The Big Rig performance experts at Bully Dog Big Rig have done it again! For 1973-2003 CAT 3406A, 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 Stage 1 Billet Wheel Turbo Charger is an OEM replacement for trucks making from 400 to 625 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). With a quicker spool up and better craftsmanship than OEM turbos — the Stage 1 turbo is the perfect OEM replacement and is the best turbo charger for class 8 vehicles on the road today.

The only difference between Bully Dog’s Stage 1 and Stage 2 CAT Turbos is the exhaust housing. The stage 1 housing is a 1.32 AR and the stage 2 is a 1.45 AR. The larger housing on the stage 2 allows the same volume of air but it will be slower. It will run just as well as the stage 1 but with lower boost. If you have a higher horsepower rig, the larger housing of the Stage 2 will help you prevent over-spinning the turbo.

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 1 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.
