glad it worked out for you, let us know if your gas mileage changes any

 

I'll keep my 2000rpms at 70mph, lol. I bet it runs like a raped ape, though.

 

I do about 2350 rpm @ 70 on the interstate with my 4.56's. Overall, I have been happy with mine as well.

 

I put 4.10's in mine a while back, and I love it. Could never imagine 4.56's unless I put larger tires on it.

While mine is manual... it's very easy and fun to drive. I can go from 2nd to 4th for city cruising, and highway literally from 2nd to 5th. Still gets decent mileage.

Makes towing and stump pulling very efficient.

 

Overdrive in a 4R is 0.70.

 

That ain't bad dewalt. My 5.4 would probably be around the same RPM with 4.88s This really has me thinking about doing gears now

 

If your doing stop and go and hill climbs, gears are definitely worth it. Especially if you are like me running big M/Ts that will never see the fields and mud. I would swap gears if I planned to keep it for 10+ years. MPG increase down low would totally be worth it. Less strain on the 'not-so-bulletproof' 4r75e would be good too.

Now its time for some 305/45-22 Terra Graps now!

 

I bet that thing gets up and go's! I'm running 4.56 Yukons, but with 35" tires.

 

Year's ago it was common to run even lower gear's...4.88's and 5.13's sometimes. This was with 4 speed's with no overdrive gearing. Car's sounded like a bunch of tractor's!

 

Did you get another new truck?? Sheesh you're the next Desert Dawg LOL!

 

Hi Gbctrdrman,

I see your in East TX, where did you get the gears put in? I'm wanting to do the same and am very seriously thinking of 4.56 as I hear too many mixed reviews on Motives 4.30 gear whinning.

THanks,
Rob
Humble, TX

 

Not to burst your bubble, but GBCTRDRMAN hasn't had any activity on the forum in over a year, so I wouldn't expect a response. You'd have better luck starting a new thread of your own instead of resurrecting a year-old thread.
