The 1200 Series builds on this by employing advanced heat-treating operations. These heat treatments increase the strength of the base materials. This increase in strength results in improvement to the fatigue limit of the wire and better resistance to load loss. These factors together allow the engine builder to push the valve train set-up to the next level.\n\nMax Life Surface Preparation (ML)\n\nA proprietary, multi-step surface enhancement process that has been proven to increase spring endurance, Max Life processing is available for any level of PSI spring and is very beneficial for those looking for increased endurance while maintaining their existing set-up.\n\nPERFORMANCE SPRINGS INCORPORATED (PSI)\n\nCo-founders, Bown and Luchi, started PSI in 1996 with the goal of making the best valve springs available for the racing industry.

These were the first PSI valve springs used in a NASCAR race, but they wouldn’t be the last. Within a few years, virtually all of the teams were using PSI?springs, revolutionizing engine building…as well as the country’s most popular motorsport.\n\nABOUT PSI SPRINGS\n\nEach and every PSI spring begins with wire that is made from a variety of high quality Chrome-Silicon alloys. The catalog springs offered by PSI are made from commercially available alloys that use the latest developments in melt technology, composition control and casting practices, and these alloys are held to the strict cleanliness standards. As a result, the use of these super clean materials assures the lowest inclusion content commercially possible. For their custom spring applications, PSI offers the choice of a custom alloy that further improves on properties and cleanliness of the wire through the use of multiple vacuum arc remelting operations. Their superior technology does not stop with the wire. PSI uses state-of- the-art CNC equipment throughout the manufacturing process to ensure batch-to- batch consistency and valve springs that are held to the tightest tolerances in the industry. At PSI, all production processes are done in-house according to strict Quality Control procedures. All PSI springs are 100% load tested and set matched for the ultimate in customer convenience and satisfaction. Currently offering springs for circle track, drag and road racing, PSI springs also feature heat-treating, nitriding and the new Max Life surface preparation process for various applications.\n\nAt PSI, all production processes are done in-house according to strict Quality Control procedures, MADE IN USA\n\nThrough the use of the latest developments in melt technology, composition control and casting practices, our Chrome-Silicon alloys are held to the strictest cleanliness standards ever offered.\n\nAn industry leader since it was established in 1996, Performance Sprints has worked continuously to expand their range of specialized valve spring applications.","brand":"PSI Valve Springs","offers":[{"title":"Default Title","offer_id":52644984029495,"sku":"PSI-DR1250RML","price":1271.95,"currency_code":"AUD","in_stock":true}]},{"product_id":"psi-ct33-01ml-valve-springs-dual-1-29-95-305","title":"PSI CT33.01ML Valve Springs Dual 1.29\" 95\/305","description":"PSI Valve Springs - Dual Springs - CT 33.01 ML\n\nSPRING O.D. 1.290\"\nOUTER ID 0.966\"\nINNER ID 0.716\"\nSEAT PRESSURE 95 lbs @ 1.145\"\nOPEN PRESSURE 305 lbs @ 0.715\"\nRATE lbs\/in. 488.0\"\nMAX LIFT 0.430\"\nCOIL BIND 0.690\"\n \n\n1500 Series\n\nThis series has all the benefits of the 1200’s plus an additional nitriding operation.
