In 2wd, they get the exact same mileage.My sister originally had a 242 in her ZJ... and after a fun weekend the chain started slipping badly resulting in the thing grenading... replaced with a spare 231 we had and it drives butch better now
242's get crappier milage as well as not being as strong.... stick with the 231
Yeah but the first guys that are reporting back on their 241 upgrades are saying it's a real biatch of an upgrade, not even close to being a direct bolt in. Worth the effort but it's not an easy job, especially where getting it mounted to the skidplate is concerned.The only reason to throw out the 231 is for a NV241OR out of a Rubicon. Thats a upgrade, the 242 ist a downgrade.
