The SPE 2020+ GT500 Adjustable Auxiliary Idler consists of a precision CNC machined billet aluminum bracket and extreme duty double ball bearing idler pulley anodized black. Adjuster components & hardware are made of billet 304 stainless.
The adjustable auxiliary idler bolts to existing bolt bosses on the vehicle's supercharger snout and locates the pulley just to the left of the supercharger pulley, maximizing belt wrap and eliminating slippage. It is designed to work in conjunction with the SPE GT500 Blower Pulley System & is perfect to pair with 2.6” and smaller blower pulley. No modifications to the vehicle are necessary.
The Adjustable Aux Idler allows you to get the perfect amount of wrap with varying belt lengths and/or pulley sizes. The idler assembly ships fully assembled with the required fasteners and illustrated installation instructions.
I installed this at the same time as their pulley system and glad I did. It ensures the belt is not going to slip because it wraps around 270 degrees of the blower pulley. Made in USA which is important to me.
ABSOFUCKINGLUTELY epic quality and customer service! SPE IS TAKING OVER!!!!!!!
The fit and finish on the items were second to none. Install was VERY EASY and the adjustment works very well. Overall very happy with SPE and will do business with again.
I bought the fixed idler from PBD. Belt chirped. Bought adjustable idler from you guys because when I emailed for directions you were so much help! The adjustable idler had enough travel to eliminate the chirp and achieve 270 degrees of belt contact with the blower pulley. Great product! Love it!
Excellent product!! even that I'm using a competitor pulley its work perfect any kind of noise.
