I currently have 3.55's and I'm running 285/75/16's. I tow about 4 times a year and the rest is daily driving. My question is, should I do a ring and pinion swap? If so, what ratio?

 

Which engine?

 

oh, sorry... 4.6L

 

Well since you also have a thread concrening a lift. I was originally going to suggest 4.10 gears but 4.56 would probably be better especially if you are 4x4

 

What kind of driving, -city or highway ? What do you run the most ?

 

Have a 2wd.... Unfortunately....


I drive mostly on the highway 24 miles round trip.

 

Maybe go with 4.30 gears for in between should be able to run any tire up to a 35's, but J-brew has more knowledge than me so I would go with his advice. Wish I could get 4.30's for my truck

 

See what your RPM's are at cruising speeds, -EMPTY, not hauling anything and in OD. Around 1900 is a good max. More than that and it's going suck quite a bit more fuel.

Yea, I agree, -at least 4:10's w/33's IMO.

 

Thanks for the compliment, but I'm not running that set up, never have actually. Yea, maybe something in between 4:10's and 4:56's. I would try to keep it around 1900 rpm's tho, if it was my dd. So the mileage won't get to ridicules lol.

 

4.10s with 31-33's would be a good combo if you tow. However if you plan to go to bigger tires like 35s I'd recommend 4.56's.

 

i wouldnt regear

 

If you're lifting and putting 35's on it I would get 4:56 gears. 4:56 will def help that the 4.6L get those tires moving. If using 33 inch get the 4:30's. I had 35's on my old truck with the 5.4 and 4:56 gears and loved it!

 

At 60mph I'm at 1500 rpm. How's that sound?

 

If that's your normal cruising rpms, - yea , plenty of room for taller gears. With 3:55's I'm @ 1900 rpms on cruise. But I cruise @ 78-79 mph.

 

Yea well, - that's because the 4six would be at the curb with a SC 5four taking it's place... I know.
