EJ 5 Stud Conversion Kit (EA81)
Upgrade your Subaru Brumby (EA81) or L-Series (EA82) to modern Subaru EJ running gear! This conversion allows the use of 5-stud wheels, EJ-series brakes and front suspension components — greatly improving braking performance, wheel options and handling capability.
The kit is modular, so you can purchase only the components your build requires.
Note: Although designed for a Subaru Brumby, this kit has successfully been installed onto Subaru L-series. Some information in the instructions may be un-applicable, or alternative steps may be required.
