We partnered with our friends at Small Batch Parts in Australia to get their killer cast inner primary stateside—because good parts shouldn't be a world away.

This cast aluminum inner primary is ready to rip. Built to solve the headaches of the old aftermarket tin inners, this unit is stronger, cleaner, and way easier to wrench on.

Designed for all Big Twin Cone engines 1970–1999 running ratchet top and rotory top 4-speed transmissions. Full rundown below.
