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.

1. Remove fork springs according to instructions contained in your shop manual. For maximum performance we highly recommend that the forks be thoroughly cleaned, inspected and new fork oil installed. Note: If your motorcycle comes equipped with two fork springs in each leg (long & short), remove and discard both springs and the flat washer between the springs. If a stock spacer exits, remove it. If there is a short spring on the damper rod, do not remove it! 2. Use the recommended fork oil viscosity as noted in your owners manual with the following exceptions: GL1100 20 weight, GL1200/1500 15 weight required. See fine tuning for more in- formation. Fork oil level/volume should be checked according to the steps outlined in your authorized shop manual. Measurement of your fork oil by level is the preferred method. However, some manuals only specify a volume measurement. Due to the design of a progressive wound fork spring it will displace more oil thus requiring a maximum oil level of 5.5″ (140mm). Caution: This is not a recommendation, it is only a precautionary statement. If your manual specifies an oil level higher than 5.5″ (140mm) set the oil level at 5.5″ (140mm). (Oil level is the distance from the top of the fork tube to the top of the oil with the fork completely collapsed and the fork spring removed see figure 1.) This measurement can be made by using either one of the Progressive Suspension Fork Oil Level Adjusters (FOL-1 or FOL-2). 3. Install your new fork springs into the forks. Mechanically, it makes no difference which way the springs are installed. Some manuals will state; install the spring with the close wound end towards the bottom. This is done because sometimes there will be less spring noise. The springs will perform exactly the same regardless of which direction they are placed. Check the spacer length requirement for your motorcycle in the enclosed supplement. If not listed, you must calculate the pre-load. What is pre-load? Pre-load is the distance the spring compresses when the fork cap is installed. You may or may not utilize a spacer to achieve proper pre-load. The spacer in itself is not “pre-load”. It just helps to achieve it. Why is pre-load important? It determines the proper ride height which in turn affects how the bike handles.

Place the motorcycle on the centerstandor block the motorcycle securely so the rear wheel is slightly off the ground. 2. Remove the old shocks and note location of mount- inghardware. If additional accessories are installed on your motorcycle, please refer to their mounting instructions for removal to gain access to the shocks. Note: Steps (3-5) are only necessary if aftermarket fender, tire or any other accessories have been installed. If none of these applies, 18 Series proceed to step 5,418 Series proceed to step 6. Caution: Make sure that the proper bushings/sleeves are installed in the shocks. Improper bushings/sleeves can cause unsatisfactory or unsafe operation. Bushings: A universal hardware kit is included. Determine the proper sleeves and washers for mounting stud/bolt for your particular application. Not all parts will be used. 3. Install one shock (without spring) and check clearance (#Ain Fig. 1). Raise wheel into fender well until shock bottoms. There should bea minimumof1″of clearance between the tire and fender. 4. If clearance (#A) is sufficient, remove the shock and install the springs onto the shock (See Step 5). Caution: This step requires a spring compression tool from Progressive Suspension, (Part#32-5503). If a spring compression tool is not available, refer the work to your local dealer or repair shop. Attempting to compress the springs without the proper tool may result in serious injury or damage to the shock! 5. Spring Installation: A. Install tab cover and cam adjuster to the minimum setting (lowest point on preloadramps). See A figure 2. B. Install plastic body protector insuring that the protrusion seats into the cam adjuster. See Bfigure2. C. Install the spring. D. Install retaining ring above the spring. Make sure the circlipbevelis facing upward. Place the wirecirclip over the top eye sliding it close to the retaining ring. See Cfigure 2. E. Using a spring compressor tool, compress the spring enough to install wire circlipinthe groove. Slide the wire circlipdowninto the groove. Release the spring slowly, making sure the spring retainer ring seats fully on the wirecirclip. See Dfigure 2.
