What is the main benefit of a beehive valve spring design?

The beehive shape allows the spring to be smaller at the retainer end and larger at the cylinder head end. This design reduces the overall mass of the spring and retainer assembly, which helps improve valve control and stability at higher engine speeds.

Are these springs suitable for aggressive camshafts?

This kit is designed to work well with stock or mild camshafts. For more aggressive camshaft profiles, it's always best to consult with Supertech or a performance engine builder to ensure optimal compatibility and valvetrain stability.

What does 'loss motion' mean in the context of these springs?

Loss motion refers to a design characteristic that allows for a slight delay or controlled movement in the valve train. This can help prevent valve float and improve the overall stability of the valvetrain, especially during rapid open-close cycles at high RPM.

Product Details

The beehive shape of these Supertech valve springs, along with their loss motion design, helps reduce the mass of the valvetrain. This is a notable change from traditional dual spring setups, allowing for better valve control and stability when your engine is spinning at higher RPMs. They are specifically made for Honda B16 and B18C engines, where managing the valvetrain's inertia is key to performance.

These springs are constructed from high-tensile wire, which is a strong material that can handle the repeated stress of opening and closing valves. The beehive design means the spring is smaller at the retainer end and larger at the cylinder head end, which helps it fit into smaller spaces and reduces overall weight. This reduction in mass is important because it means less force is needed to accelerate the spring, leading to improved performance and reliability in the upper RPM range.

If you're rebuilding the top end of your Honda B16 or B18C and looking to push the RPMs, this kit is a solid option. It's designed to work with stock or mild camshafts, helping to prevent valve float when you're really getting on the throttle.
