I Driver a 300 TDI Disco with an Auto that I bought off Defender Source last year and this Spring I'm going to install lockers. I'm trying to decide if I should re-gear at the same time. I have 245/75's on the truck and do not plan to go bigger. Right now I'm happy with the gearing, but was wondering if I should change from 3.54:1 to 3.9:1 when I add the Lockers. The only time I really fell the lack of power is when the truck is loaded for camping. Can anyone think of any disadvantages to this? or is the jump so small that it wont make a difference.

thanks for any input

My 98 TDI auto runs 265/75/16 mud tyres on standard gearing, i am happy most of the time except when towing my camper trailer thru hilly country.
Unless you plan on running 33's all the time i wouldnt change the gearing, maybe a pump tweak and exhaust mod would help.
