Interesting Notes
The adjusting cam on the 1965 XLH and Electraglide covered style shocks had to be factory changed to a smaller diameter to eliminate the step at the bottom end to prevent contact with the cam and the cover when the shock telescopes to the compressed position. The old cam had a lipped out area past the end of the cover that was larger in diameter than the cover ID with a step between the two different dims on the cam. 18)
Shock Conversion Kit 54529-76
- Basically, a new stud kit (one for each side) was needed to retro-fit '67-'74 shocks to the new '78 Showa shock assembly including;
- Upper and lower studs, washers and an outer bolt cover.
