Rear Coil Spring - Decision Time

[RL Lemke]

I just did a test of air pressure and the height of the bottom of the hitch. At 0 pressure it is 19 3/8. At 5 PSI it is 19 1/2. Then it is incremental small increases. At 30 PSI it is 20 1/2". I don't think that any sort of big lift is available. Just the ability to compensate for increased hitch and back end loads. I'll try this again when the 4Runner is loaded with luggage and passengers in back.

thats cool. i not expecting it to lift the rear end much. I just ordered a set from Summit Racing. They should be here this week. I just want more control while towing my Toy Hauler. The rear bottoms out alot, and i think this will help alot.

effect on xreas?

would xreas be compatible with these?

Yes. I have a '04 SE with XREAS.

For those of you in Canada...
Just ordered the Air Lift 1000 kit #60809 from Canadian Tire for C$130.00. Could have gone a cheaper route via a US order but would have had to bug my friends with shipping and picking it up in MI.

Sorry to resurect this but...does anyone know once you have cut the bump stops, how hard is it to replace them with new stops down the road if you wish to return it to stock?

Thanks,

An update...

Installed the Air Lift kit. Didn't disassemble the rear to do it. Tucked them in between the extended coils. Excellent results for a low priced mod. Tightens up the rear end. This will definitely help the on-road feel with the utility trailer. Put the valve in the same place as Bobby (thanks for the idea.) I'll play around with the pressures to see where to inflate them for daily hauling.

i fould 10 -12 to be the best. I had to remove the coils. I love the set up, the rear drops about 1/2 of a inch when i connect my travel trailer.

Thanks. I had the same drop so thats what I'm hoping to correct with this setup.
The hardest part of the install was cutting the passenger side bump stop while inside the coil because of the lack of room (next to the exhaust.) Used a hacksaw blade in a single handle holder (not sure what you call this tool.)

Update...

I've had the Air Lift installed for about 2 weeks now and found I had a very slow leak. All the connectors on the valve and air bags are brass but the tee connector is just cheap plastic. Decided to swap it out with a brass tee with compression fitttings (not the nicest weather right now to be working under there so this was the most obvious down and dirty thing to do.) Hope this solves the issue.

Update: Issue resolved.

would this mod solve the sagging I have or would I need something more heavy duty? heres a pic of my problem, its actually not as bad as it looks in this pic, i'm kinda on uneven ground

 

[Kmvreter]

MercuryEvo,
I'm no expert at heavy towing but something about your pic tells me you should have a weight distributing hitch setup. I just use my T4R periodically for a light utility trailer. The airlift bags help because I can't always balance the load so I end up being tongue heavy.
For you, be careful how much you are loading the tongue to mimimize the squat. You want the tongue wt. close to max. but not over. Move the car back on the trailer until you reach max. Then if you go with the bags they should help "firm up" the ride.

 

[AmbideXtrous]

Kmvreter is correct. A good weight distribution hitch will help with squat by torquing some of the weight to the front end of the 4R. Airbags will also firm up the rear end. If you don't have the weight distribution hitch then I would start there first. Also moving the car rearwards will help but at the risk of increasing sway.

I agree and watch for a sway issue when balancing the load. Keep the tongue at max weight. I would get a sway control wt. dist. hitch with a load like that.
Search for trailer towing because there are guys on here that have discussed them.

I just installed the Airlift kit. No suspension disassembly required. I found that a sharp serrated blade will take the jounce bumper off in no time. As has already been mentioned, the passenger side is a bit trickier since the track bar mount and the exhaust are in the way. All said, a pretty easy install.

rear coil

hello...

I have the rear sag in my 95 and want to put it back to level, if not a little higher in the rear.. I am kinda a newbie so still learning..

I have heard good things about the OME's and Moog... But at the same time a little confused on what to get.. I see 1", 1.5", etc.. How do I know what to get?

NOt looking for anything major as far as towing.. I looked into the AIRLIFT 1000 but some say it provides more towing but DOES NOT lift the rear end...
Can anyone help out on this one?

Thanks in advance

The Airlift would take the sag out. It would lift it an inch from the cirrent, sagged level. It won't lift it much beyond whatever the '95 looked like on day one. It does allow for great load compensation flexability and capability. I hooked independant right & left air lines for right to left levelling as well as taking the sag out. (That setup does hurt articulation minimally.)

Your best bet is to define your goal. If you want to lift beyond stock for looks/big tires then aftermarket springs would be best. If you want a cheap pretty good fix for the sag and the ability to adjust for weight the bags would be great. If you don't need load levelling capability new stock springs or OME's might be the way to go...

It's very hard to suggest pros/cons etc until you clarify the mission and the budget more

Bumping this thread for "imprttuner88" who asked about it.

will this work with the OME or toytec coil?
