Description
Overview
The Skunk2 High Lift Valve Springs and Titanium Retainers Set is a performance-oriented valvetrain upgrade designed for the Toyota GR Supra (A90) 3.0 B58 platform and other B58-powered vehicles (BMW models). This kit is engineered to support higher cam lift and improved valve control in performance applications where the stock valve springs may not be sufficient long-term.
Upgrading to these Skunk2 springs and titanium retainers helps reduce valvetrain float, supports higher cam lift, and improves reliability under demanding conditions — making it a strong choice for track-oriented or heavily modified Supra engines.
Key Features
-
Performance-Grade Valve Springs: Constructed from super-clean, high tensile-strength chrome-silicone wire that is shot peened and heat treated for enhanced durability and consistent long-term performance under elevated loads.
-
Titanium Retainers: Lightweight, high-strength titanium retainers reduce valvetrain mass to help maintain stability at higher RPM and with higher cam lift.
-
Improved Valve Control: Designed to offer better valve control and allow additional camshaft lift beyond what is possible with stock springs, making them ideal when paired with high-lift cams.
-
Recommended for High-Lift Cams: While some high-lift camshafts may physically work with OEM springs, Skunk2 specifically recommends this upgraded set when using performance camshafts for long-term reliability.
Specifications & Notes
- Enhanced Performance Use: Ideal for performance builds involving increased cam lift, aggressive tuning, and higher RPM operation where OEM springs can be a limiting factor.
