Can anyone comment on the ride quality on adding a perch collar? I am considering it just to get the truck level or at least not quite as much rake. However, I don’t want to screw up the ride quality. Are there any negatives to doing this?

I ordered this one Proto JC497. It is adjustable from 2"-4.75". It is supposed to be here tomorrow sometime, I will let you know if it fits.

996Turbo - did this spanner wrench end up working out?

Wanted to order one and try adjusting on truck by spinning the lower threaded "shock body".

The bigger the perch collar the worse the ride. I've got mine cranked pretty far to clear 37s (probably 3")and i'd say it's 20% stiffer than stock, but it's also not nose diving.

If you are adding any collars </=2" you aren't going to see much change.

Thanks for the info. I’m thinking I am going to wait for the Geiser progressive springs at this point, rather than go with a perch.

I will most likely change mine out when those arrive.

I personally am not a fan of the CAS. You have to bleed the nitrogen and install a schrader valve after installing the CAS. I started out at 200 psi like the instructions called for, but I might as well have been driving an F-550 with the tires over inflated. So I reduced the pressure down to 150 psi and that helped, but I still wasn’t satisfied. I bought a new set of shocks and the RPG adjustable collar and I love it. Works and rides a lot better and much easier to install. No need to bleed the nitrogen.

I guess I was a good boy this year, Mrs. Clause was really good to me and suprisef me with a set of Fox 3.0’s. Hopefully I’ll have these installed this weekend.

So you're on your 3rd set of Fox 3.0s already?

The spanner fits, but you can not adjust it with the shock on the truck. There is no way for the top of the coil spring to rotate.

hey Galan

Sorry to hear you had a bad experience. From the multiple times we spoke on the phone about 37s and UCA and other mods the rough ride was never brought up to my attention where I could have helped. Our system could easily be lowered down to decrease preload and achieve the height your static collars provided. The psi is an added benefit for anyone who plans to check it or adjust it. Also this is the only way the shocks are rebuildable currently without Fox recharging the shocks. I’m sure You will love the 3.0s . If I can help with anything in the future I’m all ears.

Best regards,
