Rubber suspension parts or PU suspension parts? Which should you use?
Both Rubber and PU parts have their pros, and both have their cons.
In car suspension parts world, the majority of decisions comes down to these two materials and the inevitable question: which one is better for your car?
We will try to explain the pros and cons of both materials below Read more...
All mount sizes (inner sleeve I.D. etc.) match the original ones.
If not specified, the default polyurethane hardness is 65 (Shore A) that is equivalent to original rubber material. This provides safe and comfort driving, meantime increasing the responsiveness of your car. The parts are made separately from arms and steering racks, while genuine parts are often combined with the unit, resulting in customers' overpaying when replacing. The parts are made of PU that is a widely used material to manufacture parts that are capable to withstand heavy-duty conditions. Read more
This is a simple operation for those, who have the hydraulic press, the hubs tooling and the skills of such work. Tampering with the tool due to a lack of skills, or lack of the necessary tools are associated with the risk of damaging the housing bore in the arm or thrust, as well as damaging the new part.
Before beginning the work, pay attention to the location of replacing part in the housing bore. Placement of the Bushing, depth of pressing and other features are important for proper operation of the suspension. Mark the arm and the old part to indicate the correct placement of the bushing. Before installing a new part, mark it the same way as old one. Read more
