Crane Cams current dual valve spring, part Crane Cams 99893, is undoubtedly one of the most popular performance springs sold in the aftermarket today. However, higher performance requirements of ever-aggressive camshaft lobe designs have revealed some deficiencies in what Crane Cams calls “Ole Reliable.” To address these issues, the company has just released a new and improved variant, part Crane Cams 99892. This new design has much in common with Crane Cams 99893, but the slight differences make a significant improvement in performance and useful life! The Crane Cams 99892 is a dual spring without damper. It is also an excellent “total performance,” street performance or moderate racing spring for use with hydraulic roller camshafts or flat tappet cams (hydraulic and mechanical) with tall installed heights. Wire diameter and coil count changes to both the inner and outer springs greatly improve harmonic control throughout the operating range. Super-clean, high-tensile, chrome-silicon valve spring wire assures consistent loads through a long spring life.
