage.


Ideally, this belt is used with a 3.1" pulley. A 3.0 is quite fine. As you go smaller problems can arrise and it's recommended to use our adjustable tensioner instead of the smaller belt. Another option is using our larger tensioner pulley with the smaller belt. We have seen belt failures with nearly all 2.7 and 2.6" pulley users who only run a smaller belt. We have seen many failures with 2.8" pulley users as well.

Just what I needed!

I bought this to fix belt slippage and partial boost. The previous owner had a STOCK length belt on the motor with a GM stage 2 Pulley. With THIS belt, the car maintains full boost in WOT conditions, with no slippage, great price.

ZZP BELT FOR COBALT SS/Sc

Hi I have an 05 SC with a ZZP stage 2 1/2 from ZZP ( 2.9" pulley, injectors, tune, and header and exhaust, cai) old belt worked fine for a while then started squealing like a fat pig. I ordered the ZZP belt because it was cheaper than the GM and I've always been pleased with ZZPs products for years now. The belt works great. The car is a tiny bit more responsive and I believe works better with the ZZP pulley than the GM belt. Thanks again for the great deal
