Insert the rebound damper piston and seal head into the upper tube.
Push the seal head into the upper tube until the retaining ring groove 
is visible.

Push the rebound damper into the upper tube and thread a bottom bolt 
into the shaft.

Retaining rings have a sharper edged side and a rounder edged side. 
Installing retaining rings with the sharper edged side facing the tool 
will allow for easier installation and removal. 

Install the retaining ring into the upper tube groove. 

NOTICE

Do not scratch the rebound damper shaft. Scratches will allow oil to 
leak into the lower leg, resulting in reduced damping performance.

CAUTION

Confirm the retaining ring is properly seated in the retaining ring 
groove by using the retaining ring pliers to rotate the retaining ring 
and seal head back and forth a few times.
