KIT INC (PLEASE CHECK MEASUREMENTS BEFORE PURCHASE) :
PLEASE LET US KNOW YOUR SWAY BAR SIZE AFTER PURCHASE Polyurethane 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. |

Description: | 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 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.
The tangential grease grooves in the heads of shackle bushes reduce the friction between the head of the bush and the shackle plates. The grooves store grease, which is smeared around the mating surfaces when the spring shackles rotate, forming a lubrication boundary layer. This has the effect of minimising head friction and reducing noise.
