Does anyone know if you can get heavy front spring for a tj?
-
You might want to explain what you need a bit more.
Oh, welcome to the board :wave:
-
I have a snow plow for the winter and its a little heavy for the stock springs.
-
Man I have been searching for a while for something. My warn 9.5t makes it nose dive as it is. might be able to get some air bags, or overloads over the shocks.
-
Excuse the dumb question, but nut just use some coil spacers? Or would that be too much?

PS: I love leafs! If you had a YJ, you could simply add a leaf!
-
Get a pair of Rubi springs?
-
Use Grand Cherokee springs.

I added a 1" spacer up front and fixed that!

i would think that unlimited rubicon springs would have the highest spring rate...
-
I know they sit an inch or so taller.

Old Man Emu makes heavy duty springs for front and back. They usually sell them in a lift kit with nitro charged shocks, but you may be able to just buy the springs. I would also look into a set of ACOS -adjustable coil over spring lift...these let you fine tune the necessary amount of lift to keep you rig level. If I had a plow I would also look into Rancho RS9000 adjustable shocks as well. You can set the front for a stiffer ride when you plow and softer when you wheel, or whatever you prefer. I have not seen an air bag suspension for a Jeep yet.

You won't be able to level the Jeep with the large snow blade on the front. It will take some work when you install the blade and run that during the winter, but then once the blade is removed, the front will go up due to the weight loss. The blade's weight is also so far ahead of the axle/spring that it acts as a twisting weight as well, pulling like a torque arm. This also reacts to the rear axle by lifting the rear pivoting off the front axle.
V8 Grand Cherokee springs should probably have the stiffest spring rate stock from Jeep. However, the unloaded height may not be equal or close to equal to use in the TJ stock coil. Spring rate is the amount of weight the spring will carry per inch compression. If the spring was 100#/in, then it would compress 1" for the 100#s, 2" for 200#s, etc.
When you add the blade to the front of your Jeep, measure the before and after install height of the coil. You may only need to add another coil spacer on top of the coil.
I run Rubi Unlmtd coils on my 4cyl TJ and they gave me less than 1" lift overall. This is due to the spring rate difference between tired old 97 coils vs 05 Rubi coils. I've added ACOS to the front to help level the TJ as well. With a 2" poly spacer in the back, then adding winch up front with bumpers, etc. I used the ACOS to adjust the front height and level the TJ.

Thanks for the info!
-
try to fit air shocks on the front will do everything you want
-
You have to be careful of using air shocks. Basic shocks are not designed to carry weight. Air shocks are designed to cary limited weight, but it really depends on the mounts. Without mounts, the shocks can not carry the weight.

I had some air bags in the rear. They worked good for a while but started to leak and I had to have them replaced twice because they wouldn't hold the air. The bags leaked where the brass fitting joined the rubber. they all leaked in the same spot so its got to be a manufactures problem. For the rear where I had the bags I made a plate to mount inside the spring and mounted some coil overloads there. They work great but are very annoying, I have not welded them to the plate yet so when I get some heavy travel they will catch the bump stop or factory spring and pop and make cool noises. I do not recommend bags with all the trouble I had.
-
There are companies making airbag kits that replace your coils, a buddy of mine runs them on his Rubi, I believe it has a 4" height adjustment range controlled from inside the cab.
-
has anyone seen an airbag kit for YJ? my thought is if i drive it in the city and hwy to have it lower and lift it when i go offroad - i have no clue about airbags so let me know if this is a stupid question too. I'm also thinking that i might get higher clearance when needed and not compromise the ride quality (stiff as it is with only 2.5'' lift).
-
Airock makes the replacement system for TJs but it can't be used on a leaf spring vehicle. Thats a real nice setup but very $$$$. IMHO there's a lot of little things to go wrong with that too, like height sensors and stuff, but overall the kits are supposed to stand up to hard wheeling reasonably well if not pretty much trouble free.
