New Dual Valve Spring #99892 complements “Ole Reliable” #99893
This release just sent to Performanceparts.com’s technical department concerning Crane’s new 99892 valve springs. Crane Cams dual valve spring #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 “Ole Reliable“. To address these issues, Crane R&D has just released a new, improved variant as Part # Crane Cams 99892. This new design has much in common with the 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. Specs are as follows:

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. The 99892 is 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! The new spring is priced slightly higher than the 99893, but the improved performance and longer useful life definitely make it a “bargain!” Go to performanceparts.com or contact them for availability and pricing.
