I agree, the 7.25 is anemic at best. The jeep 8.25 with disc brakes is much cheaper and stronger that modding the 7.25. I bought a 2000 up Exploder 8.8 with 3.73 posi & discs for $200 complete disc to disc. It pretty much just drops in. Im not crazy about the 3.73s with a 3 speed auto for the street. The 8.8 comes with lower ratios, this one just happened to be near by, complete, cheap and drops right in. Youll need to mod the driveshaft if you upgrade, but its still a lot less than doing discs on the 7.25.
