Definitely a great product. Very happy with this purchase. If I ever need another one, I'll definitely go with this same brand.

Very happy with this 1" spacer all in all. Fit and finish is good, price is reasonable, and comes with the necessary hardware and gaskets. The only minor thing to be aware of is that the sides and back are undercut on the outside to save weight and material. This is not clearly shown in the pictures. This is not a problem unless you want to very seriously clearance or 'port match' it to your manifold. If you clearance the inside opening aggressively you can end up through the thin side walls. I believe this to be a RARE problem but worth mentioning since it kind of surprised me. Most spacers are a solid casting that's cut to the inner and outer profiles. (Top down view) My Holley 750DP fit on the spacer and then on my Stealth manifold with no binding or range of motion issues right out of the package. The openings all lined up perfectly so no special clearance adjustments were required. I believe for probably 99 out of 100 people this spacer will work perfectly right out of the pack and never be an issue. Definitely worth buying if you need an economical true 1" spacer.

Installed between Edelbock intake and Holley carb to eliminate vapor lock caused by heat. Studs were too short so had to buy longer ones but product is high quality.

I HAVE NOW INSTALLED 4 OF THESE THEY ARE SIMPLY THE BEST! AMAZON SELLS THEM AT A LOWER PRICE THAN SUMMIT RACING. ALWAYS USE A MR GASKET 1 INCH SPACER!

This worked well to cut down the issue of my car vapor locking but the plastic one I bought does a better job.

Love it. It added the necessary clearance between carb and manifold to use a 50cc accelerator pump
