COMP Cams 790-1 Titanium Valve Spring Retainer 1.450 in. Special for HDSE

The COMP Cams 790-1 is a high-performance titanium valve spring retainer designed for special heavy-duty single spring (HDSE) applications with a 1.450" outside diameter. Precision machined from aerospace-grade 6AL4V titanium alloy, this retainer delivers an exceptional strength-to-weight ratio that outperforms traditional steel retainers — a critical advantage in high-RPM racing and performance engine builds.

Key Features:

• Machined from 6AL4V titanium alloy — the same material used in aerospace applications — for maximum stiffness and minimal warpage
• Lighter than steel retainers, reducing valvetrain reciprocating mass for improved power and engine response
• Heat-treated and processed to stringent tolerances for superior durability and dimensional consistency
• Features COMP Cams' Super Lock™ retainer design for secure, confidence-inspiring valve lock retention at extreme RPM
• Designed for special heavy-duty single spring (HDSE) applications with 1.450" spring outside diameter
• Sold individually (1 per package)
• Works best when paired with COMP Cams valve locks and optional lash caps

Whether building a high-revving race engine or a demanding street/strip powerplant, the COMP Cams 790-1 titanium retainer provides the reliability and weight savings needed to push performance to its limits. COMP Cams MPN: 790-1.
