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. Most of the time it takes the trans and the converter along with the pump, and the customer is positive it’s all your fault. The rings in this kit are not cast iron or compressed metal. They are not brittle. They are tough, hardened steel. Because they are slightly larger and stiffer, pump efficiency is increased. You will notice higher pressure at hot idle. The 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
