HRB RB In Car Valve Spring Tool

Built from firsthand experience in high-performance engine building, the HRB RB In-Car Valve Spring Compressor Tool delivers a smart, workshop-proven solution for servicing valve springs without removing the cylinder head. Designed specifically for twin-cam Nissan RB engines, this tool turns a notoriously frustrating job into a faster, safer, and far more controlled process.

RB hydraulic lifter heads present unique challenges, with valve retainers sitting deep within the lifter bore. To address this, the HRB tool features a specially engineered retainer viewing cup with an enlarged cutaway, improving visibility and access during spring assembly. While precision is still required, this thoughtful design significantly improves ease of use and reduces risk.

• Bronze bushed body for ultra-smooth, controlled compression
• 7/8-inch drive threaded rod for precise manual or powered operation
