House of Horsepower springs

[memphis2857]

Anyone tried Richards progressive rate springs? Rod Overstreet says they are the greatest thing since sliced bread. I ordered a set of .45-.50 fork springs along with a 6.0 shock spring from him today and plan to try and run them for time being with stock valving. Thoughts? I also ordered one of those super sexy pipe and silencer combos.

I've been contemplating the same setup. I am about 2 hrs. from the House of Horsepower, so I might just drive down and pick me up a set of springs.

Hopefully some people chime in and post their thoughts, otherwise I may just wait for the ride report from you, Memphis2857.

Richard seems pretty knowledgable and approachable on suspension in general especially on the Sachs and marz. I think he will offer good assistance on getting the correct setup and is not in it just to sell you springs.

Progressive fork springs were used pretty widely in the mid-80s, etc. They aren't anymore... I am not going to piss in anybody's wheaties - but there might be a reason for this fact...

Personally i think the biggest reason not to use progressive springs is the problem with identifying problems with your suspension. depending on where you are in your stroke you will have different spring rate, and i am sure that will play havoc with trying to create good shim stack

The fork already has a progressive nature in terms of effective spring rate - the air volume in the fork decreases as you go through the stroke - as volume decreases the pressure increases - and setting oil level is used to tune this....

The rear also has a progressive nature due to the design of the linkage...

This is my personal experience - not theory... A progressive spring tends to go through the initial stroke of the fork *way* too fast and then you are into the "stiff portion" of the progressive spring. This is *very* unpleasant when braking hard and hitting braking bumps or in harsh terrain that gets you into the stroke of the fork...

Basically - somewhere in the stroke of the fork you will have the correct spring rate for your needs - and anywhere else you will either be too soft or too stiff for your needs...

It's an old idea that was dropped for a reason....

And see - I said I wouldn't piss in anybody's wheaties and I went ahead and did it anyway...

At certain lifestyle clubs you probably have to pay extra for that.

Hey! you said it.

Excellent. Just the info i needed! Now time to decide what "non-progressive" spring rate I need. I don't want to tackle shims just yet.

This exactly what the racetech suspension bible says (even though they sell progressive rate springs) but after talking to Richard and Rod they convinced me otherwise. I guess I have already bought them so I will put them in and see how it goes. If I don't like them I am only out $110

I'm no suspension guy by any means. I'm not even good at tuning it, but I can tell you I had a set of Richards progressive springs in my 50mm CC Zokes on my husky 165 and they were great.
