Revavling Shocks... - Honda Prelude Forum

Mugenlude · 10-31-2003, 02:50 PM

Who has experience with revalving shocks? I have talked to Billy (thanks), and I know that Vince had his Tein's revalved to factory specs. I'm going to have my Koni's revalved this off-season and I'm looking for any input that is avaliable. I'm only planning on revalving and shortening, not going dual-adjustable. Anyone have dyno-plots? How about shortening of the shocks?

DR, bdb, Corey, anyone else???

I had mine done at ProParts/Tripoint in CA in January of 2001. Total cost was about $600 including all parts, labor, and shipping (this was just a single-adjustable revalve). Turn-around time was 2 weeks, but that was mostly luck, since they weren't too busy at the time. Koni NA had a 5 week turnaround, but were ~$75-100 cheaper.

The main guy at ProParts, Jim Leithauser, has since departed and now runs/co-owns Bimmerhaus in Colorado. Not sure of the quality of ProParts' work currently.

BTW, I have the dyno plots lying around here somewhere.

You got them revalved for the stock springs to race in DS correct? Did you have them shortened? Did you ask for anything specific when you ordered them? How are they for street use?

Pork Chop · 10-31-2003, 03:23 PM

Yep, DS (actually, it was GS at the time). I didn't get them shortened.

The only specific thing I wanted was to increase the low-speed compression. That's the important one for autocross. Overall, the rebound ranges are a lot higher than they were before and the compression (high-speed) is a little bit higher.

On the street, they're a little harsh. Big bumps feel fine, but you definitely notice all the little bumps and ruts in the road. I'm still on the stock springs, so it's still relatively soft. It is definitely noticeable by my passengers though.

Go on Honda-tech.com and contact user "CRX Lee". Lee works for Koni North America. He is probably one the best sources of knowledge about revalving Konis in the US.

Hmmm...Jason, I'm thinking about doing this to the rear, since I'm getting higher rated coil springs for next season. Since mine is a daily driver, I was considering buying a new Koni set for the rear, and have them revalved already.

Andrew, thanks for the tip...I may ask him a few questions later this winter.

Yep, that's who I worked with, and who I suggested Jason contact. I believe he's already talked to him.

Yeah I have breifly talked with Lee. He is at a trade show right now and due back next week, but I plan to get back in contact with him then. He did give me the number of this Tech. Department, but I would rather just deal with one person.

Prices I got were the following:
Revalving = $100/shock + parts (~$20/ea)
Dual-adjustable = $250/shock
Shortening = $72/hour (hour/shock is the norm)

I didn't inquire about the turn-around time, I'm not really concerned because I don't need them until next season (April around here) and I have another suspension setup.

And regarding shortening. It was mentioned to me by both Lee adn Billy that Civic shocks are shorter than the Preludes and are an option if they are revalved for the Prelude, this would save you the shortening labor ($72/hour), but obviously you need to purchase the Civic shocks.

So you'd save .... nothing.

i'm glad you found that information on having the shocks shortened. I've been thinking about having it done for my 3g, and if it's that cheap, I'll almost certianly have it done over the up-coming off-season.

I'm pretty sure you can't just get the shocks shortened without having them revalved/rebuilt. So you would have to figure ~$120 each for revalve/rebuilt, plus the $72/hour rate. So you are still looking at $200 per shock.
