Product Description



The Big Rig performance experts at Bully Dog Big Rig have done it again! For 1989-2003 CAT 3406B, 3406C, 3406E, C15 and C16 truck owners, the all-new Lighter Aluminum Billet Wheel Turbo delivers performance, reliability and fuel economy. Bully Dog Big Rig’s 80mm Stage 2 Billet Wheel Turbo Charger is an OEM replacement for trucks making from 600 to 900 horsepower. Engineered & Manufactured with Bully Dog’s renowned quality, this turbo features improved torque and fuel economy as well as lower EGT’s(Exhaust Gas Temperatures).

A vitally important component to a vehicle’s overall performance, the turbo charger affects power output, fuel economy & throttle response. The turbo charger that’s running in your truck is a factor in its efficiency — if it’s less than the best, then its efficiency is not optimal — and that affects your experience on the road, especially during long hauls. If the throttle isn’t responding effectively, you aren’t getting that extra power when it’s needed. What’s more, you’re wasting fuel — and that’s money out of your pocket. So choosing the best turbo charger for your rig is nothing short of crucial. Bully Dog Big Rig’s Stage 2 CAT Billet Wheel Turbo is proven on the road, both in performance and longevity. It typically costs less than an OEM replacement — AND there’s no hassle of a CORE charge.
