Rochester Quadrajet Power Piston Service Kit – Adjustable Part Throttle APT 1979-Up

Got a Rochester Quadrajet carb from 1979 or newer?

This little service kit is just what you need to tune it up.

It's the adjustable power piston kit, made for the APT (Aneroid Part Throttle) models.

You get the metering rod retainer spring, the power piston collar, and the power piston spring.

It's a mix of steel and plastic parts, made right here in the USA by Ace.

If your Q-jet is running a little off or you're rebuilding it, this kit helps dial in the part-throttle mixture.

It’s a small but crucial piece of the puzzle for your classic ride.
