These trunnion and bushing conversion kits require only the use of snap ring pliers and assembly lube or oil to assemble, and are made from the same materials that we have been using on our trunnion conversions since February of 2006. They are made from our proprietary bushing and valve guide material that we have been using for over 30 years. The bushings are designed to slip fit onto the trunnion and into the rocker and therefore do not need the use of special tools or a press. This design will increase the amount of usable wear surface, as the bushings will continue to rotate in the rockers and around the trunnion. Our oiling design is the same as it always has been, grooves that are machined in a spiral pattern around the bushing on the OD and ID. The trunnions are heat treated steel and precision ground to hold a +/-.0002” tolerance. The trunnions will accept both OEM and ARP bolts, as they always have, and we recommend a maximum lift of .670”. They were originally designed for Wegner Motorsports for use in the Spec Motor programs, and they have tested them to 9500 RPM without any failures.
We have kits in stock at this time with pricing at $199.95 plus shipping. Please feel free to contact me with any questions or concerns you may have and I will be happy to help.
Thank You!
