Proven to Leak
I consider myself to be pretty skilled with tools, but these seals made me feel like an idiot. These leaked on both sides and failed state inspection immediately. The inspecting mechanic recognized the problem--Leak Proof Seals--and suggested that I use factory seals. I replaced the so-called Leak Proofs with genuine Honda seals that same day, and have had no problems in the year+ since.

Beats Honda OEM seals...
I bought new bushings and seals for my 86 1100 shadow last year from the dealer...waste of $100....they leaked worse than the old seals...bought a set of leakproof seals and no more leakage...the wife's Virago needs the fork seals replaced...I'm going with LeakProof again!

leak proof pro moly seals
I bought parts unlimited seals for my Goldwing and they were so much nicer than these.

They don't have a metal core and are almost like foam.

I just can't see how these are going to be as good as they
say the dust boot is hard plastic with some sharp edges and have casting nubs all over.

I might use these on a bike I was selling but not on one I intend to keep

Who knows they may be perfect but to hold them in your hand and compare them to others, not impressed

They leak
Put these on my old 1984 Honda Sabre with only 15000 miles on the odometer. Installed them. They were fine initially. But they started leaking after they were used alot. Once i saw they were leaking. I pushed down on my forks repeatedly with a fair amount of pressure and i could see it ooze out. About 1/2 teaspoon a cycle.

My forks aren't worn down. And no grooves in them. Smooth. So not sure why these would leak other than cheap seals.

Not recommended.

Another great purchase
Seals and wipers very comparable to OEM. Correct fit without alterations. Good price and very quick shipping. Couldn't ask for much more.
