Icon5 Coilover Valving...

Ok as some people know, i broke a POS Bilstein C/O the other day..

Option 1 was to go through RCD... hell no its $300 for the whole assembly.. i have 750# Hypercoil springs... dont need the shatty 600s...

Option 2... go through Bilstein for just the shock, nope they were gay "you have to go through a vendor"... well it just happens RCD has tried to just get the shock from them before w/o luck

so it leaves me with

Option 3... Find other coil overs. Fox and King are nice.. but damn son $$$$.. So i went and looked at FOA.. $175 a shock, much better! I'll be getting 2 since i dont know how far behind the driverside shock is from breaking. The bilsteins from what i understand were 14.625" compressed and 19.125" extended, these are 14.25 and 20.25 so i think that will be fine... BUT as usual i ran into a problem.

The compression valve and rebound valve.. Do i need: zero, extra light, light, light/medium, medium or firm?

-Thanks

Problem 1: You probably can't run the coils from your 2" RCD's on the 2.5" F-O-A's - I assume that the RCD C/O's are using a 2.5 ID spring but you would need 3" id springs for the F-O-A's.

Problem 2: F-O-A's 3" ID coils only go to up to 700 pounds in a 12" and 650 in a 14" or 16". You can check but I think the max rates for 3" Hypercoil and Eibach are even lower for those sizes.

Problem 3: Check your clearances. I question whether the 1/2" larger diameter F-O-A shocks and coils will fit using RCD's mounts.

Problem 4: Longer extended length will probably mean that you'll need limit straps to prevent CV bind and ball joint damage. Without straps, the UCA's could also hit the top of the frame rails at full extension.

Damping: Your mounting points and travel are roughly equivalent to my Bilstein 7100s and they are valved 360/80, the highest compression and rebound that Bilstein offers in a 2" shock. Maybe that will help as a reference. Beyond that, any good suspension shop should be able to recommend a good starting point for valving their shocks to your app.

interesting for some reason i thought the RCD was 2.5" ? but maybe that was the coil number like you say.

Is that shock body OD or spring ID?

If the RCD C/O's are 2.5" body, that should help with a conversion to F-O-A's. In there regular shock lines, Bilstein doesn't catalog any 2.5" shocks but some of the ultra expensive 9xxx series are available as 2.65" bodies. On the other hand, the RCD shocks are custom made for them by Bilstein so I guess anything's possible.

RCD coils are 2.5" ID

i think motochris is a member here as well....i know someone from FOA is. IF you can make them fit, id talk to them about valving; thats their arena.

FOA coilovers are 2.5s so they need a 3.0" ID spring.

well if i need to buy new springs i'll just skip them.. it'll end up costing just as much

i'm contemplating just not buying anything and having my friend go get the axles from denver if i give him gas money. but then im worried i'll run out of money before i get all the parts..

I know how to valve shocks, but have never gotten too deep into the theory behind valving. I know people, and have gotten alot of help on my truck, but wouldn't feel comfortable doing one from scratch.

Besides that I HATE the way FOA does their valving... drives me nuts. What's "light" for me might be to heavy for somebody else... it's way odd... but I don't want to get into it with Chris again, so I'll shut up now.

If you want to see the practice of valving a shock you can check out these...

Don't think I have any King handy, but it's mostly the same.

Get them from a seller, eBay or otherwise, who will custom valve them for your app. The generic "average" factory valving is probably way too light for those 750 springs.

Also, think about whether you will have interference problems at the CV boots, etc. RCD coilovers use a strut on the bottom of the shock to position the spring up and away from the boot.

See if bilstein will give you a part number for the shock you need, I have access through a few different suppliers for bilstein, so let me see what I can do.

PM me or IM me when you get the part numebr and I'll let you know
