Wagler Competition Streetfighter Duramax Engine | 2001-2016 Duramax

The Wagler STREETFIGHTER Duramax offers neck-snapping torque, with impeccable street manners, and is the ideal upgrade for light-duty GM trucks and classic hot rods alike. It was put through seventy-eight grueling engine dyno passes and intentionally pushed to the breaking point, just to find out where it is. Taking it to the next level, the Wagler R&D team is currently verifying real-world performance at Wagler’s private test track in Lyons, Indiana. Such extensive testing has given Wagler Competition Products the confidence to back the STREETFIGHTER Duramax with a 12-month/12,000-mile warranty.
