3. Set preload for rear shock to lowest setting.
4. Loosen clamp bolt for the lower shock bolt.
5. Remove all shock bolts and remove the shock.

Kodlin Lowering-Kit assembly and shock installation:
NOTE: All stock bolts must be installed with medium strength thread locker such as blue Loctite®
1. Decompress shock spring and remove shock from the tool.
2. Note the order of parts removal and remove spring from the shock.
3. Replace the stock upper spring seat with the Kodlin spring seat (A).
4. Reinstall shock spring and preload parts paying attention to shock bolt hole orientation.
5. Compress the shock spring again applying pressure to the preload adjuster.
6. Install Kodlin Lowering Kit onto damper (B).
WARNING: Keep fingers away from pinch points when releasing spring compression. Carefully
release compression on the shock spring making sure spring and components are properly seated
in place and centered. If not, compress spring until you can realign parts, then release compression
again.
7. Add grease to the stock shock bearing bushing and O-Rings of the Kodlin mount and install
bushing into the Kodlin shock mount.
8. Reinstall the shock. Torque of upper shock bolt 80-90 ft/lbs.( 108-122Nm), lower shock bolt
70-75f t-lbs.( 95-100Nm).
9. Tighten the clamp bolt of the lower shock bolt 12-15 ft/lbs.(16-20Nm).
10. Install upper frame crossmember and seat.
11. Adjust the shock preload. Check “Owner’s Manual” for details.
12. Recheck that all hardware is securely tightened prior to going on a test ride.
13. These three parts are all that’s removed and replaced.
NOTE: No warranty coverage is provided by Kodlin that is due to improper installation or lack of

Which type of M8 shock do I have and what is correct lowering kit part
number?
Shock “A” above has a mounted pre-load adjuster on the shock itself. You need a HD shock tool or
shock spanner wrench to rotate silver ring. It has numbered square holes to indicate adjustment level.
This shock uses Kodlin part number K66025.
Shock “B” above has a remotely mounted pre-load adjuster. This has the adjuster knob you turn by
hand and sticks out of right side cover. It has numbered lines to indicate adjustment level. This shock
will use Kodlin part number K66024.
Shock “C” above also has a remotely mounted pre-load adjuster. This adjuster is mounted under the
seat and mounts to frame cross member above the shock. It takes a HD tool or 5/16” socket to adjust
shaft on left end of the cyclinder. It has lines along the shaft to indicate adjustment level. This shock
also uses Kodlin part number K66024.
Your factory service manual or user manual should explain how to adjust pre-load for your weight.

Installation Instructions
Step by step pictures using Kodlin Spring Compression Tool #K66030 while
installing Kodlin Lowering Kit manual pre-load adjuster #K66025
1. This is the top plate used for installing #K66025. It has the small notch in center diameter. Your tool
should be assembled as shown in picture on right. Lightly oil or grease the top 2-3 inches of threads
where top plate will be installed. Seen as dark ends of threaded rods in picture.
2. Insert the rod into lower shock end and place shock into the tool, setting rod into the two notches
on plate bottom. Now install top plate, aligning gap with the notch on the shock end. Note the
orientation with the eye on the botton!
3. Install washer and nuts to top plate and snug against shock pre-load adjuster as seen in the picture.
Tip: install setup in vise as seen in picture to hold steady while working.
4. Carefully tighten nuts evenly 1-2 turns maximum at a time until the locknut is exposed.
5.
6. You can use a deep socket with extention to hold shock end while loosening locknut. You can also
put shock end in vise and loosen locknut. Whatever works for you! Remove shock end from the
shock rod. If theshock rod turns you can run the locknut to end of threads on the rod and hold while
unscrewing the shock end. Note: Shock pictured is external pre-load adjuster style.
7. This is what you will remove from left to right to get to the upper spring seat.
8. Remove the top plate from the tool and remove the spring to get to the upper spring seat. The
spring seat on left is replaced with the Kodlin part on the right which is included in the kit.
9. The seat simply pulls up and off. The Kodlin part slides down and seats against the spring clip on
bottom.
10. Reinstall the spring and lower spring seat. Install the pre-load adjuster parts in opposite order you
took them off. Set ajdjustment to lowest (shortest) setting for now. Use the same orientation for the
notch you noted earlier.
11. Now install top plate and make sure plate is centered around top of the adjuster evenly. Align notch
with eyelet on shock end at bottom of picture and gap in cup lines up with notch in plate. Now evely
tighten the nuts 1-2 turns a time until you can install the Kodlin Shock end all the way down onto
the threads of the shock rod.
12. Remember to use threadlocker. Tighten the locknut and then align tab with notch. You are now
ready to release compression of the spring. Keep the tab and notch in alignment as the spring
decompresses making sure the tab falls into place into the notch and the tool’s top plate can move
freely past and is not binding on pre-load adjuster cup.
WARNING! Keep fingers away from pinch points in case something is not correctly aligned.
Compress spring again enough to align parts. If parts move when under pressure and finger is in
the way, you will get hurt so be extremely careful!
13. Now continue to loosen until top plate is loose and spring is no longer compressed. Before removing
top plate visually make sure everything is seated properly and ready for tool to come off. These
three parts are all that’s removed and replaced.
14. Push out the shock bushing from the stock shock end. Kodlin part without the bushing.
15. After lubing the bearing, the bushing slides right in. Bushing installed and shock is ready to go back
onto the bike.
16. Once shock is installed back onto the bike the pre-load can be adjusted as needed.
