I have already done it to my 1990 FLHS. It is not as simple as it might seem, so look through my Suspension THUMP thread.

There's one big difference with ride str-8 and yours, the axle adjusters help but you also need to beef up your axle spacers on the inside of the swing arm, if you look at ride str-8 he made new axle spacers that were much wider on the side that touches the swing arm to help spread the torque out and to keep from pinching the metal, I'd look around at a machine shop and see if you could get the spacers made and you should be good to go, I know guys with over 80,000 miles on 01's with ride st-8's design without issues

Here's the original axle adjusters


Here are the better ones which give support inside the swingarm fork.


It's the next best thing to upgrading the swingarm if it hasn't cracked or broke yet.

I have to give credit to Howard and Motorcyclemetal.com for bringing this to my attention when I bought some shocks from him.

I see what you mean. Although the inner part is about the same there's a shoulder on the spacer.



Edit: After seeing them close together in the pics I can see the Ride Str8t units are much better.

BoomerBob, his are stainless steel but I think the axle adjusters are fine that you bought, it's the spacer I would change, if you can't get them made another thought is I know some guys who went to Lowes and bought galvanized oversized 3/4" washers had it welded to the spacer then removed the amount they added on the other side, you only have to worry about your pulley side of your swing arm because on the other side your caliper is up against the swing arm not your spacer

It's funny you should bring up the caliper. After reading this thread I went out to the garage to take a look since I have the bike up on a lift with the bags off right now. I could see the caliper side was ok. The sprocket side could use more meat on the spacer up against the swingarm but it's not too bad. Maybe because it's a 99. I dunno. Still; I'll keep this idea with the washers in mind because it's a good one and a simple way to make it better than it is. Thanks!

Thanks to everybody here for their help. It is great to have a place to go and hash out some of these issues.

So I finally talked to the GM at the dealership and he told me he was not going to help me out because of 2 things. Number one none of his techs would ever overtighten anything and 2 my bike is an 01 and when bikes get older, you know, things break.

When I told the owner of my Ford dealership that he couldn't believe it. We are constantly negotiating with costomers over 'coincidences'. As a tech for 18 years I have seen many coincidences, they happen, but we always end up taking it in the shorts to help with customer satisfaction.

If only all the dealerships felt that way we'd be in good shape. Unfortunately they are far and few between.

found out today that mine has a lowering kit. (bought the bike used...know nothing about these kits)showed the broke off end to a tech at the dealership while there for my parts. he said take those off..the added length caused it to break. gonna find/make a bushing and an outer washer for the pulley side that is as wide as the swing arm itself.my question is should the axle adjuster have any up and down slack in the tube? those new type looked the same as far as the that goes. could a person weld spacers on top and bottom to fully support the inside top of the tube or would it hold without.

The only requirement for the adjuster is that it can slide inside the swingarm tube, so it does its job when tensioning the belt and aligning the wheel. But that is one of the weaknesses of the design. From 2002 when Harley changed the swingarm design the axle goes through a solid piece of metal, instead of hollow tubes. Its one reason I upgraded my old bike with a later swingarm.
