Features

• Medical-grade titanium construction for extreme valvetrain durability and strength
• Approx. 42% lighter than OEM steel retainers, reducing rotating mass in the valvetrain
• Radius-cut edges and lightening grooves enhance rocker-arm clearance and weight reduction
• Optimised for high-RPM stability - suitable for aggressive camshafts and valvetrain upgrades
• Reduced overall height design improves valve seal clearance and frees up additional lift margin
• Serialized batches for traceability and quality control
• Direct OEM-style fitment for Honda/Acura B-Series and H-Series DOHC VTEC engines
• Ideal companion for aftermarket valve springs or full performance valvetrain builds

Specifications

• Material: Medical-grade titanium alloy
• Approximate weight reduction: 42% vs OEM steel retainers
• Engine platforms covered: B16A, B17A1, B18C1, B18C5 (Honda/Acura B-Series) and H22A1, H22A4 (Honda H-Series) DOHC VTEC
• Requires compatible valve springs and retainers - review camshaft, spring pressure and valve height parameters carefully

Product Description

The Skunk2 308-05-0300 Titanium Valve Retainer Set is engineered to elevate high-RPM performance on Honda/Acura B-Series and H-Series DOHC VTEC engines. By drastically reducing valvetrain mass (approx. 42% lighter than OEM steel retainers), this set enables cleaner valve control, higher rev limits and improved stability under aggressive cam profiles.

Constructed from high-integrity medical-grade titanium and manufactured with advanced CAD/FEA processes, these retainers feature optimized radius cuts, lightening grooves and reduced height design to benefit high-stress performance engines. Direct fit for B16A, B17A1, B18C1, B18C5 GSR/TypeR and H22A1/H22A4 Prelude applications, they're perfect for valvetrain rebuilds, track rigs or serious performance builds.

Installation requires attention to spring pressure, installed height and valve clearance - as typical in VTEC builds. While this set is designed for high-RPM use, your overall valvetrain hardware (springs, keepers, cam, head condition) must match accordingly. Fitment confirmed through 2001; beyond 2001 coverage (e.g., later K-Series engines) is unconfirmed at time of listing.
