Lifting/improving a 92 troop

Postby kipkasper » Fri Apr 21, 2017 12:38 pm

Hey guys,

I'm a pretty solid gumby when it comes to this kind of thing, but I've got a buddy who's lifted his taco recently and it got me thinking. My trooper is great, I've made it in to plenty of rough places and don't really have any issues with clearance of performance off roading with it stock, however, it is a 25 year old vehicle and the suspension is fairly mushy. If I hit a divot in the road I feel it, any kind of successive impacts are bad news, you get the picture. Is there a way to "spruce" up the suspension for around $500 or less? It's got 230k on it, so I'm not psyched on putting loads of cash into it, but a smoother ride would indeed be nice, and I think it would look good if it rode an inch or two higher as a side effect. Ride is much more important though.

You won't need to spend that much! Yes, the stock springs are very soft, so some OME coils for around $170 (you have 3 choices of lift/load rating), adjust the front torsion bars to match, and you will love the ride. Also wouldn't hurt to replace the sway bar bushings with polyurethane, really tightens up the handling and only costs about $50. Now get an alignment to fix the camber after the lift and you are still under budget.

So you're saying to lift the front just tighten the torsion bars? No new shocks needed? It's the front end that seems especially mushy.

First, look for worn components especially the ball joints and tie rod ends,

Next, check the shocks.

If you have money left over, maybe this post will help. viewtopic.php?f=1&t=87959

Mario's comment above is good advice if your front end is "mushy".

But to answer your question, the ride height for the front IFS is adjustable. There is an large (27mm) adjustment bolt at the back end of the torsion bar. You can adjust several inches up or down from stock without much issue. While new shocks wouldn't hurt as a general thing, they aren't required for this sort of lift because you aren't changing the amount of suspension travel, you are changing where you are riding within that travel. In other words, the lift is exchanging down travel for up travel. Taken to the extreme, the ride will suck and even be unsafe without enough down travel available for the suspension. But you can lift a couple of inches this way no problem.

If you look at the thread I gave you, you will see a link to a post by Nasty that provides lots of options for rear coil springs. Raising the front is just a matter of tightening the torsion bars. The issue is that you are trading off lift for suspension travel. IMHO raising the front more than 2.5-3" is not advisable because as Swede said "the ride will suck and even be unsafe without enough down travel available for the suspension."
