My truck is fresh off having 4.56 gearing installed from ECGS, it drives like a dream. Effortless acceleration with my 37”s (essentially 36”s) smooth shifts, and power without downshifting. I have to say I’m in love all over again. Of course I’m still in break in phase so I’m being gentle on the throttle - none the less it pulls without much encouragement. There is a little bit of gear noise, almost sounds like mud terrains, hopefully that goes away with break in.
The first question half of you will ask is “Why not 4.88s”, well simple. First I never plan to go over 37s, the extra half inch of clearance with 38s isn’t worth the cost difference for my purposes, and I dislike how our trucks look with the lift kits when you go over 38s. Secondly, I drive a lot of highway 80-85 MPH, I didn’t want my truck running 2600-2800 RPM for hours at a time. Third the fuel economy increase is very nice.
Take it with a grain of salt because I was driving gently, but I was also in heavy stop and go traffic, but my average fuel economy returning home was 3MPG higher than normal. Again ‘Heavy Stop and Go’ but also ‘Driving Gently’. I’m not going to make a final say on that front just yet but preliminary results are promising. The few long stretches of road I did have were averaging 15–17MPG. Averaging for a DIC total of 13.5MPG on the whole trip, including stopping for 20 minutes.
Outfitter bushing kit: the installer was reasonably apprehensive about installing the bushings, or more over removing the old bushings. Fortunately he did go ahead and get them changed out for me. The difference is noticeable, the entire truck feels more solid, clunks that I had gotten used to are gone and it’s actually throwing me off not hearing them.
I’m excited to get more time behind the wheel once the monsoon ends.
I am very happy, upcoming changes will be a redhead steering box, a couple small front end items, and a tune.
