Product Details

High Velocity Heads SS4500-2AL High Velocity Heads Super Sucker Carb Spacers

High Velocity Heads Super Sucker Carburetor spacers give you the midrange and high end benefits of 4-hole and open style carburetor spacers into one spacer. Originally designed for Winston Cup engines and eventually banned because of the performance advantage they provide. By increasing the velocity of the air as it transitions from the base of the carburetor to the intake valve you get more HP. The change in efficiency is so dramatic you may even need to make a jet change to the carburetor to maintain your air fuel ratio. Available in both aluminum and plastic, aluminum is for Circle Track or Street and Strip engines and plastic is for Drag Race only applications. Made In USA

Good price , easy order, and free shipping so I thought why not give it a try. Just in time for spring oil changes on lawn mower and tractor.

Fast & easy


The first product I received was incorrect and they were very timely in getting me the information I needed for the return. No hassle what so ever.

Fast easy ordering awaiting delivery

We had a few questions. Like how to pay with Amazon which didn't come up. Also we live in a small town. We put in the home address and added the PO Box Number since our town is too small for home delivery. But mostly we negotiated it ok.

Had what I needed and easy check out.

Fast and quick ordering. Thank you.

so far so good, Will i get an e mail with a tracking number once shipped?

Fast shipping cheapest I could find, easy to deal with, great product

Ordering so far has been easy
