I'm having suspension issues....shocks to be clear. I have the full adjustable rancho's in the front. The truck is a 1990 ext cab with the 3.0 and a 4" lift. My problem is the rear shocks when I bought the truck...they are pretty much brand new generic truck shocks. They are terrible...it use to be a guys hunting rig and it carried a in bed camper. I've noticed when I have a load of mulch or firewood the trucks OK but without weight in the back it scary. On the highway the small bumps of overpasses throw the rear all over the place...it's super soft and bouncy. Will getting a set of rancho's for the rear solve the problem? What shocks have you guys had luck with? Any recommendations for shocks that work well with a lift and 32/10.5/15.

PS it's 4wd 5 speed and the rancho's are rs9000xl in front

I wouldn't doubt they are blown out. It could be that the shocks on it are too short. You said you have a 4" lift. I pretty well always get me some longer shocks when I lift a truck more than about 2.5". It could also be due to the type of lift you have. Add-a-leafs or helper springs will really stiffen up your suspension making it flex less when a there is little load on it. Take a good look at the way it is lifted if you didn't do it yourself and inspect your shocks. Shocks simply stabilize and slow the travel of your trucks spring suspension. If they are blown out, just replace them with some that are designed for the extra height. The Ranchos should be fine. If the shocks seem to be working and the truck is lifted using spacer blocks, spend a little more money on a quality shock designed for a lift like a Blistein or OME. If it has an extra leaf in the spring pack, your issue may be more with the suspension being too stiff and you may want to rethink your spring setup. You said it was "super soft and bouncy". I'm betting you just need some better shocks that are designed for the lift.

One more thing just to be safe. Check the torque on your u-bolts back there. I have seen them loosen up after a few miles and cause major issues that could end up getting somebody hurt. I work with log trucks every day and I always check the u-bolts a week after replacing them and I always find at least one of the nuts loose. Probably not the case with yours but you're going to be under there anyway and better safe than sorry.

I personally like the bilstein 5100 series shocks. They are very good quality for the money.

I couldn't remember the model number. Those would be my preference.

yeah i just blew a set of pro comp es3000 because they were for stock height and optimal travel area was surpassed, the shock was over extended. i didnt do my homework and it cost me, luckily not too much.

We need a little more info. When you say the rear end is all over the place, do you mean the rear is so stiff that hitting bumps seems to make the wheels jump a bit, or do you mean that you wiggle and jiggle for a while after the bump? If its the wiggles and jiggles, consider a nice stiff shock. A good gas shock will cure that. Not a fan on ranchos for road manners.
