Proven Effective In Years of Hard Use!


Respected TAFC racers Kris & Kevin Hool have relied on an ME 11″ rear end housing for 8 years and not suffered any breakage. Says Kris, “We had 611 runs on our first car and never even chipped a gear. When we built our new car last year we naturally put an MW 11″ rear end in it. So far it’s got 71 runs with no problems. Since it is just my brother and I that run this car, and we don’t have time to keep fixing or setting up new gears, K and K Motorsports will never run anything but MW.”
