Cliffs High Performance Quadrajets :: Qjet Carburetor Rebuilding, Quadrajet Tuning, Qjet Rebuild Kits & Parts

Carburetor services

Welcome to Cliff's High Performance
the quadrajet experts.

At Cliff's High Performance, we offer various performance upgrades for your Q-Jet. We have the experience, knowledge and the right parts to get the most out of your carb, regardless of the application.

Quadrajet carburetors were used by General Motors on millions of vehicles. Quadrajets are extremely flexible in their design and were able to be calibrated very specifically for each of those applications. Since the vast majority of these carbs were delivered on low performance vehicles, swapping out a Q-Jet that was designed for a 6 cyl truck onto your 450 HP stroker is not going to work.

Carb rebuilding alone often will not deliver the desired level of performance. That's the Cliff's High Performance difference. We build the carb specifically for your engines needs. We perform Quadrajet tuning that's tailored for your car. Quadrajets are very efficient carbs. With the correct Quadrajet specific tuning they have a huge performance potential. With proper tuning, Quadrajets provide users with the best of both worlds, mileage and performance.

In recent years, enthusiasts have come back to their cars factory carbs, the Q-Jet in particular for their high performance vehicle. With the rising cost of fuel and the high price of aftermarket carbs, it only makes sense to use an efficient, affordable carb. A well prepared Quadrajet that has been through Cliff's High Performanace rebuild and tuning process is the perfect choice for your Pontiac, Chevy, Buick, Olds, Ford or Mopar. Even for marine carb uses Quadrajets are an excellent choice!
