4000
The ultimate double adjustable mono-tube shock allows the racer to adjust the compression and the rebound dampening completely independently with no bleed-over shock dampening.
The rebound dampening can be adjusted from the eye of the shaft with a 9 position adjuster (E model) that has a detent stop in every position. These shocks are also available in a cockpit adjustable shock. (A or B model).
The 6 position compression adjuster is located in the remote reservoir with the schrader valve for fine tuning the gas pressure in the shock.
The unique piston design in this shock allows you to create various valving curves from liner to digressive and many options in between.
The 4000 Series Double Adjustable Shock is machined with a thread design to provide ¼” of spring adjustment for every one turn of the coil-over nut.
The shock body will accept 2¼” or 2½” I.D. springs and is available in 4”, 5”, 6”, 7”, 8” and 9” shock shafts.
The 4000 Series Double Adjustable dramatically reduces your shock inventory. In most cases you need only one shock per corner of the race car to cover all your dampening needs.4000 E-Model
The new black hard anodized billet aluminum bodies contain the finest machine work in the shock industry. The redesigned compression reservoirs have more dampening range change than any double adjustable shock on the market.
Maximum traction is developed with the use of the lowest rod pressure in a monotube designed shock.
ARS prints a detailed dyno sheet with each shock showing all the adjustment ranges of the rebound and compression dampening values of each shock. An easy conversion chart is also available to convert dyno numbers to standard part numbers for each shock.
The double adjustable shocks are owner rebuildable or if you don’t have the time or the access to a shock dyno, ARS will be glad to be your “Shock Guy” for you in the future.4000 Non-Adjustable
The 4000 series non-adjustable shock is designed for asphalt late model series where adjustable shocks and base valves are not legal. This shock has many of the advantages of the 4200 series shock but requires more gas pressure during operation.
Being a non-adjustable, we have made this shock very easy to revalve and rebuild. We have created detailed revalve instructions for customers wanting to revalve their own 4000 series shocks.
The black hard anodized aluminum bodies contain the finest machine work in the shock industry. The one piece closure nut contains a very low drag seal to reduce seal drag to a minimum and insure constant low speed dampening control.
The shock body will accept 2 ¼” or 2 ½” ID springs and is available in 5”, 6”, 7”, 8”, and 9” stroke shafts.
