shocking facts

Asphalt late models are now using softer front springs, stiffer rear springs, the use of bump rubbers and the technique of coil binding springs. Selecting the proper shocks and valving curves is more critical than ever before. Utilizing soft springs in the front of the chassis requires more low speed rebound than old conventional setups. Without increased low speed rebound when the chassis drops down on corner entry the chassis will pop-up unloading the front suspension. Increasing the amount of front rebound dampening is important in keeping the front nose valance down and flat through the corner to generate maximum downforce from the body of the race car. Too much rebound dampening in the front shocks does not allow the front tires to follow the race track across the bumps or irregularities of the race track. ARS has created valving curves that generates the maximum amount of very low speed rebound for weight transfer control while creating a very digressive high speed dampening so the tire is able to follow a bump. Creating multiple adjustable rebound needles with different angles to fine tune the low speed rebound dampening has become a great tool in creating the proper rebound ranges. The 5 degree needle in the LF shock has become critical in fine tuning the correct amount of rebound dampening. The 10 degree and the 5 degree needle in the RF shock allows you to fine tune the rebound control. The 5 degree needle is used on race tracks that are smooth or have a lot of grip. The 10 degree is used on short tracks that require changing the dampening between qualifying and the race. Using increased rebound dampening in front shocks limits weight transfer to the rear of the chassis. This requires increased mechanical grip to be generated by the rear shocks. This is achieved by increasing the low speed rebound dampening in the rear shocks to create forward bite. Drivers are amazed with the amount of traction these rear shocks can generate.

Reasons Why Shocks built by Are the Best in the Industry


Everyday the people at Advanced Racing Suspensions are working on new and better valving combinations. Experience from extensive race track testing is translated back to the shock dyno to develop the best shock valving possible.
