Harley Davidson Fork Lowering Kit

Harley Davidson Installation Instruction for Fork Lowering Kit. The installation of a fork lowering kit does not affect the compressed length of the fork. However, we have found that some motorcycles may not have adequate clearance between the fender, fairing and/or accessories.

Therefore, we recommend that this be checked and if there is not adequate clearance, the interfering parts be removed or modified to eliminate the situation. After installation of new top out springs onto the damper rod, we recommend that the forks be installed on the motorcycle complete with wheel/fender, but without the main springs and completely bottomed out. This is done to check clearance between the fender and fairing/crash-bar/accessories, etc

1. Remove and disassemble forks (including removal of damper rod) according to steps outlined in an authorized service manual for your particular model and year Harley Davidson (see figure 1 for reference).
2. To achieve a one inch (1″) lowered height, leave the stock top out spring on the damper rod and install one Progressive Suspension top out spring on the damper rod with the stock top out spring (see figure 2). Proceed to step 4.
3. To achieve a two inch (2″) lowered height, leave the stock top out spring on the damper rod and install two Progressive Suspension top out springs on the damper rod with the stock top out spring (see figure 3).
4. Reinstall damper rods into forks per shop manual. A. Add the proper amount of fork oil as recommended in your shop manual. Make sure the viscosity is the recommended weight. B. Install your Progressive Suspension fork springs with the close wound end up.
