NEW! Fully Machined Racekit Front Covers

Sonnax 8" and 10" non-lockup racekits are popular with converter rebuilders supplementing their stock rebuilds with performance units for drag, sand rail, rock climbing, swamp buggy and mud racing.

You Asked and We Listened!

In response to many requests to upgrade from partially machined front covers to fully machined covers, we are pleased to announce this exciting development is now being implemented across the entire racekit product line!

  • Fully machined cover with bushing installed
  • Unit-specific design for hassle-free installation
  • Oil flow grooves and holes increase fluid flow to keep converters running cooler
  • Turbine hub features a larger flanged diameter to increase strength and rigidity of the turbine.
  • Clear, detailed instructions

Several newly designed racekits are already available, and more will be released throughout the year as the upgrades are completed. Learn more.
