How to lift my Comanche

I have a 1991 Comanche and I was wondering what I need to lift my truck 2 or 3"? For around $200, I want to do shackles in the rear and coil spacers in the front but I cannot find anything online! Any help will be greatly appreciated

The only shackle out there that will give you a true 2-3" lift is the IronMan4x4 ones, I'm running them on the back of my Jeep right now and they're beefy as hell. For the front, search for Cherokee 2" coil spacer (I would not go any higher than 2" on the spacers for safety reasons). There are MANY companies out there that make the spacers.

Why is this the only one? What's so special about them?

The issue is every other shackle I've seen was made for the Cherokee. The Comanche shackle is ~1" longer than the Cherokee shackle. You would need to find a 2.5" shackle for a Cherokee to get the 2" for the Comanche (every 2" the shackle is longer than stock gives you 1" of lift). The IronMan4x4 shackles I have is set at a hair under 4" longer than stock Comanche shackles when set to the smallest setting, which yields 2" of lift for the Comanche.

If you want the true adjustment from 2-3" for the rear, IromMan4x4 makes the only true adjustable shackle. Every other shackle out there that is "adjustable" is just another set of holes drilled to give you two fixed lengths. The IronMan4x4 shackles has a screw type adjustment (like on the adjustable control arms) letting you fine tune to the ride height that you want.

Front coils from a dakota will do a 3 in lift in front and take a Cherokee leaf pack and mate it with your mj leaf to make a lift or do axle flip will do 4in

The SOA will net around 5.5" of lift, not 4".

I just finished a soa on the back of mine and I believe it already had hefty leafs on it. It seemed to raise it 8-8 1/2 inches total. I now am looking into a long arm for the front. The problem is that I am doing a frame up and don't have the weight of the engine, tranny, transfer case or anything on it to determine what I really need. I guess I will wait until I finish painting the engine compartment, install the engine,ect. to see what it will take to even it out.????

8-8.5 sounds a bit off. The springs don't have much to do with the lift, it's the axle tube diameter plus 2x the tube to spring mounting distance. This is around 5.5" with a D35 and D44. Measure from the center of the axle to the bottom of the flare. 26" distance is 6.5" (keep in mind that the truck has a 2" rake so to level it out, the front needs to be around 8.5"). SOA in the rear and the IronMan4x4 shackles all the way in netted me 6.5" lift, for comparison.

For the front springs, I love the Rusty's 8.5" lift coils. Ran them on my old Cherokee for about two years then slapped them on my Comanche. Even being about 4 years old now, they still measure 8.5" lift (center of hub to bottom of flare) in the front. That's even with the extra weight of the Chevy 350, custom 1/4" front cross member and winch added. For the long arms, that is a lot to do with personal preference and what you plan on doing with the Jeep.

I chose to build my own true 3-link setup since nothing on the market satisfied my needs. The most common, and generally the cheaper setup, is the y-link setup (or radius arm, all matters who you talk to). I had the first gen Rusty's setup on my old Cherokee (rubber bushings all around) and it flexed great for a "4" link, drove great on the street also. If I were to go with another off the shelf y-link setup, I would do T&T Customs due to the fact of the beefy belly pan and the frame end joints are offset up to let you slide off obstacles easier. RockKrawler has a 3 link that is beefy but the frame side separation wasn't enough for my needs and I don't like how it mounts below the frame (again, personal preference on that part). I'll leave it at that before I start going into geometry and all that fun stuff of suspension systems.

Thanks everyone for all the help! Iam thinking about the grand Cherokee coils for the front but what kind of leaf springs will I need in the rear to lift the truck 3 inches? And will I need anything else?

I'm running XJ 2" shackles and MJ 2" add-a-leafs. Which gave me 3" on the rear.
