Single Adjustable Race Inserts

The 8610 series single adjustable strut insert is a twin-tube hydraulic that is externally adjustable in rebound damping. This is an affordable single adjustable option for club racers and autocrossers in North America for vehicles utilizing strut suspensions.

The rebound adjustable is adjustable at the top of the strut rod with a knob that is included. 

The 8610 series is not supplied with a threaded locknut to retain the insert into the strut housing. If new locknuts are required for your application, please refer to the insert gland nut page.

How To Adjust
8610 Series
The 8610 series strut cartridge insert fits a variety of road racing and autocross cars. This insert offers externally adjustable rebound damping with unique valving characteristics that have been developed in conjunction with many top racing teams and chassis builders as a single adjustable alternative to the 8611 series double adjustable insert. The dampers are supplied with an adapter to fit through a 5/8" bearing/camber plate assembly.

To determine the correct 8611 or 8610 insert for your application, follow these steps.
Measure the inside depth and inside diameter of your strut housing.

For the KONI insert to be properly installed, the measure depth of your strut housing must be 1-4mm (.04"-.16") shorter than the dimension "A" in the chart below. Also, the inner diameter of the housing must be larger than the dimension "D."

In the event that the KONI "A" length is shorter than the required, the user must then fabricate a spacer and place it under the KONI insert so as to achieve the proper depth relationship.

After the KONI insert with the correct "A" length has been determined, verify that the stroke length will be appropriate for your application.
