    Is there anyone who makes a coil spring conversion kit for a 73-87 4x4. I want a better ride and off road performance for my truck. I want to keep it lifted 6" and run 35"-37" tires. It's a daily driver so ride quality is important too. Most of these trucks are very rough once lifted. Any suggestions on kit manufacturers or trucks that would make good doners?

    Steve Frisbie (Moo) and Stephen Watson (Ord) have both done this, no kits available that I know of at this time.

    Find a 63-72 Chevy 2wd truck for a donor. They use a rear coil spring suspension and should be easy to adapt to any 73-87. You could use the factory mounting brackets, trailing arms and aftermarket coils to get the lift you want.

    Check out some soft Prerunner type leafs from Deaver spring or National ( both in souther Cali). They are pricey but ride really nice and will still cost less than coilovers.

    Hey, DBLAZER, Not including axles, What would something like that run? Do you have any pics of the project you are working on?

    Your goals are easily achieved with leaf springs. Don't waste your time with coils.

    Well, I can think of a few good reasons.
    <font color="red">#1 The Flex </font color>
    Yes I understand that a leaf spring set up can really work. Mine has for years, really well. But I think I can get a little more twist out of the coils. You can always go to a longer spring, but that defeats the next point I have.

    <font color="red">#2 Approach and departure angle. </font color>

    You can only take off so much angle when the leaf springs have to stick out front and rear. You gotta have the frame there to mount them to.

    <font color="red">#3 WHY BE NORMAL. </font color>

    Well, this may come as a shock to some of the sheep around here, but it is OK to be different . It is OK to build your rig a little different from others. We don't have to build rig that looks like Steves, or built like Stepehn Watson. (Not that I am saying anything bad about there rigs, I love them both. They are very cool) I am just saying it is ok to want something different. And coils are a very cool UPGRADE.

    Oh ya, with the fourlink set up axel wrap should be taken care of also.

    By the way, as it stands now, we are not designing a bolt up kit for this. The set up we are running onmy rig is going to push the rear back and the front very forward. Without some major MAJOR reworking of the frame and body work, this setup will not work on a stock rig. We can build something for you if any of you like. Rocktek is located in Grapevine Texas. Anytime yall want to stop by and see some of the work going on in the garage drop me a line.

    I foresee the possibility of making a bolt on rear kit, if there is enough interest. The biggest detering factor in the link and coilover suspension upgrade is COST! None of the parts are cheap. The coilover shocks alone cost around $600.00 each. Quality heim joints large enough to handle the job on the link arms are $50.00 each. Johnny joints cost $40.00. The big question is "Is it worth it?" For me "yes". I plan on having and wheeling my truck for many years to come. The ride quality is unbelievable( I drove it to Moab and back, 2300 miles round trip) and you have to work to get a tire to lift while wheeling. I did manage to lift a tire a few times in Moab. I also moved my front axle forward and the rear back so I now have a 110" wheel base.

    I agree with ya. The heime joints we are running are 1.25"
    About 53 bucks a pop, the DOM tubing runs about 7.50 a foot. Not cheap. I am not runningthe coil ocers like you, I went with reguler coils, a little less expensive.
