    I was just wondering what the advantage would be to keeping the sway bar on my truck. I have a 77 Chevy 3/4 ton long box - 6" lift, 35" A/T's, and I am swapping in a TPI 350 if that makes any difference. What are advantages/disadvantages of ditching my sway bar? Let me know. Thanks!

    Later,

    Of course the sway bar is there to help control sway in corners but while putting in a 6in lift I dissconected mine and have not noticed a difference, I believe this is due to the increase in tire width over stock tires. I thought about a disconnect kit but to tell the truth the thought of having to reconnect the thing is not too appealing to me, I am lazy after a day of 4x. If it is a concern then use it.
    I don't race around anywhere in the truck anyways. I do take off ramps too fast though if it is any consolation and I have'nt flipped her yet. Good Luck!

    I have a 4" Rancho lift and have removed my swaybar. The aftermarket springs are stiff enough to keep body roll to a minimum. Just dead weight to me, so I ditched it.

    I have 4" skyjacker springs and no swaybar. I can't even notice it except for quick sharp turns.

    Okay guys, I am thinking about removing my sway bar, so here's my question. On those few times that you have noticed it's absense, how bad was it? A sphincter tightening moment? Just a whoa, that was a little worse than normal? Skidding around a curve sideways? My truck spends a decent amount of time on SoCal highways, so it is a concern for me. Also, my grandfather drove racecars, and I'm convinced that heavy use of the stupid petal is genetic in my family.....[​IMG]

    If you drive in traffic, I'd say keep it and install a disconnect kit instead. You'll lose control easier without it.

    As someone said in his signature: <font color=blue>it's better to have it and not need it than to need it and not have it.</font color=blue>

    High speed corners can be kinda weird. As the truck leans side to side, it changes the distance between the pitman arm and the steering arm, which acts exactly the same as steering input. Then as the effective steering input changes, the amount of lean also changes, so it's a cycle. It makes the truck seem more vague in where it wants to go. If you push the truck into a curve at all, you find your hand wandering around a bit to keep it in it's desired path. The swaybar lessens that effect by preventing as much leaning. If you want to know what it's like without it, just pull out the two bolts that hold it to the axle and tie it the the frame with some wire and go for a drive.

    Almost all lift springs are longer than stock springs, so the factory geometry of the swaybar is not correct with them. In fact, you'll probably have a hard time getting the swaybar connected without having the U-bolt plates on crooked. This incorrect geometry prevents the front suspension from flexing and gives a rough ride and limited articulation. The swaybar disconnect kit adds another pivot point in the swaybar link, eliminating the binding problem and smoothing out the ride. So with a lift, you really only have two choices: A swaybar disconnect or no swaybar. For highway driving, I recommend the disconnect.

    You mentioned that body roll would contribute to the oversteer problem in corners in a similar manner to bumpsteer. Would cross-over steering without the swaybar eliminate this?

    Thanks

    I think that you're right, Brian. Cross-over steering should reduce oversteer with body roll in the same way that it reduces bump-steer. I've never driven a truck with the crossover conversion, but I hear that the difference is quite significant.

    I drove my 6" lifted 3/4 ton around for 2 years w/o any sway bar. I decided to swap one back on (with ORD disconnects, of course) and it made a 100% difference! For on-road driving, i will never go w/o one again. I used to drive this thing 75 miles a day to work and I could immidiately tell the difference. Better in corners and way better going over RR tracks!

    I have all swaybars on all three of my GM 4x4s removed. Haven't noticed a difference. Course, they're all lifted (6", 10" & 12"), so if you removed it with the stock junk soft springs, it'd probably be noticeable, but with lift springs it is not. Also, the crossover steering is incredible!! I could not believe the difference. My 12" lifted Sub with 39.5" Swampers will literally turn in a radius of about 1/2 the radius that it used to with non-crossover steering. Crossover steering is "THE BOMB"!!!

    I would hate to see what a 12" lifted Chevy steered like on the trails without crossover.

    Three lifted Chey's? We'll all pretend that we're not jealous :)
