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.
The Research and Development process for SuperPro products constantly gathers information and feedback to provide continuous product improvements. Superpro constantly re-engineers and tests its products on their own fleet of passenger vehicles and Four Wheel Drives.Cyclic testing is performed using specifically designed testing equipment, to offer valuable information on the life and durability of SuperPro products. Australia's diversely unique conditions provide the perfect testing ground for SuperPro products. Encompassing everything from extreme heat, dust, and harsh roads to race circuits, rally tracks, speedways and drag strips, SuperPro products are extensively tested in a variety of conditions to ensure the highest quality performance and reliability. SuperPro products are also further tested in the diverse climates of Africa, Asia, Australasia, Europe, Middle East, South Pacific, UK and USA.
