Rancho 2-1/2" lift yeilded 5"

Ok so a while back I ordered a set of rancho coils that were supposed to get me 2-1/2 to 3 inches of lift. Now I've put them on and I got a total of 5-1/4". So I'm now wondering how much more work I need to do to be road worthy. I'm thinking I need a slip yoke eliminator and or new CA and adjust them for the right angle. The sway bar links seem pretty short as well. The track bars are only shifting the axel about 1/2" - 1" side to side. Any thoughts would be appreciated.

Thanks for the input. I measured both coils at rest and it yielded 4" from the oem specs you told me about. So as I drove around today I was getting a little vibration from ~35-45, then it would go away. So I'm going to make some 1" spacers and drop the skid plate and see if that takes care of it.

There are some other things you need to check out. If it was 4" springs that were sent with a 2.5" lift, your shocks are wrong, your front axle may be off center, you will need different bump stops, and you will need different lower control arms...there is more to a lift than just springs. You need to figure out if a complete 4" lift was sent, or just wrong springs.

No lift was bought. I was putting the lift together myself. I found that the coils I purchased we HeavyDuty coils for a 3 inch lift. They expect heavy aftermarket bumpers and winch to be on so that's where I'm getting the extra inch from. I am worried about the shocks. They have about an 1" to 2" before they are stroked out. Do you think that is enough? I have adjustable track bars on order. Plus a aftermarket bumper to put in the rear which weighs about 50lbs more than stock.

I put the same Rancho 3" HD springs on my old 98'. It yielded over 4" of lift. I had 31's so I fixed that soon after with 35's.

If you are able to return the springs and get a complete kit, I would choose that route. You are in a costly situation that would involve alot of guess work to fix. You currently have shocks that that are not matched for your lift height and driveline angles vibes that won't be corrected with a simple TC drop.

Did you align the front after the lift? That's a must. Set the toe in to 1/8". It takes under 10 minutes to DIY. The alignment being off and those puny tires will make it feel squirrelly.
