Mark Williams 9″- 9.5″ – With dimensions and offsets very similar to the 9″ Ford, very little modifications are necessary to change over to the 11″. The downside to the 11″ is that it weighs about 75 Lbs. more than a comparable 9″ Ford. Gear changes can be rather difficult also, It is recommended that the 11″ be run in situations where gear changes are not frequent. The cost of replacing worn gears and the dependability of the 11″ make up for its downsides. |
