I have to change the anti-Roll bar link rods on my A2 1.4 petrol as the boot on one is deteriorated slightly and was an advisory on the last MOT. Made exclusively for Seriously Lotus in Europe (Looks exactly like the genuine Lotus part). Link rods are subjected to massive shock loading – more so on increasingly pot-holed roads. 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. Was: £23.54. There is another benefit of having adjustable anti-roll bar drop links, and that is their use in the practice of corner weighting. Here we discuss why they could be the next essential bit you need for your anti-roll bars. In most instances the drop link is used to ensure that the load is orientated correctly, and to bridge the gap between the anti-roll bar and the connection. 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. Over time, the sway bar link ball joints wear out. Anti-roll bars are usually fitted to the front and rear suspension systems. Disconnect the drop links on both sides of the anti-roll bar from the suspension arms and securely tape them up. Anti-roll bars, also known as torsion bars are designed to resist torsion when a centrifugal force pushes the inside of the car up and the outside down. Another vulnerable group are the current generation of SUVs which often have longer suspension travel than conventional cars, but the link rods are often no more heavily engineered. As its name implies the anti-roll bar reduces the amount a car body rolls when cornering. Many cars also use a rear sway bar. Some cars have done away entirely with the rear anti-roll bar and engineered the roll stiffness into the axle beam. If one wheel drops into a pothole the link rod is subjected to a massive shock loading. This can often be quite large and drop links of up to 300 mm are not uncommon. Then when the vehicle has been corner weighted the anti-roll bars should be reconnected.

Anti-roll bar drop links are short connecting rods that link your vehicle’s anti-roll bar to the suspension wishbones or shock absorbers. Also you should change the drop links if the rubber boot is perished. Some other designs connect the bar rigidly to an axle. Begin with both lower drop links disconnected. Each link comes complete with two self locking nuts (correct fine pitch threads) The anti-roll bar only comes into play if the suspension on one side of the car moves but the other side does not. This is usually the case, on a semi-independent torsion beam suspension such as a VAG group applications with a rear beam axle. There is also the likelihood to wear the bearing more quickly and cause knocking if it doesn’t break it. However, if you try doing this with an original equipment link, which will usually not be adjustable, you will be connecting the anti-roll bars to the links with pre-load. Go for brief and careful drive over some bumps. 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 … 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.

Normally the ball joints or bushes at either end deteriorate and develop lost movement (play) which can be heard as a rattling or knocking noise. Basically, a sway bar is a metal arm that connects the right wheel to its adjacent left wheel; this manages weight distribution in the car while driving and keeps the car level while driving on rough surfaces or while taking sharp turns. £34.99. The problems arise when the car is cornered hard, as it will roll much more than expected, causing serious and dangerous instability. This only happens in two situations: 1) Turning right - not all the time and never ever when turning left.

The component helps to counter this movement and ensure the car’s body rolls less. 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. Click & Collect. First, install the upper end of the drop links onto the sway bar arms so the lever length is the same on both sides (the shorter the effective arm length, the stiffer the roll stiffness). 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.

Link rods (or stabiliser links or anti-roll bar links or drop links) connect the left and right hand suspension components to either end of a common anti-roll bar made of spring steel which is like a torsion bar running across the car. A sway bar increases the suspension's roll stiffness—its resistance to roll in turns—independent of its spring rate in the vertical direction. The part that connects the outer ends of the sway bar to the suspension component is called a sway bar link. 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.

A sway bar, also referred to as an anti-roll bar, is a length of tubular metal that is bolted to both ends of the front suspension. It is the job of the drop link to transfer the roll stiffness generated by the bar. The torsional rigidity of the anti-roll bar limits body roll which keeps your vehicle flat through corners. If the lever is shortened then the roll stiffness increases, conversely if the lever is lengthened, the roll stiffness decreases. As you are probably aware, connected to the end of most sway bars is a drop link.
