man don't make that mistake, i had the same mindset when i bought my coilovers, now i've gotten into endurance racing and it's going to cost me about $850 to get my shocks converted to remote res. style. if you buy them that way right off the bat it doesn't cost that much more than emulsion style. they will resale better than emulsions too.

if you are going with Fox's call up Poly Performance and ask for Tommy ....he gave me a freaking awesome deal on my shocks- WAY better price than anyone else and free shipping. Poly will also set your initial valving/tune and install tender coils, shafts bumps etc for free.

Hm, I dont see me doing any racing with this, particular truck but some good points to take into consideration none the less.

thanks for the tip on who to talk to also. Every little bit helps when your counting your pennies!!:cheers:
 
Just a Few things to add, Ive been getting into the Desert racing scene so ive been trying to learn all this shock stuff myself..

Bypasses - Do not help with head dissipation, they are just an external way to adjust valving based on shock position..

Remote Reservoirs - Will Help Prevent Cavatation, because the Nitrogen is stored in the res, and the Shock Body is 100% Fluid.

Air Shocks have no fluid, and will heat up pretty quick in the high speed stuff.

Air & Coil Over?? To me that add looks to be Mis Labeled add, its either Air, or its a Fluid with a Spring over the body. Right??

Dude, Air shocks have oil...
If they didn't, they would have no dampening and would be called a pogo stick :) They are basically an emulsion shock. PIC:

The coil/air hybrids are basically a threaded body airshock. I think the idea is to be able to run lower pressures and be easy to tune.

This..

They are a compromise between a real air shock and a real coilover shock. The benefit is tuning possibilities past a conventional air shock, and a reduction in the spring "swapping" of a conventional coilover. I'm not overly pleased with the performance of the CO air shocks, but they are nice and easy to tune.

I'd still just do it once and do coilovers.

Exactly why I'm not gonna waste my time and efforts by running leaf springs. I know what I want it at and with leafs the wheelbase isn't possible.


So with the 2.0 coilovers what kinda springs and what spring rates should I look at starting with?

you ever get a weight on the truck?
 
for reference I am running 14" 2.5 COs.... 10" 300 over 14" 350 and tender springs (triple rates). 5-6" up travel and about 26"s to the bottom of the frame with the 42s.

The Calculator on the FOA page was pretty useful when I set up mine. Getting close on unsprung weight is pretty critical.

X2 .. and remeber if you are gonna start looking at others spring rates, keep in mind angle of coilovers ( if it's compound angle ) and angle/long of links .. still will be guess but more educated one.
 
Ok here is my personal opinoin. The whole air/coilover shock is a flippin gimik. dont go down that road unless you like aspirin. The 2.5" body is nice and all but you have no need of that much dampening or cooling for the type of wheeling you do. You dont travel at a 120mph for hours and hours on end. Plus the 2.5 doesnt have the spring rate options that the 2.0's have. Stay with the 2.0 save some money, take advantage of the fact that the 2.0 is a smaller package both in diameter and length and they are cheaper for the shock and the springs too. 2.5 are for braging rights.
 
I haven't bought anything yet. Still be at least a few weeks before I can.

Thanks for the info nutly, In general it seems that air shocks are not desirable on anything..

Air shocks actually work really well. On a rock crawler or lightweight sand car they work great. Adjustments are easy, they mount easy etc.

Coil overs just give you the option for extremely fine tuning and less of the heat issue. Personally I wouldn't hesitate for a second to run some 2.5 air shocks in your setup. There is no way that with your setup running a 2.0 coil over vs a 2.5 air shock would give you any noticeable advantage. You would just spend a lot of time fine tuning your coil over and spend quite a bit more money. Living in Texas and the fact that its not daily driver really makes them a good fit in this case.

The advantages of coilovers start coming in with high speeds, jumping, huge temperature difference and heavier weights.
