Skunk2 Toyota Supra MK5 / BMW B58/S58 High Lift Valve Spring & Titanium Retainer Set

This is the Skunk2 Racing High Lift Valve Spring and Titanium Retainer Set, specifically made for the Toyota Supra MK5 and BMW models equipped with the B58 or S58 engines. If you're looking to push your engine's performance further, especially in applications where higher RPMs or more aggressive camshaft profiles are involved, this set is a critical component for maintaining valve control and reliability at those elevated levels. It's designed to handle the increased demands placed on the valvetrain when you're modifying your engine for more power.

What sets this kit apart is the combination of high-lift springs and lightweight titanium retainers. The springs are engineered with a higher spring rate than stock, which is essential for keeping the valves securely closed at higher engine speeds and under increased boost pressure. This prevents valve float, a condition where the valves don't close fast enough, leading to lost power and potential engine damage. The titanium retainers are a significant upgrade because titanium is much lighter than the steel used in stock retainers. This reduction in mass at the top of the valvetrain means less inertia, allowing the springs to work more efficiently and the valvetrain to operate more smoothly and accurately, even at very high RPMs. This is a well-built set that addresses the needs of serious engine builds.

When undertaking a valvetrain upgrade like this, it's important to have a solid plan. This set is designed to work with specific camshafts and requires careful installation by a qualified technician. Ensure you have all the necessary supporting components and tools before starting the job. This kit is a key piece for anyone serious about maximizing the performance and durability of their Supra MK5 or BMW B58/S58 engine.
