Old Air Products introduces the Pro5TEN compressor, a modern, direct-fit replacement for 1959 through early 1961 GM vehicles originally equipped with a GM A5 compressor and a Hot Gas Bypass Valve mounted on the compressor. Designed for a factory look with modern performance, the Pro5TEN bolts directly into the original A5 brackets and uses factory hoses-no modifications required. This makes it an easy upgrade for restorations or maintenance on classic GM vehicles while preserving authenticity. Weighing in at half the weight of the original A5, the Pro5TEN delivers smoother, quieter operation and greater efficiency thanks to its increased piston count. The improved internal design reduces vibration and boosts cooling performance, all while maintaining the correct appearance for your vintage engine bay. The A5 to Pro5TEN Compressor Conversion kits are available in two variations: #21-2259: Designed for the 1959 Cadillacs with a Cadillac specific fitting included. #21-2260: Designed for 1960 GM models and uses all the original hoses and brackets. With its blend of classic fitment and advanced engineering, the Pro5TEN is the ideal choice for enthusiasts looking to keep their classic GM cool without sacrificing originality.
