Ive heard bout the "bulldog stance". It's not that bad but it kinda kills visibility. The truck came stock with 2 blocks in the back. Would adding another one do any harm?

 

You already have two blocks in back? (as in, two on each side...) That shouldn't be like that if it's stock.

 

Yep. I think is one 3" lift block and 1 seating block ( 1" inch tall at most). That's on each side. The front is quite stock as far as I can tell.

 

as far as mpgs i run 37's and get about 9.5 mpgs. that also with a slightly numericall higher gear ratio than you at 3.93

 

I'd have to go look at mine... but, I think the stock block is supposed to be like five inches, and there is only one...... Will look tomorrow.

 

So if I decided to slap on 35-37 tires with 4.88's, then my gas milage shouldn't be altered very much by the tires themselves. Am I right?

 

It will suffer less with good gears, than it would without 'em. Bigger tires are heavier.... if you went with the 35's, and 4.88s, you might actually get BETTER gas mileage around town, but, would suffer on the freeway. 4.56 and 35's would keep rpm right around where they are stock, and you would prolly drop a point or so on gas mileage. 33's and 4.10s would be pretty similar.

 

4.88's are better match for 37's or 38's. and like HeyYou said it wont suffer as much as mine has, but it will still suffer. 37+ inch tires are very, very heavy(my rims and tires weigh about 150lbs or so on each corner, and your motor still has to turn those heavy SOB's(albeit will take slightly less effort)

 

So 4.56 or 4.10 gears are better suited for the 35's? My usual driving consist of around town driving and some times a 10 mile trip up the highway (55-65 mph tops) to the larger town for some things (walmart, autoparts, etc)

 

I would go with the 4.56's. I do mostly country/city driving, 55mph speed limit and less, but do have to highway travel at times, sometimes up to 5-600 miles maybe 1-2 times a year. But do hit the highway at least once a week for 50 miles or so. I plan (when money permits) on going with 4.56's and 33's.

I looked at doing 4.10's but with all the towing and hauling I do, I felt the 4.56's are better siuted.
