Rotrex Supercharger – LS Truck (’99-’14)
Price range: $4.999,00 through $5.075,00
Bolt-On Supercharger kit for GenIII and GenIV (99-13) LS truck motors | support 500hp to +1.200 hp | No cutting or permanent modifications
Centered around the C38R-122 Supercharger, this kit is THE boosting solution for your GenIII/IV LS truck or engine swapped vehicle. This setup can provide up to 26psi of boost and +1900CFM!
We’ve designed this kit to be as robust as possible, with a 10-rib belt, and a configurable idler and tensioner system to ensure that you’ll never have to deal with belt slip, regardless of how much power you’re making. Not only that, but the configurable idler and tensioner system also allows you to change the supercharger pulley size, without needing to change the belt – that’s right you can go from 500 to 1.200 hp with just* a pulley swap! Configuring the belt system is as easy as it gets, with clear inscriptions and a detailed install guide, that will tell you how everything needs to be set.
The kit mounts to factory mounting points, and there’s no irreversible changes required. The kit comes with everything required to mount and drive the supercharger, including brackets, pulleys, belt, lubrication system and of course the supercharger itself – only thing that isn’t included is the ATI Super Damper (partnr 918628). We’ve intentionally left fueling, charge air plumbing and tuning be up to the installer or end-user, as no two builds are the same and to allow favored brands or products to be used.
