Katech LS/LT Extreme Duty H13 Tool Steel Dual Valve Spring Replacement Retainer

Individual Hardened H13 Tool Steel Retainer for Compatible PSI Dual Valve Spring Packages.

The Katech LS/LT Extreme Duty H13 Tool Steel Dual Valve Spring Replacement Retainer is engineered and manufactured by Katech Engineering in Clinton Township, Michigan, USA. Designed for PSI-LS1512 and PSI-LS1513 dual valve springs in compatible LS, LT1, and L83 valvetrain packages, its hardened H13 tool steel construction provides increased long-term wear resistance compared with titanium retainers in evaluated Katech camshaft packages.

Sold Individually. Each purchase includes one Katech LS/LT Extreme Duty H13 Tool Steel Dual Valve Spring Replacement Retainer.

Katech developed this retainer on its Spintron valvetrain dynamics test cell for demanding racing conditions. Steel valve springs can wear into titanium retainer contact surfaces over time; this H13 tool steel design provides an alternative where spring-contact wear and service life are important considerations.
