The Yokozuna 4mm Shimano/SRAM Shift Housing Kit is a complete DIY solution designed to refresh and improve shifting performance on road and mountain bikes. It is optimized specifically for Shimano and SRAM drivetrains using 4mm shift housing.

Jet-Lube Technology: This kit features Yokozunas Jet Lube process, which injects lubrication through the entire length of the housing rather than only at the ends. Full-length lubrication reduces internal friction and delivers approximately 10% less cable drag for smoother, more precise shifts.

Shifting Performance: The low-friction housing paired with quality inner cables ensures crisp gear changes and consistent lever feel. Reduced drag helps maintain reliable shifting performance even with complex internal cable routing.

Complete DIY Kit: The kit includes shift housing, inner cables and ferrules, making it ideal for full cable replacements or drivetrain upgrades. It is well suited for home mechanics and workshop use alike.

A practical upgrade for riders looking to restore smooth shifting and improve cable efficiency without changing drivetrain components.
