It is useful to consider the loads we’re dealing with. Their job is simple: Provide resistance to minimize the vehicle’s body from swaying from side to side without adding significant harshness to the occupants or affecting the suspensions dampening system. This can often be quite large and drop links of up to 300 mm are not uncommon. The thicker the anti-roll bar the greater the impact. Our range is suitable for all sorts of vehicle, and features everything you need to keep things functioning as they should. This is usually the case, on a semi-independent torsion beam suspension such as a VAG group applications with a rear beam axle. The sway bar itself rarely gets damaged. The stabilizer bar links attach to the lower control arm at the front end of most domestic and foreign cars and trucks sold in the United States. These links connect the sway bar to the control bar with small ball joints - they’re important to keep an eye on. The sway bar is a thin, tubular piece of metal bolted to the suspension on each side … The anti-roll bar is a spring steel bar … Some other designs connect the bar rigidly to an axle. If this was 1 inch in diameter it would create 834 lbs roll stiffness for each inch of movement. I plan to change the front anti roll bar bushes for urethane ones in the next few weeks but it's going to have to go into my mates garage for this as they seem impossible to … These bars are always connected by a separate anti-roll bar drop link. Then when the vehicle has been corner weighted the anti-roll bars should be reconnected. Unfortunately in the aftermarket there are often cheaper alternatives which don’t last as long. The problems arise when the car is cornered hard, as it will roll much more than expected, causing serious and dangerous instability. The component helps to counter this movement and ensure the car’s body rolls less. The torsional rigidity of the anti-roll bar limits body roll which keeps your vehicle flat through corners. If one wheel drops into a pothole the link rod is subjected to a massive shock loading. If this occurs in cold and wet conditions when materials used in the ball joint part of the rod are in a more brittle condition, then the ball joint may become vulnerable to water and grit ingress with the inevitable result – total failure. Some cars have done away entirely with the rear anti-roll bar and engineered the roll stiffness into the axle beam. Each link comes complete with two self locking nuts (correct fine pitch threads) Anti-roll bars are usually fitted to the front and rear suspension systems. The upper end of the drop link usually passes through a horizontal eye on the end of the anti-roll bar, while the lower end is connected to the suspension arm in the same way, or by a vertical rubber bush and a through-bolt, or by a rubber-lined ball joint. Making it 1 inch longer brings the stiffness down to 605 lbs / in and shortening it by 1 inch increases it to a mighty 1218 lb/in. Made exclusively for Seriously Lotus in Europe (Looks exactly like the genuine Lotus part). By and large a drop link is used to connect the end of the anti-roll bar to the damper or a control arm. An anti-roll bar (roll bar, anti-sway bar, sway bar, stabilizer bar) is a part of many car suspensions which helps to reduce a vehicle’s body roll during quick cornering or over road irregularities. If we imagine that the original bar was just ¾ inch thick and had a fixed 6 inch lever it would have given us just 264 lbs of roll stiffness. This is why most semi-independent trailing arm suspensions still run a separate anti-roll bar. It connects opposite (left/right) wheels through short … Align the new bushes with the marks worn on the bar by the old ones. With the drop links connected I can't feel this play, even with a pry-bar. Here we discuss why they could be the next essential bit you need for your anti-roll bars. So it’s easy to see that by running a larger diameter anti-roll bar and running it in the stiffest position, the drop link has to cope with massively increased loads. On some front wheel drive applications, Whiteline may specify an additional anti-roll bar mounted on the axle beam and added in tandem with the existing bar. In most cars a sway bar link has two small ball joints at each end. … The car is an Omega. An anti-roll bar is a part of many automobile suspensions that helps reduce the body roll of a vehicle during fast cornering or over road irregularities. Disconnect the drop links on both sides of the anti-roll bar from the suspension arms and securely tape them up. Without them, the vehicle can often feel sloppy and unstable - and the first part of the kit that’s likely to show wear and tear is the link. Go for brief and careful drive over some bumps. There is also the likelihood to wear the bearing more quickly and cause knocking if it doesn’t break it. Link rods are subjected to massive shock loading – more so on increasingly pot-holed roads. For example, looking at front wheel drive rear suspension for a moment, a number of torsion bar suspension designs have an anti-roll bar that runs through the central beam, and is then connected to the trailing arm via a solid metal connection. Most of the time these links are adequate. The safety of the vehicle depends on the smallest and most vulnerable part of the whole steering and suspension system. The main purpose of the sway bar is to avoid body roll. When purchased in kit form, heavy duty adjustable drop links are often included making it a complete package, however many anti-roll bars sold do not come with drop links, and you are expected to use the original equipment link on the car. View a short clip of play detectors being used here The following categories apply to defects in this section: They enable you to set the length of the link to ensure the load is carried correctly, and set the length of the link to ensure there is no preload. Due to the fact that the sway bar is connected to the suspention, every time you hit a bump it’s not only the strut or schock that takes the hit but also the sway bar bushings and links. Our Pro Series Anti-Roll Bar Kit works great on all cars up to 1800 horsepower and up to 4000 pounds. Lets imagine a 3 foot wide bar with 6 inch levers. Receive Your FREE Whiteline Suspension Tuning Guide. Are uprated and adjustable anti-roll bar drop links necessary? Whiteline are well known for producing adjustable anti-roll bars and these have a number of holes formed in the end of the bar which enable the drop link to be unbolted and then moved. This means that the load will no longer be solely in the intended orientation (which would be North – South as you looked at a link). The anti-roll bar only comes into play if the suspension on one side of the car moves but the other side does not. Anti-roll bars first started appearing in cars in the 1950s, when suspension began to allow a greater degree of body roll in commercially … In certain cars, the rear end will also have stabilizer bar links.
