Upgrade Your Valve Train Without Cutting Corners

If you're building power into your Duramax and want peace of mind at high RPM, Comp Cams 701-32 Steel Retainers are a smart investment. These retainers are built to handle the added stress of performance valve springs, especially when you're running aggressive tunes or heavy towing setups. They’re precision-engineered for the 2011-2016 GM Silverado and Sierra 2500HD/3500HD models with the 6.6L Duramax LML, so you get a perfect fit right out of the box. Each set includes 32 retainers and is specifically designed to work with COMP’s Beehive™ valve springs, part numbers 26113 and 26125. The black oxide finish doesn’t just look good, it also holds up against corrosion in high-heat, high-stress environments. Whether you’re building a daily-driven tow rig or a weekend track truck, these retainers offer the kind of durability you don’t have to second guess. When reliability and performance both matter, Comp Cams delivers with proven components you can trust.

Engineered Strength That Handles The Hard Stuff

Comp Cams didn’t just tweak an old design, they completely re-engineered their retainers using advanced 3D CAD modeling and finite element analysis to reduce stress, trim unnecessary weight, and allow for increased valve lift. The 701-32 retainers are CNC-machined to exacting tolerances using high-grade SAE 4140 chrome moly steel, a material known for its strength, consistency, and resistance to fatigue. They're made to accommodate valve springs with diameters ranging from .959 inches to 1.013 inches, and the 7° lock angle ensures a secure hold under extreme pressure. These aren’t generic parts, they’re precision-matched for use with COMP’s Beehive™ springs to maintain proper valvetrain geometry and performance. The lightweight design also helps reduce mass at the top of the valve, which improves engine responsiveness and RPM stability. Every detail, from the contoured top profile to the corrosion-resistant finish, is purpose-built for high-performance applications. This is the kind of upgrade that pays off where it counts, inside the heart of your engine.
