I am looking for 4 coil over shocks with or without resivore .where is the best place to start looking ???Gerry Thanks for any help.

The search button, start there.:rolleyes:

got mine from mike, great guys there, beat any price out there.

I also got mine from Mike @ Baja Concepts, very helpful and great prices.

long travel shocks do not come without reservoirs according to Brett at kingshocks.com

I called around today, to try and cut the cost of coilover shocks.

Things I learned:
Dual rate springs are used because the shock generally has more travel than one single spring
Remote reservoirs are used because of the volume of fluid displaced in a long travel shock, not for cooling
Spring rate is calculated by adding the upper and lower springs together, then divide by 4.
Example: (300+300)/4 = 150

Does that all sound right?

What's the going rate for them there shocks?

550 to 650

I too got my 16" Sway Aways from mike at baja concepts and yes he is a great guy to deal with, but do you realy need that expensive of a coil, as far as I know he only sells sway aways kings and I think bilstin. if you want a more econo. coil that will do everything you probably will need, except if you are desert racing I would go with the doetch tech coils. the spring are like half as much and the shock is only like 199$ with the mounting hardware. I love my sway aways but I dont know if I'd do it again. I think I got like 2400$ into getting them and playing witrh the spring rates.

Im a long way from using this info, but just out of curiosty, are the D Techs rebuildable?

Dude who were you talking to? Remote reservoirs are used to house the floating piston. Spring rate is calculated by product/sum.

We sell SAW coil overs. $219.00 for 2"-16"travel emulsion shocks.

the guy I talked to said that he builds all the king shocks. I was wondering about the floating piston, but he didnt mention anyting. Just repeated that the res is not for cooling over and over. :confused: I asked him why my fox shocks on my sled dont have to have reservoirs on them, and he just said that is was for fluid volume. He just said that with out it the fluid would just turn to cola.

Ok dude, this guy sure knew alot for being a shock builder....:rolleyes: In a nonemulsion shock a floating piston is used to seperate the shock fluid from the nitrogen. This is to eliminate the emulsification of the shock fluid or cola effect as you call it. In most cases the floating piston is located in a reservoir. This is to minimize the overall length of the shock. However, you can locate the floating piston inside the main shock body but this will require a longer shock can/body in relation to shaft length. Now when you use a reservoir you inherently will use more shock fluid which will help cooling if you are doing 100mph through the desert. This can be helpful because as the fluid rises in tempature its viscosity may start to change. OK get it....? Now emulsuion shocks do not have a floating piston seperating the nitrogen and shock fluid. That is why these IMO are ideal for just rockcrawling. Have you ever felt the weight of a full remote reservoir? As competition gets more and more compeditive more and more people are looking for ways to save weight. A little here and there will add up. The fluid will not emulsify, at least to any noticable degree, going as slow as rockcrawlers do. I hope this help out a bit. It's time for bed, I have to go to the desert tomarrow..............:)

The doetch tech coils are fully rebuildable and at that price I think are custom valved to your specs.(as best they can) I never herd of SAW coils but I would check them and the Doetch Tech coils before I get some expensive ones. My next prodject is going to have some doetch tech coils, w/non remote resivoir. Unless your cycling your suspension fast and very often, I dont think you need remote resivoirs.

I HAD THE DOECHTEC COILOVERS THERE JUNK THE FIRST TIME OUT ONE PUCKED OIL ALL OVER . THE OUTING I BENT ONE IN HALF GO WITH THE KIGS ,SAW, OR EVEN BETTER BILSTEINS CALL BOB AT ROGGY ENT OF MIKE AT SHAFFERS OFFROAD

I was told that the reason for a remote reservoir is to make up for the volume displaced by the shaft when the shock is compressed.

Product Sum, so its (300*300)/(300+300)=150 so In that case it worked out,

A three spring set up would be (1/300+1/300+1/300)^-1=100?

Then your effective spring rate will always be less then your lowest spring rate.

(800*100)/(800+100)= 88.8

Is that correct PIG?

I've had Doetsch coilovers for a couple of years, I never bent one without bending a link or busting a rod-end first... they work fine.
They are rebuildable.. unscrew the the cap (or both caps) and pull the piston and rod out, replace the seals and fill it with oil.

Pig: Thank you. Thats basically what I was trying to get at. (about not having to use a remote res.)


So who will sell me a long travel emulsion coilover shock?

I will likely never drive my truck at high speeds (over 25 mph) for more than very short distances, and can deal with some shock fade. I just want a shock/spring setup that offers more controll than what Im running now. (Rancho Leafs and RS 9000's) I want to be able to hammer the truck over obstacles and get the front end off the ground once and a while, with out breaking my theeth out, and damaging my suspension. I run alot of washed out dirt trails, swamps, and as much rocks as I can get my tires on.

LOL, I have felt the weight of a remote res, but it was fox remote res for a snowmachine/snowmobile, and only weighed about 12 oz. :D We dont have any deserts up here in Alaska other than the ones covered in snow, so I have zero experiance in long travel coilover shocks. I have, however, re-valved my fox coilover shocks on the front and rear of my Thundercat. (170 hp snowmachine for those not in the know) I used valve specs for snowcross sleds published by Arctic Cat. I have also changed springs on said shocks and experimented with different rates, wire diameters, tension, ect.

Below is what I mostly drive in...broke a stub and hub in the 60 just before pic was taken (was almost out too damn it :D )

bingo
if the piston didnt make up for the displacement of fluid ,the shock would have harder damping the further it travled in the compression stroke .

it allows the shock to have uniform damping throughout the full stroke . and also increases the amount of fluid thus helping to keep the fluid cool .
