Fullsize truck owners love to hate the 8.8", and are often hung-up on the 9", but the 2011 Local Motors' Rally Fighter micro-production 2WD vehicle uses a stock 8.8" with stock TracLok spinning ~33" tires, and is powered by the 430hp/450lb-ft GM E-rod & 4L85E. See the article in Off Road March 2011 p.28-30. In a different article in the same issue, one of the writers expresses a desire to swap an 8.8" into his Jeep, on p.63.
