Built from first hand experience in high-performance engine building, the HRB RB In-Car Valve Spring Compressor Tool offers a smart solution for valve spring service without needing to remove the cylinder head. Designed specifically for twin-cam NISSAN RB engines, this tool makes an otherwise frustrating job faster, safer, and more controlled.
Recognising the challenges unique to RB hydraulic lifter heads — where the valve retainers sit deep in the lifter bore — we engineered the retainer viewing cup with a larger cutaway for better access and easier spring assembly. While care is still required, this thoughtful design significantly improves the overall ease of the job.
Compatible with all NISSAN RB twin-cam engine variants and models.
Key Features:
- Billet 6061 aluminium body for lightweight strength
- Billet stainless steel retainer cup with large cutaway for improved access
- Bronze bushed body for ultra-smooth compression
- ¼-inch drivethreaded rod for easy, precise operation
- Captive design prevents tool disassembly during use
- Anodised for durability and corrosion resistance
