Super Pro - Polyurethane Bushes
Super Pro is a polyurethane elastomer base material, and is a class of "Thermosetting" synthetic polymer that involves the reaction of various types of isocyanate resin with curing agents, to give an extremely durable material with the best features of rubber and plastic. Super Pro is unique, it is the only polyurethane product range fully backed by a professional research and development program based on many years of hands on experience in the suspension industry.
Super Pro designs incorporate the latest technology in polyurethane as developed by the Super Pro Research and Development Team. Design features such as bullet grooves, knurled and spiral bores and grease grooves ensure that the product performs to the highest standard without transmitting any excess noise, vibration and harshness (NVH).
Super Pro components are produced to the highest achievable tolerances for polyurethane. This is essential for the correct fit of each component resulting in the life of the product being maximised and to ensure that the vehicle componentry is not over stressed and damaged. All the steelwork used in the product range is precision machined for precision fitment.
The crush tube is an integral component of the suspension bush system and is necessary for free pivoting. The crush tubes are made to precision tolerances to ensure that the precise fit is maintained.
Where ever an outer shell or sleeve is used in the Super Pro product range you can be assured that it is also made within precise tolerance ranges.
The double helix is a design feature that has lead to improvements in the Super Pro product. The double helix is used in two applications. The first is on the inside of the bush and the second is on the outside diameter of the crush tube.
The first design of the double helix is used primarily on shackle bushes. The double helix provides 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 is used on control arm bushes to enable unrestricted pivoting of the polyurethane bush around the crush tube. The knurling has two inherent design advantages. The knurling reduces the surface area of polyurethane in contact with the crush tube. This reduction in surface area results in less frictional forces being developed. The Super Pro 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 Super Pro 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 load is applied during normal vehicle operation. 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 harshness and NVH within the bush and its mount.
The tangential grease grooves in the heads of shackle bushes have reduced 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.
Subaru Front and Rear Heavy Duty Alloy Sway bar Links
SuperPro heavy duty alloy links are now available for the Subaru Forester, Impreza and Liberty offering a replacement of the Original Equipment plastic links. This will allow the sway bar action to work more efficiently in transferring the cornering force through to the opposing wheel, for maximum traction, cornering ability and performance.
VR-VE Commodore Strut Top Mount
After stringent testing and design modification, Fulcrum Suspensions has now released the SuperPro Commodore VR-VE top strut mount in Polyurethane, further increasing the range of SuperPro products.
The SPF1590K mount allows more positive location for accurate wheel alignment settings. This is done by reducing the movement at the pivot point that the vehicle forces place on this mount, while maintaining the critical original equipment ride height. This component also makes the shock absorber work more effectively due to less flexing in the top mount, allowing suspension and road feedback to be absorbed by the strut for a quicker response.
There are two kits available with SPF1590K containing the two top mounts and SPF1590BK containing the mounts and replacement bearings.
