Q: What are the rebound adjustable "A" & "AC" Shocks?

A: The introduction of Pro Shocks adjustable shocks, is by far a truly unique shock, that is so user friendly that even the entry level racer can use effectively. The shock is totally adjustable on rebound or extension only, not affecting the compression control at all. The Pro adjustable is available in 5, 6, 7, 8, and 9-inch stroke lengths in large body shocks only.

You pick the compresion damping number shock and simply turn the rebound adjuster to the desired rebound number (3-4-5-6-7-8). This shock can be adjusted infinitely from 3 to 8.

No gimmick, this patented rebound adjustable shock has the same sophisticated acceleration ramps and blow-off curves as the standard Pro-Shocks.

All PRO Rebound Adjustable Shock and the PRO Double Adjustable Shock are available in a new high rebound adjustment range. Both of these adjustables are available in an adjustment range from 6 rebound to a very stiff 11 rebound. This patented valving system is infinitely adjustable. As you turn the adjustment, you can stop at any desired partial adjustment, such as 8-1/2, 9-3/4, 10, 10-1/4 or any desired partial number of valving. This new valving system maintains the ULTIMATE PRO shock acceleration curves. Of course the standard 3 valve through 8 valve is still available.
The Rebound Adjustable is available in a desired compression valve such as a 5. Part numbers with a 5 valve would be AC753-8B, & AC756-11B. The double adjustable Shocks would be AC73-7/3-8B & AC73-7/6-11B.

Q: How do I adjust the rebound adjustable "A" & "AC" Shocks?

A: Here are a few tips on adjusting the Pro adjustable.

First you pick the compression dampening number shock you intend to use. You can find this number by holding the housing part of the shock down with the shaft facing upward. There is a number stamped on the top of the shock housing where the shaft enters the shock body. Beside the compression number you will notice a 3/16 allen head female adjusting screw with numbers running clockwise from 3 all the way around (360 degrees) to 8 .

Insert a 3/16 allen wrench into the rebound adjuster screw. You will notice the allen screw has an index pin. This is provided for you to align this pin with the stamped rebound number. Caution should be taken when adjusting the allen screw so that you do not rotate the screw assembly counter clockwise passed the #3 setting. The screw can be backed out against the number plate and damage the shock. The 3/16 allen screw will only rotate clockwise one turn stopping at the #8 setting. Do not adjust passed the #8 setting. This gives you all the rebound choices needed.

Also keep in mind that the allen screw is infinitely adjustable, this meaning you can stop the index pin at any point between the numbers on the plate and you will get controlled change. An example: lets say you are running around the track and your car is loose on corner exit and you want to take rebound out of the right front but the looseness is very minor. You can then make a 1/4 of 1/2 adjustment between the actual stamped numbers on the plate and you will get a minor control change.

Its just that easy!!

Pro Shocks has now given the racer a way to fine tune the suspension without spring changes or bolting on and off shocks with just the aid of a 3/16 allen wrench.
