Installation Instructions (English) 700 PK Unbreakable Pump Rings for engines that rev under 5400 RPM Unbreakable High-Performance Pump Rings for engines that rev above 5400 RPM We know the sick feeling in your gut and the pain in the brain when a job comes back with broken rings.пїЅ Most of the time it takes the trans and the converter along with the pump, and the customer is positive itпїЅs all your fault.пїЅThe rings in this kit are not cast iron or compressed metal.пїЅ They are not brittle.пїЅ They are tough, hardened steel. Because they are slightly larger and stiffer, pump efficiency is increased. You will notice higher pressure at hot idle.пїЅпїЅThe kit also includes a priming spring that corrects the high rev drop that occurs above 5500 RPM. You may have noticed that max throttle up-shifts on high revving models gets soft. This kit corrects high rev pressure drop. Features: High carbon, heat treated and annealed steel Precision-ground for thickness and outside diameter Corrects/Prevents/Reduces: Pressure regulator buzz or moan (especially hot) High rev pressure drop Includes: (2) USA-made high carbon, heat treated and annealed steel rings Slide spring
