well, Ive gotten the money scooped together for the 36 tsl's, but not quite enough money for gears, well more like no money after tires. I cant put off getting tires for much longer, so im wondering how the gearing will be on my f150, 3.55 gears, mazda 5 speed, and a 300-6. I beleive it was hornythorny i was talking to, and he said his buddy had 37's on 3.55, but would like some more input.

3.55 is pretty crappy for 36's and a 300-6. 4.11's would make a good improvement.

I ran my bronco on 33s with 355 gears and the I6.

Sucked on the highway but was okay on gravel after I put it in low range.

I now run 36 tsls with 411 gears and a t18 tranny(no od)

it's much better but still sucks going up hill on the highway

i had 35's and a 300 I6 with 3.55's. it sucked. hard enough to drive on the street let alone wheel it. spring wrap became an issue

my old bronco ran fine on 36's with the 355's but when wheelin it had to be in low range.
It had awsome mileage on the hwy too

With my 302 and AOD, I've had 33's w/ 3.55's, 33's w/4.56's, 35's w/4.56's, and now run 37's w/5.13's. The 5.13's are best for overall driving and wheeling, but still could go lower for off-road use.

For your I6, I'd consider 4.56's or 4.86's, but either way you will suffer on the highway.

get rid of the Mazda tranny and change your tranny to an np435 or a ZF so that you have a better 1st gear in either and the zf though not as low as the 435 gives you an OD.

4.10 or 4.56 with an I6 works well 3.55 is not a great choice .

i say 4.88:1 if you going to re-gear

no point going through all the hassle to only change one or 2 ratios up.

it should still be good at highway speeds cause you got a 5th gear and a tractor motor:D

yeehawww got to love the tractor motors :D

so, after seeing the replies, i think im going to sit on this money, and save for gears. but damn, im on a new job site which requires driving to vancouver from cloverdale everyday, so im thinking the tsl's are not the best choice money to wear wise. so im looking at getting a nice 35 that wears well. should i still re gear for 35's? ;)

I would regear if you are only driving on the larger tires everyday..

Or go the route I did and mount the large tires on a spare set of rims and run street tires the rest of the time.

Ive been runnung 4.56's for a year now with 35's on my bronco, works great, ive got the ZF-5 though to, so the overdrive is nice on the highway. 100km/h is roughly 18-1900rpm.
