Need assistance on these two gears for a stock 2wd ranger.
My 97 3.0 5spd ranger is 345 gears and single wheel peel with a 7.5 axle. For what it is now the 345 gears makes it scoot really good, yet I've read 373 gears will improve it all around. Will it really assist with fuel mileage, acceleration, clumbing hills, etc? As mentioned the 345 does good will everything, yet im looking for more improvement. I'm looking to add a limited slip unit to there for traction from both tires. This ranger will stay stock, not building it as I did my 94 3.0 5spd ranger.
My 94 3.0 5spd had 31s with 410 gears with an auburn limited slip unit. Had those installed in 1999, and both were still in there when that truck was taken away from my hands last year. The truck had 90,000 miles when those were installed and it had 653,370 miles last summer..always used motorcraft 80w-90 with motorcraft friction modifier in the axle. Those units had roughly 500,000 and some miles on them and were still going strong.
Is there a major difference between 345 and 373 gears? If so what brand gears are good these days? For limited slip, I'm considering auburn again or what else is good for a limited slip unit?
Any and all assistance is appreciated.
