The 4.88 mega thread!!

Love them. Major difference over stock 4.30s.

 

Just ran 230.5 miles at 85mph 2800 RPM and averaged 14mpg. Still had 1/4 tank left.

 

Had my 4.88 REM polished gears installed almost 2 weeks ago now, drives great.. Putting 315’s on next week

This was last night. Over 100 miles on 1/4 alternating speeds between 70 and 80 for the break-in period. Ended up getting 340 miles on that tank. Stopped to fill up with 1/8 tank left.

 

Have been considering the upgrade given given all the good reviews but not likely to go any larger than 285/75

 

Thank you for this write up. It’s because of this nicely detailed review I recently pulled the trigger on new nitro 4.88 gears. I got them installed 2 days ago and still in the break in process. I did not opt to REM finish the gears.
So far I have been babying the truck but it pulls so much better now. It’s night and day! I have 700lbs of added weight. 33 inch tires, Armor, winch, roof rack, spare tire carrier with full size spare and rim, sliders, lights, high lift jack, axe, snatch block, etc etc. and I’m getting 19mpg local before was getting 12mpg. Haven’t tried the Highway yet but I’m sure it’s going to be a lot better.

I definitely recommend the 4.88 gears. If you are in SoCal in the Los Angles area go to Hooper’s rear end. They did a great job on my taco and the gears are quiet no noise or humming/howling sounds.

 

I was looking for a place near me and although i hate driving to LA i will trust your recommendation. Whats their price and turn around time i have gear set. Thanks for review

 

They charged me $1100 for the labor and did the front locker no charge. They had it done in a day and a half although I have seen them complete work in a day since they have multiple lifts and workers. They are good and know what they are doing.

 

hmm, this sound like a completely viable option to do on my truck. The past few upgrades have really sucked the fuel mileage down on the old girl.

 

Great im gonna schedule with them! Have them do the ecgs bushing hopefully at no charge lol

 

What is the cost everyone is paying to have this completed? I just received a quote for 4200USD to get this completed. Is this in the normal range? Parts were about 1500, the rest was labour, seemed a bit high to me, but i am out of touch time to do regearing on differentials.

$1850 all-in for gears and install (front and rear and ECGS bushing) at @ECGS in Raleigh.

 

That's quite good! Curious how long the install took. Day? Day and a half?
Raleigh isn't far for me, however being without the truck is costly.

 

K, that seems a lot more reasonable, as much as I like that shops work, I am not paying shop rates for an install that charge out more then I do for my work. Mechanic work is getting down right crazy these days.

 

I drove up from Palm Beach last Thursday night, arrived at ECGS around 0430 local. Slept in the truck until they opened. They took the truck in at 0800 and I went to the hotel. I returned to the shop around 1500 and was on my way home by 1615. Roughly 8 hours for them to do the front and rear.

 

They were gonna do my ECGS bushing no charge but I had an ARB air locker so didn’t need to do the ecgs bushing cause arb front lockers don’t use a needle bearing.
