Winter mods: whatcha got?

[BrianN]

I just looked at the Eibach spring selection and they only have 18" up to 225lb. That is why they suggested (2) 16". Oh, and DS, I just happen to have a pair of 10" Fox shocks that match my front 12" shocks, but it is too late Now!!! Well, maybe with my next mod session.

I am glad you reminded me of the preload option. I just removed 50 lbs (for comparison) from the corner sprung weight and got 122 primary. That comes to 200/300 springs.

What is the max dimension from the spring perch to the adjusting collar?  I would use a combination of springs that will allow the spring assembly to be just slightly loose when the adjuster is fully backed off or even screwed down up to around an inch. This is your zero preload point. If possible use a tender spring that is 2" (or maybe even shorter yet depending on where/when your crossover collar will hit) You want your crossover collar to come into play at around 50+- percent shock travel.

 From what I see ,I would use a corner weight without concern of a passenger of 470 (540-1/2 of passenger of 70=470) and a 3.5" to ride height that will make a good starting point of 135 spring rate that would be a 340 main with a 225 tender.  After that the valving will be the most important thing you will do.If and only if the bottoming out cannot be avoided with the stiffest valving should a higher spring rate be done. You will be cussing the valving tuning but it must be done and a complete set of shims is best to have on hand. That is not cheap.It's also the only way to "get it right" without compromises.

Don't discount the nitrogen charge either. It adds a significant preload to the equation at ride height .  As the shock extends it becomes insignificant but at ride height it will  raise the car ride height when charged.

Thanks for the suggestions and info, y'all. I had to put my phone away tonight and do my taxes, so I will do more measuring tomorrow night.

Don't forget to get a gallon of oil and perhaps a couple spare wear bands.

I would like to learn how to tune/rebuild shocks for myself, but I will have to do some serious homework first. I have started reading articles, etc. But, as usual, I tend to get confused!!

There's really nothing to it.

rebuilding and revalving fox shocks is very easy to do. brianN you are more then easily capable of doing so yourself.

[BrianN]

It is sitting on springs! Car only: 4" to ride height, zero preload, 13" ground clearance. So I have 7" of up travel to limit straps. Accutune didn't want me to put bump stops on the shafts because it damages the seals if used too much. So I will come up with something to use as bump stops. 200# primary and 300# secondary. I will probably end up adding preload. Valving will be another issue. Then on to front shocks.

looks like a great starting point. looking like its close to dune ready as well!

I am just waiting to get my truck back so I can leave. If all else fails, I will rent a truck to pull the trailer. When will you be at the dunes?
