SHOCK DYNO TESTING SERVICE

November 1, 2026 through January 31, 2027

Now that the racing season is over, this is the ideal time to start preparing for next season.  Many of our customers send all their shocks in to be dynoed at this time of the year, so that they can be checked after a long season of racing.  To urge all our customers to check the condition of their shocks before next season, we are reducing the cost for shock dyno service on any A.R.S. shock to $5 per shock until January 31, 2027.  This reduced shock dyno offer will give you a chance to evaluate the condition of your shocks after a season of racing and at the same time review any new valving combinations. When sending your shocks to us for service, please enclose a note with return address, phone number, and a brief description of what you would like done to your shocks or a shock maintenance form is available from our website. After shocks are dynoed, we can call you with the results and discuss the outcome of your shocks or any new shock combinations.  Many customers send all their shocks to us during this special dyno offer, so send your shocks in as early as possible to avoid any delays in preparing for next season.

Valving updates

It is important to stay on top of your shock-valving combinations for your cars. Please call or e-mail us if you have any questions on shock valving. We would be glad to help you review your shock valvings for each corner of your car regardless of what class you are racing. Quarter midget racing is a series of 0.10 of a second you can’t afford to give anything up.

All Four Corners

The 5500 Series shock is designed especially for Quarter Midgets. It has a hard black anodized aluminum body. This shock uses CNC machined aluminum internal parts designed for racing with no aftermarket parts. This shock has a combination of a vase valve design, which allows for very low rod pressure, and a check valve. The gas pressure is already pre-set in the end cap. This shock accepts 1 5/8″ I.D. Sprints.
