I know this subject is talked about to death and I have researched heavily, but I was hoping to find someone with real experience re gearing the t100.

I am currently at the stock gearing of 4.10, 5vz-fe, R150F manual. And Goodyear wrangler duratrac LT265/75R16 (load C) on stock 16" steels. Truck has 285,000 miles and runs excellent, Ive owned for 2 years bought for dirt cheap with a broken ifs diff, and put 30k on it since purchasing.

Driveability is quite good around town, on a flat takeoff with a warm engine i can keep the RPM's under 1000 before fully releasing the clutch. Carrying a fully loaded bed on reasonably flat ground is no problem, ive had probably 1300+ lbs in that bed with no issues other than rear springs sagging. However when I leave work (downtown seattle) going up steep (read STEEP) hills, with cold fluids it bogs quite a bit before the engine gets into the power band in 1st. I dislike slipping the clutch that much to get going, and his is with only about 300lbs in the bed.

My question is do I stick with the stock gearing or spend a bit of cash to put 4.56's in? Ill be picking up a 4.30 rear center section tomorrow for $100 that I would like to throw a locker in, but im unsure if I want to undergo the expense of regearing both axles.

Your thoughts appreciated.
