Manley 11482H-8 Titanium Race Series Valves 2.300" +.250" High Temp

Designed for serious high-performance and competition engine builds, these valves deliver exceptional strength-to-weight advantages over traditional stainless steel valves, reducing reciprocating mass for improved throttle response and higher RPM capability.

Manley's High Temperature (HT) titanium material is engineered to withstand the extreme thermal cycling and combustion pressures found in forced induction, nitrous, and naturally aspirated race engines. The alloy maintains structural integrity at elevated temperatures where conventional titanium grades can begin to soften, making these valves a trusted choice for professional engine builders.

Key Features:

• Head Diameter: 2.300"
• Stem Length: +0.250" over standard (longer stem for custom/performance applications)
• Material: High Temperature (HT) titanium alloy
• Significantly lighter than stainless steel valves — reduces valvetrain stress and improves high-RPM stability
• Superior fatigue resistance for extended race use
• Compatible with standard titanium valve spring retainers and keeper grooves
• Ideal for forced induction, nitrous, and high-compression naturally aspirated builds

Manley Performance has been a leading manufacturer of high-performance engine components for decades, and their titanium valve lineup represents the pinnacle of valvetrain technology for race and track applications. The 11482H-8 is a direct choice for builders seeking maximum performance with proven durability.
