Torsion Bars

i want to lift my 88S-10 a little, and i just want to know how much i can safely tighten the torsion bars... i was hoping at least an inch and a half, just to give it more presence, and little more beef. any advice for someone is poor, and wants height???

Re: Torsion Bars

I jacked my to the limit and got two inches. Its about as high as a new ZR2. My dad works at a local chevy dealer and says it won't hurt anything but it will ride like hell. It still rides pretty good though. I put shackles on the back fron napa 18 bucks nice cheap lift.

Re: Torsion Bars

I don't like the idea of cranking the t-bars all the way. One, the suspension hits the bump stops on every rebound.
Second, (and more importantly) When the suspension is fully compressed it causes the t-bars to twist approx. 50% more than they would stock. This is eventually going to cause the bars to fatigue and begain to sag.

I think you would have a lot less to worry about if you stayed conservative and went an inch. I would save up a $100 and get a body lift, or just do a little fender trimming.

Just my opinion.


If anyone has any specs on the t-bars, let me know. I'd like to do a little math to figure out how much twist, max twist, ect. of the bars

Hit? Them tires rub. Rubbin's off roadin.

Re: Torsion Bars

Your absolutely right on the money. Ask Weasel, He's broken quite a few. Not to mention all that banging will tear out the ball joints and wear out those torsion bar mounts. Level it out with the torsion bars and get a 3" body lift since it's an old truck you can get one for around $70 at max. Tom

Re: Torsion Bars

If one did crank the torsion bars up, wouldn't it increase the running angle of the front cv joints? And if so, how far can one go and not shorten the cv joint life?

Re: Torsion Bars

Wrong there they don't go. The inter cv joints are a plung type, to move with the terrain, adjust to different conditions. And the ball joints they have a life time warrenty so guess you guys were wrong. I've had the bars cranked for two years and nothing yet buddings. O yeah by the way my dad works at a chevy dealer. And i asked the mechanics before i did it. One more thing with the torsion bars cranked they don't compress all the way. They are farther away from the bump stops not closer, and you should put bigger bump stops to so they don't go 50% more like a ZR2
has. And the factory recommends cranking the torsion bars when you add a plow to help the truck accomodate it. I don't think the factory would say that if it was going to hurt things. And a body lift isn't going to do [censored] for bigger tires your not even getting more ground clearance and the tires are still going to hit the frame.

Re: Torsion Bars

When you add a plow, you add weight to the front, which causes the truck to not sit level anymore. When you crank the torsion bars with a plow, it seems like if you were to crank them up just enough to compensate for the added weight on the front, the angles should remain exactly the same as no plow and stock t-bar setting. This is because you're not running it any higher than normal settings. Or is that wrong?

Another thing about a body lift, is that yes, you actually gain a little ground clearance (half the increase in diameter of the new tires from the old ones). How is a suspension lift going to keep the tires from hitting the frame?
