These specially formulated, high quality Polyurethane Bushings are designed to create suspension solutions for better stability, handling, and control, in both on and off road applications.
Better road holding
More responsive steering
Longer service life of suspension components
Constant straight line steering geometry
Increased tyre life
Many Front Wheel Drive vehicles do not have provision for wheel alignment correction, and as the vehicle’s suspension softens with age the vehicle begins to wander or steer off in one direction. Fitting replacement SuperPro polyurethane bushings will help reduce the premature aging of a vehicle’s suspension components by removing the excess compliance in the suspension system and reducing the NVH.
SuperPro - A Technological Innovation
Polyurethane Material
The specially blended Polyurethane used in SuperPro products has specific mechanical properties that make it extremely successful in its applications. The combined properties of extreme resistance to abrasion, low compression set, high tear strength, and a resistance to oils and solvents makes SuperPro ideal for most automotive applications. These properties lead to a resilient product that is highly versatile in its various applications.

Steelwork
The crush tubing is an integral component of the suspension bushing system and is necessary for free pivoting. The crush tubes are made to precision tolerances to ensure precise fits are maintained. All SuperPro tubes are made of Steel and are Zinc plated for corrosion protection and appearance. In some applications SuperPro incorporates end knurls and hardened tubes to provide positive location. Where required, SuperPro products provide precision machined steel shells to allow the installer to quickly and easily replace worn components.

The Double Helix
The double helix design feature has led to marked improvements in SuperPro products. The double helix is used in two applications - firstly on the inside of the bush, and secondly on the outside diameter of the crush tube.
The first design of the double helix is used primarily on shackle bushes to provide a region for grease to travel along. This allows a boundary layer of grease to form between the inside diameter of the bush and the outside diameter of the tube. The double helix is extremely successful in greaseable shackles as the grease can travel from the center of the bush along the helix and out to the grease grooves in the head of the bush.

Knurling
Knurling is used to enable unrestricted pivoting of the polyurethane bush around the crush tube or any other mating steel surfaces. The knurling has inherent design advantages - reducing the surface area of polyurethane in contact with the crush tube, which results in less frictional force being developed. The design of the SuperPro knurl bore combined with the integral grease retention lips, keeps the lubricating grease intact for the life of the bushing, and eliminates the necessity for periodic re-greasing.

Bullet Grooves and Voiding
Bullet grooves are incorporated in the design of SuperPro bushes to allow for variances in control arm or spring eyes. The voiding and bullet grooves also allow for the transgression of displaced polyurethane into the volume of the grooves as the loads of normal vehicle operation are applied. Even though polyurethane is in a solid form when it is manufactured into bushes, its unique properties enable it flow in a manner similar to a liquid when loaded. The action of the bush flowing into its voids prevents the generation of noise, vibration and harshness within the bush and its mount. |
