Ferrea Toyota B58 3.0L 22.53mm OD 15.52mm ID Single Valve Springs - Set of 24

These single valve springs from Ferrea are made with a high-tensile strength spring wire, a material chosen for its ability to withstand the high stresses and temperatures found in performance engine builds. Each spring measures 22.53mm in outer diameter and 15.52mm in inner diameter, designed specifically to work with the valve train components in Toyota B58 3.0L engines. This set includes 24 springs, enough for a complete engine rebuild or upgrade.

Ferrea is known for producing well-built valvetrain components, and these springs are no exception. The spring wire is heat-treated and stress-relieved to ensure consistent performance and durability under demanding conditions. This process helps prevent fatigue and maintains the spring's intended tension over time, which is crucial for proper valve control at higher RPMs. Installing these springs is a key step when you're looking to achieve more aggressive camshaft profiles or increase boost pressure, as they offer improved control over valve float.

When undertaking a project involving the B58 engine, ensuring your valvetrain can keep up is paramount. These Ferrea springs are a solid option for enthusiasts looking for reliable performance. It's important to note that when upgrading valve springs, you'll typically be working on the cylinder head, and it's a good time to inspect and potentially replace other related components like valve seals and retainers to ensure a complete and effective rebuild.
