    Antiroll Bar

    I am in the market for a antiroll bar and every company has their own design (splined or fixed, bearing or bushing). No matter what one I look at they are all a little different and I have heard some bad about cheap small splined bars, So what the hell one is a good one? Feedback plz...

    4 link or latter bar car?
    I can say that not one person that i know here in north Louisanna runs them, they have all tried them and took them off. most of my friends run door cars from low 5 teens to high 5's both latter bar and 4 link cars. Just curious as to why you think they it will help, it doesn't soulve chassis twist.

    An Anti roll bar/ anti sway can work pretty effectively on softer suspensions.
    When one side is compressed through weight transfer(a hard launch with body twist) or side ways(hard cornering) That compressed side will, through the bar, pull down the opposite side. Stiffer springs will not allow as much 'body roll' to actuate the anti roll bar action, hence the softer spring rates to make it work.
    Full bodied drag cars with soft rear springs and without a bar, will compress and create massive body twist actually unloading the left rear tire and over loading the right. Install and tune an anti roll bar and as that body mass comes down and twists , the bar forces the whole rear body mass the compress EVENLY and load both rear tires EVENLY.

    NASCAR Cup went to using soft springs and big sway bars years ago to 'lower' the car mass(center of gravity) on the corners especially on the speedways. I had been using them on MY oval track cars for 4 years before the big boys caught on.

    You want find anything in my area without one. Take 'em off and the front left tire will be 3 feet in the air and the right still on the ground.

    Have you had any problems with the aluminum arms Rabbit? Couple cars up here were cracking the arms and I also have talked to some guys that twisted splines on the spline shaft style.

    I don't see how they crack the arm's unless they have a bunch a preload in them. IMO they are probably trying to fix a set up problem with the anti roll bar.
    I do have some preload and as you can tell my truck runs on some pretty rough tracks. I have about 4"'s of full travel on the rear.
    Truck is probably close to 500 to 600 passes on it.
