Carmack Engineering’s GEN2 Billet Modular Housing isn’t just another 11-inch rear—it’s the new standard everyone else is chasing. Fully billet, brutally stiff, and engineered with zero compromise, this housing delivers the kind of consistency, strength, and performance that wins championships and sets world records.

We built it lighter than anything in its class—lighter than any other 11″ housing on the market—without giving up a single ounce of rigidity. The GEN2’s modular design maximizes strength where it matters, eliminates flex, and keeps your gear pattern dead-stable under the nastiest power levels you can throw at it.

This is the housing dominating the fastest programs in the world. The one you keep seeing in winner’s circles. The one that’s quietly (and not-so-quietly) kicking everyone’s ass on race day.

If your goal is to run up front, run faster, and stop breaking parts, this is the upgrade that moves you into a different league entirely.
