Tuning lower shock absorber closure TPS2855

The standard plastic shock absorber closure at the bottom of the models mentioned is equipped with various O-rings and bushes, which often leads to wear and leaks. 

These lower parts consist of 2 aluminum closures, extra long supporting guide bushes of form-retaining POM in combination with oil seals. This means a very flexible damper that no longer leaks and provides much more support than the standard parts.

Fill and Bleed:

• 1)   Remove the oil when necessary
• 2)   Fill the damper up to 10 mm below the rim with new oil
• 3)   Now gently push the rod upwards to just below the oil level
• 4)   Now gently pull the rod back down
• 5)   Now let the damper stand upright for 5-15 minutes so that the air bubbles can come out, (the time depends on the oil thickness)
• 6)   Repeat steps 4 and 5 until there are no more air bubbles in the oil.
• 7)   Now push the rod halfway up the damper
• 8)   Now gently press the red cap without O-ring on so that the excess oil can come out
• 9)   Remove the cap, fit the O-ring and push the cap into the body as far as it will go
• 10) Now screw the cap on.
• 11) The bound and rebound can be set by the amount of oil.

When mounting the lower parts, we recommend that you lubricate the bush and oil seal with a little silicone oil..
