Tensioner Pulley & Idler Pulley Kit
2015 & Newer Dodge Challenger & Charger Hellcat, Trackhawk, Demon, Redeye, and other supercharged SRT applications
Important Note: The tensioner pulley included in this kit fits the early-style Hellcat tensioner only. This tensioner is manufactured for Dodge by Dayco, and bears the part numbers 68222744AD and 2228133. If you car uses the smaller Dodge tensioner, which says 'Mopar' and 'Canada' on the front, with the part numbers 53011558AA 15909, no tensioner pulley is available to fit that tensioner.
Because of the length of time required for machining, assembly, and QC, we need 2-3 weeks from receipt of the order to ship these specialized pulleys to you.
This kit includes two heavy-duty idler pulleys: a double-bearing grooved pulley to replace the OEM steel unit used on the belt tensioner for the supercharger drive, and a double-bearing smooth idler pulley to replace the OEM unit directly beneath the supercharger pulley.
These CNC-machined billet pulleys are machined from solid 6061 aluminum, and each is fitted with two high-speed, high-load, double-seal roller bearings. As shown, each pulley includes a matching bearing cover and the appropriate stainless steel socket-head fastener. The rear side and belt surface of each pulley is hardcoat anodized in black to resist wear and maximize supercharger belt life.
These pulleys install as direct replacements for the original pulleys, with no special tools required, and no belt change is necessary. The included tensioner pulley is slightly oversize to optimize belt wrap at the supercharger pulley. Both pulleys measure 76mm (about 3") in diameter.
In the standard configuration, this pulley set includes the (2) pulleys: the one grooved pulley to replace the pulley on the tensioner arm and the one smooth pulley to replace the idler pulley directly beneath the supercharger. A third smooth idler pulley is available as an option in the kit to replace the other smooth idler pulley located lower on the engine.
Please note that image 3 (above) shows an early production (not yet anodized) version of the tensioner pulley.
Each of these pulleys is available separately if desired. Please contact us for details.
