      1948-84 intake manifold seal kit.

      This kit is much easier to install than the pain staking factory O-ring seals. Install time was around 10 to 15 minute's. The kit also come's with 4 band style manifold clamp's which I think help's to provide a really good seal.

      Seal kit manifold kit

      Very good. Always a bit of a struggle to fit manifold and seals in place, but the seals are firm and fit well. Dual band clamps work well too.

      tite seal

      after 8 months of trying to cure an intake leak thought i would give these a try, anyway i ordered a set of these, within a few days it arrived, took the o rings off and put these on, went on really easy, used the supplied clamps , tightened everything up and started the bike expecting to still have a leak, lo and behold no leaks !, bike runs perfect now, done over 300 miles with these seals and still no leaks. excellent product wish i had bought these sooner. cant recommend these enough, will be ordering another set soon,bike is a cone shovel

      Good for leaky o-ring

      I have a 74" knucklehead with o-ring conversion (done wrong), they ******* in the inserts too far and there was a huge gap between the intake spigots and the manifold. This will HOPEFULLY cure the intake leaks I've been having. Fits real nice and doesn't look too bad.

      Tite Seal for sure

      I got these to address vacuum leaks, the two little clamps per seal work great, they’re just kinda annoying to get on.

      Tire Seal kit

      So far, so good. Unfortunately it’s December 9th in northern Illinois which means I haven’t given the seals a good test, I’ll get back to you in the spring.
