The Showa Genuine Shock Piston Rod Complete is a replacement shaft assembly for the Kawasaki KX450 450SR 450X rear shock absorber. Manufactured by Showa to original equipment specifications, it is designed for rebuilding damaged or worn shock absorbers while maintaining original fit, performance and reliability. Available with either a Diamond Like Carbon (DLC) or Rainbow surface coating, it provides a durable, low-friction running surface for the seal head and guide bush.

Why Choose Genuine Showa Parts?

The piston rod is one of the most highly stressed components within a rear shock absorber. Surface finish, straightness and dimensional accuracy all influence seal life, friction and long-term suspension performance. Genuine Showa replacement components are manufactured to the same standards as the original equipment, helping ensure consistent operation and reliable service life following a shock rebuild.

Technical Information

DLC-coated piston rods provide an extremely hard, low-friction surface that helps minimise wear between the shaft, seal head and guide bush. Combined with genuine Showa components throughout the assembly, this helps maintain smooth suspension movement and long-term sealing performance under demanding riding conditions.
