Worked like a charm!

Very Happy with this. Good Product

Line up the manifold well enough to put in the rubber band style seals. No instructions so hopefully you now what your doing.

5 by

not worth it. the plastic rings get warped when hot making it leak. use the original O-ring seals that works

5 by

great for adapting o-ring heads to bands

5 by

Nice kit. Comes with gasget combos for o-ring and band type Shovelhead intake manifolds. They're always a pain.

Works great

Another useless product that didn't fit. I even paid extra shipping to get it faster because I really needed it. What a disappointment to find out it didn't work. It's just a piece of plastic.

5 by

Nice fix for leaking o-rings.

5 by

The spacers are great. adapt your intake to the rubber band style and clamp down hard. Get rid of the crappy rubber O Ring !!

5 by

Worked well for my application, to convert to using the rubber band type manifold seal on my old o-ring seal type shovelhead.

5 by

Does what it's supposed to with an assortment of plastic O-rings to fit under and "repair" damaged O-ring flange or simply better seal with manifold "Band" seal.

5 by

always fit just right.

5 by

definantly solved my damaged o-ring flange sucking too much air, sputtering and backfiring hesitating problem

2 by

Not being a Harley mechanic for 30 or more years, I could have used some kind of directions as to which adapters to use for what carb/manifold.
