GM 604 Crate tapered center venturi carburetor spacer, SS4150-604. Specifically designed to increase torque for the GM 604 crate motor.  At just only .650” -5/8" thick aluminum, This spacer will also work on any engine running a 4150 style carburetor needing more bottom end and midrange torque. The SS4150-604 is one of the most effective carb spacers we have developed to date! Increases on the race track, and the engine and chassis dyno have been outstanding! You can expect to see a 6 HP gain, 8 lb. /ft. of torque, a flatter torque curve and a flatter fuel curve. Made in the USA.

Helps drive off and top end. Makes 5-8 more pounds and 6-9 HP (chassis dyno) over standard 1.00" HVH spacers

Super sucker carburetor spacers are the most effective carburetor spacers ever developed. Super Sucker carb spacer also properly distributes the air/fuel mixture to the manifold. Improvements in the throttle response, drivability, top end horsepower and torque are commonplace when using a Super Sucker.


Designed by Joe Petelle at HVH over 15 years ago for Sprint Cup engines, this spacer will increase air speed from the base of the carburetor to the top of the intake valve, pulling more fuel from the carburetor, the Super Sucker will require a change in the size jet currently being used. E.T. is reduced as much as 1/10 of a second and lap times reduced as much as 2/10 of a second.
