FAQ

Will Koswork KOS02001 X-rings fit my RC shocks? These X-rings are designed for compatible shock absorbers with 3mm diameter shafts. They measure 1.78mm thick with a 6.4mm outer diameter. Check both the shaft diameter and the shock seal cartridge dimensions before purchasing, as not every 3mm shock uses the same seal size.

Are these X-rings suitable for Team Associated and TLR shocks? Koswork recommends them for compatible Team Associated, TLR, Yokomo, Kyosho and Schumacher shock absorbers. However, fitment depends on the specific shock design rather than the vehicle brand alone.

What is the benefit of an X-ring compared with a standard O-ring? The X-shaped cross-section is designed to provide effective sealing while reducing friction against the moving shock shaft. Results depend on the shock cartridge, shaft condition, lubrication and correct installation.

Does the package include shock seal grease? Yes. The set includes 1ml of special O-ring grease formulated to lubricate the seals without causing the swelling or deformation associated with unsuitable lubricants.

How many shocks can one pack service? The package contains eight X-rings. This is enough for four shocks if each shock uses two X-rings. Check the assembly instructions for the number required by your particular shock absorbers.

Important Notes

• These X-rings are designed for compatible 3mm shock shafts and are not a universal fit for all shock absorbers.
• Confirm the seal cartridge dimensions as well as the shock shaft diameter before installation.
• Clean the shock shaft and seal housing thoroughly before fitting replacement seals.
• Inspect shock shafts for scratches, bending or wear that could damage new X-rings or cause oil leakage.
• Use the included grease according to the shock manufacturer's assembly instructions.
• The number of X-rings required per shock varies by design.
• Shock absorbers, shock oil, vehicles, tools and other accessories are not included.
