Rear Shock Lowering Outer Kit 46 mm KYB/WP – For YZ250F, CR250R, KX250, RM250, 250EXC-F & More (–50 mm)

Quick Installation Without Full Disassembly:
Designed for convenience, this rear shock lowering kit can be installed without disassembling the shock damper* while maintaining the suspension’s original performance.

Adjustable Ride Height:
Allows –30mm to –50mm of rear lowering by pressing and fixing the seal head from the outside of the damper, reducing seat height and improving footing for better control.

Smart Lowering Design:
Shortens the extended length without changing the full bottom-out length, helping prevent tire and fender interference—common in standard lowering setups.

Durable Construction:
Compatible with 46mm cylinder bores (KYB/WP) and 50mm bores (KYB/SHOWA/WP). Made from precision-machined, high-strength aluminum components designed for long-term reliability.

Optional Lowering Combination:
Can be paired with a lowering link for additional seat height reduction.

*Requires oil and gas removal before installation.

Notes:

• For some models, the piston rod stroke becomes slightly shorter due to collar thickness, which also reduces overall shock body length.

• Because the spring seat moves upward by the collar’s thickness, verify available thread adjustment space before assembly.

  • Required thread space: 14mm for –40mm / 17mm for –50mm lowering.

  • If there isn’t enough thread space, a shorter spring will be required.

• Compatible with 46mm cylinder bores (KYB/WP) and 50mm bores (KYB/SHOWA/WP).

• Can be used together with a lowering link for further height reduction.
