The 4.88 mega thread!!

I will contact them and see if they price match. Worst than can happen is they say no and I wait.

edit- yep they said no. playing the waiting game to see what sales arrive during the upcoming holiday season.

 

There is a chance that what they have on the shelf is already REM polished so that'll be extra BUT totally worth it. Call and talk to either Serena or Joey. Actually, Serena may be off to SEMA but Joey should be there

 

Can someone with 4.88's and 265/75/16r post your engine RPMS at cruise? I'm wondering what they'd be around 65-75.

 

go back one page to post 147 - they are 285's but it should give you a good idea on 4.88's and highway speed.

 

I've read through this thread mulitply times and i never saw that post. Thanks!

 

@Lord Humongous is running a similar, if not that exact tire size. I am running 285/75-17's, so a 34 and at 75 to 80 mph, I am hovering around 2 to 2,300 rpm.

 

good post. i am thinking of doing this a little down the line, as I'm on 33's and my weight is adding up big time.
I like that you come up here to go biking... we would be friends. move to colorado.

 

Dude, I LOVE CO!! Believe me, I would move there in a heartbeat BUT, I have an amazing job here. The plan is however that after a few more years, move up there and work remote. In the meantime, frequent trips will continue to happen.

 

Its polishing of the gears.....Why does that matter? Generally you have a break in period for the first 500 miles. You should drive it 30 or so miles and then let the gears cool completely and keep doing this until about 500 miles or so. This naturally puts the gears through a heat cycle and basically polishes any burs or machining marks off the gears. With REM polished gears you can skip the whole break in period. I just changed my diff oil at 700 miles for the first time. I had no metal at all in the diff fluid upon inspection. I had REM gears installed

 

right on man. I practically lived at winter park this summer with all the biking i did. if you ever make it up here and want to hit some laps at the park for a day and camp, hit me up.

 

For sure man! Winter Park got me this year. Rainmaker hot laps, ended up breaking a few ribs.

 

dang man! that sucks! i broke my wrist this year on a fall too. lol.

I want to do this and have the money. Only problem, I can't find a shop that I would trust in SW Missouri.

 

At 80 mph I usually run about 2400 rpms and the truck almost never shifts out of 6th which is nice. The tall 6th gear ratio of .58 allows the truck to comfortably cruise on the highway with the smaller tires and it's a ton more fun to drive around town!

 

was wondering I have the automatic , 2.7 4x4 should I go 4.88s as well I have the skinny 33s and will be going to a 295 75 16 in the near future, your thoughts would be much appreciated

 

I couldn’t upload a video clip, however, at 60+ mph, the rpm’s were humming along at 2k and it felt as if it was right in the powerband. No gear hunting and I didn’t have to use my SSP.

 

What kind of gas mileage are you guys getting? REALLY thinking about having the gears swapped soon.

 

At 55 in 5th gear 1966 rpm, at 65 in 6th gear 1953 rpm, at 75 in 6th gear 2254 rpm
