Level Front of TJ for a Plow???

Hello:

We have a 2000 TJ w/ a 6 auto. Pretty much stock with 31's. Just put a Meyer 6.8' plow on it and the front end is resting on the snubbers when the plow is lifted. With the plow down it seems to have dropped an inch or two as well. The MFG says the system weighs about 400-425.

The Jeep is going to be used as a spare vehicle and to plow a small lot at our shop. Prob not going to lift it but we're seeking some suggestions to level the ride to stock with the plow on and without making it ride like a dump truck when the plow is off.

Some have suggested air bags and I thought I saw someone had recomended a higher rate front spring. Has anyone tried any of these? Does anyone have any better suggestions??

Thanks in advance.....

I swapped out springs from, I believe, an XJ or WJ (sorry, don't recall - guys on here will chime in with which are interchangeable). Thicker and gave me 2-3" increase in height. Easy swap.

I have 2" BB (plastic pucks that are place on top of the springs) and that seems to work well with my TJ. It still saged with the plow up but didn't hit the bump stops. You should be able to get a pair for around 50 bucks.

I'd go for airbags installed inside the front springs. Airlift makes them like at Air Lift Company Air Lift 1000; Coil Spring - WRANGLER (97-06TJ) which has a 1000 lb. leveling capacity.

Did yours sag with and without the plow up as well? Sounds like the pucks and the bags might be the way to go. Though I'll need longer shocks for a 2" lift right???

Any feedback on how the bags worked?

Airlift's airbags work well and they've been around and making them for many years. I installed a set of them into the rear of my old '89 Cherokee to level it out so I could tow my rather heavy power boat without the headlights lighting up the sky. It was a very easy installation and inflating them is just like inflating a tire. They come with the same type of fitting a tire uses so you can use nearly any air compressor to inflate them for plowing, one valve inflates both sides simultaneously. Deflate them when you're done with the snow plow, pretty simple.

Sounds like Air Lift it is. Now just have to decide on manual or wireless onboard pump.

Does anyone know of a 2" spring spacer lift that uses stock length shocks?? May want to do a small lift as well but dont want shocks that ride like a dump truck. Was thinking maybe white KYB's.

Thanks

A manual pump is good enough and certainly cheaper, it doesn't take much to get those two small air bags inflated. Any cheap tire pump can do the job in just a minute or two.

A 2" lift is a 2" lift, one brand won't be able to use stock length shocks whille another brand would require longer shocks. It really depends on your current shocks since they or may not be ok with just 2" of additional height... but more than likely they would be ok though there are no guarantees.

Stock shocks will work fine as long as you keep the jeep on pavement.

Air shocks in front work well. Monroe MA763 or Gabriel Highjackers 49216. You will need a minor mod to your shock tower to accommodate the airline or you can just zip tie it to the shock.

Not sure what your going to choose but there was no sagging without the plow.. And I have a winch and aftermarket front bumper. Air bags are def a good idea if you want to keep the stock height... And no, I didn't change shocks Witt he 2" lift...

You had stock springs and no sagging with the bumper, winch and plow mounts???? That doesnt seem possible. Our TJ has about 182K on it and its sagging a bit with just the mount on it. The mount only weighs about 30-40 lbs max.

We ordered air lift air bags and we're prob going to put a 2" lift with spacers and stock style shocks for the hell of it so we can get it off the ground a bit.

Does anyone know how to find out the springs rates on the front springs? We hae a customer thats replacing some front springs off of an 05 Rubicon TJ/LJ. I would think they have to be a bit stroger than our current TJ.

Thanks

The '05 Rubicon springs would work well on your TJ... they do have a slightly higher spring rate.

Rubicon springs are not much different from normal TJ 6-cyl springs...in fact many models all shared the same springs.

i'd recommend V8 ZJ front springs. they are actually a higher rate.

I just posted over on Jeepforum a few days ago with a few different spring options, but for something like a plow that is temporary air bags are the answer.

We installed the Airlift airbags and it seems to work great. Brought it up to level and it only drops about an inch when the blade is up at 50lbs in the bags. Now it needs shocks and I think we need to replace the alternator with something a bit bigger. When we actuate the blade all the lights dim and the volt gauge drops a bit.

I'm assuming there is a stock 60/80 amp on it now. Any idea how to tell? I see that 117 and up is available,

Thanks

Most 4.0L engines came with the 117 amp alternator unless it was a really stripped down model. Having a/c almost guarantees the 117 amp alternator.

Try removing both battery connectors and wire brushing them and the battery posts until they are bright and shiny, then securely tighten them back onto the posts. Bad battery connections are common and they can cause the problem you describe.

Just put a brand new battery, Interstates biggest at 800 cca and the posts and cables were pretty clean. It doesn't do it as bad as the old battery, but it still seems to be slow with the defroster blowing and the plow going.

It does have AC. If I'm at 117 already it looks like I'll likely need bigger.....

Make sure your battery cables are not rotting from the inside out and that the connections at their other ends aren't bad. That your lights are dimming in view of your last post is a little surprising.

We run dual batteries in our dump truck at work and no longer have issues with the plow dimming the lights... we've got a 9'8" Boss VPlow on that so it takes a lot of power to lift it up. When running a single battery that thing nearly turned the lights off lifting it up. lol

Lights dimming when the pump is actuated seems to be pretty common in many plow applications, though I cant find any that actually reference what the amp draw is. I'll double check the other connections as well though.
