An overall great product with one drawback
After tossing between these and Speed Merchant's adjusters for a while, I decided to go with these. The price is right, the range of adjustment is good, the look is sharp.

And now, for the stupid part.

The upper portion is 10-sided 1-1/4" by about 5/32" tall. The documentation says to use an adjustable wrench, but shows pictures of what appears to be ChannelLocks being used. Why they couldn't just make it a 1-3/8" hex top to match the stock cap and be able to be used with existing tools like the MotionPro socket, I don't understand.

Other than that, they seem well thought out, well designed and well made. The ability to adjust preload by well over an inch on the fly with no need to open the forks and cut spacers is worth it. If you are interested in fine-tuning your suspension, put these on your short list!

Hard to install without damaging
They are manufactured with a odd ball 10point size head. This makes installation without marring the finish near impossible when following the supplied instructions.
Also they are made of aluminum not steel like the original HD caps. Extra caution must be used as stripping them while trying to install would be easy.
I chose theese over the competition because they had a greater range of adjustment. If I was to do it allover again think I would try the others. I am not looking forward to removing theese for the next Fork Oil change.
They are easily marred and don't seem to be the most durable peices.

Best available suspension mod
Installed these with a set of progressive springs on a 2013 sportster. No more dive under braking. Soaks up bumps like butter.

Great accessory, unless you plan on upgrading your shocks.
Recently I decided to upgrade the front fork on my HD 1200 Custom. I bought a fork brace, RSD Misano dust cap covers to match these pre-load adjusters, and Progressive Suspension monotubes.

First I'd like to say that these look phenomenal and match the Misano dust covers perfectly. I think both items would be a great addition to any harley front end.

Unfortunately, while they are compatible with stock suspension, they were not compatible with the tops of the monotubes, and i suspect a number of forward aftermarket shocks might give the same trouble. Hence I took the better shocks over the trick looking adjusters. Wish I could have both.
