Dirt Winged Sprint Cars

New Products and Valving Updates

A.R.S. now has a new rear shock valving that controls the oscillation of the rear of the chassis. This new valving will take the hop out of the right rear corner. We can make this valving update to any existing gas shocks or any new rear shocks.

We have updated the valving in both the right and left rear shocks. The right rear base valve, piston, and valving curve have been modified. This update was done to handle the rough better without giving up grip. The left rear valve curve has also been updated to improve the chassis through the rough. The left rear shock is one of the most critical on the car. It is important to balance the valving in a shock to have enough rebound to keep the left rear tire driving, but not too much that it kills side bite.

The internal hydraulic bump stop has become a big tuning tool especially on the right rear of a Winged Sprint Car. You can adjust the right rear bump stop to create side bite. This unit is very tuner-friendly compared to a bump stop on the shaft of the shock. It can be fitted to any piggy-back rear shock and has an external adjustment to fine tune the bump stop rate.

 

SHOCK DYNO TESTING SERVICE

Now that the racing season is over, this is the ideal time to start preparing for the 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 of 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. shocks to $10 per shock until January 31, 2024. 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 your return address, phone number, and a brief description of what you would like done to your shocks or a shock maintenance form, which is available on our website. After your 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 the next season.

Left Front

There are a couple of things that need to be addressed in the left front shock dampening. The rebound holds cross weight in the chassis which creates forward bite. Too much rebound pulls the tire off the ground and makes the chassis push mid-corner to exit. The rebound is reduced when the track goes slick to ensure the chassis has good side bite. The rebound dampening requirements change on a short tight corner track versus a fast-sweeping corner track. The compression on the left front is set for corner entry.

 

Right Front

The right front rebound controls the weight transfer to the rear tires. Now with the ability to generate more traction with the rear shocks, we can leave additional rebound in the right front shock. This makes the front end more responsive and, with more control, better through the rough. When the race track dries out, the rebound is reduced for more forward bite. Both front shocks now use the M2 pistons like the rear shocks. This piston allows the front tires to get through the rough and irregularity of the race track.

 

Right Rear

We have invested significant effort in developing a better right rear shock. The right rear shocks have a new valve curve that creates more traction than ever, while still creating enough high-speed control to run the cushion. Balancing both requirements has always been a challenge. By changing the balance of the piston to base valve flow, we have developed a great right rear shock. The rebound range allows you to soften the rebound enough for heavy track conditions and then stiffen it for maximum traction. We lock in the compression dampening and adjust the gas pressure for heavy to dry/slick tracks. This shock is also available in a double-adjustable model, allowing you to adjust the rebound and compression if desired.  We recommend the piggy-back canister on both rear shocks, as it provides more gas volume which makes the right rear tire get through the rough much better than before.

Left Rear

The left rear shock is one of the most critical on the race car. When valving a shock, you need to balance between ensuring it has enough rebound to keep the left rear tire driving and avoiding adding too rebound much that kills the side bite. This shock also contains the new valve curve that creates more traction than ever due to that special valving curve. We build this shock with a 5-degree adjustment needle to be able to fine-tune the low-speed rebound. This maintains more left rear drive in the chassis while providing enough adjustment range for all track conditions. This allows you to back the rebound out and free the chassis up when the track is fast and heavy, and then increase the rebound when the track dries out to create more forward bite. We recommend the piggy-back canister on the left rear also to provide more gas volume to create more traction. This shock is also available in a double-adjustable model to adjust rebound and compression.

All Four Corners – 3200 Series SB Mono Tube A or B Model Double Adjustable with Knobs (Piggy-Back)

All Four Corners

The 3200 Series shock is a small body mono-tube (gas) shock with a hard black anodized aluminum body and canister. This shock uses CNC machined aluminum internal parts designed for racing with no aftermarket parts. These shocks contain the latest T/C valving for maximum traction. This shock comes in A or B-Model Double Adjustable with Knobs. The base valve design in this shock allows for very low gas pressure to be used and still function properly. When combined with our canister option and the ability to run low rod pressure this shock has virtually no rod pressure build up and allows for maximum grip a driver can feel.  This shock allows the racer to adjust the rebound and compression dampening completely independently. This shock allows for the rebound to be adjusted at the eye of the shock and the compression to be adjusted on the remote canister of the shock.  This shock has a Schrader valve that will accept 10-100lbs. gas pressure which provides for fine tuning of the chassis balance. The small body shock accepts 1 7/8”, 2 ¼” & 2 ½” I.D. Spring & is available in 5”, 6”, 7”, 8” & 9” shaft lengths.

(Piggy-Back Style is the mount connecting the canister to the shock, opposed to the canister being mounted to the chassis itself.).
