Gears for my E55
I've done some searching and can't find any info on what 3.06 gears are compatible with my E55. I'm sure this has been discussed but can't find it. Any help would be appreciated!
I've been doing Ford rearends for 20 years but new to the whole Mercedes world.

Srt-8 charger, challenger and 300c all use the same 3.06 gears... Gotta b a srt8 tho.. Hemi cars went down to 2.73 or 2.92.. Can't remember off memory.. What's the factory rear gearing in these cars? Just curious...
And better gearing/ taller gear will do exactly the opposite... Cut your top speed down, but will roll through the gears quicker and much effortlessly.. More gear is always better.. TRACTION PROVIDED

Well with all the low end torque and the aggressive tranny gearing..... Naaaaahhhhhh I'm impressed... But the Chrysler 3.06 being a direct swap, should make for a nice little increase in acceleration and I'd bet a good bit difference at the track

You can also swap the entire pumpkin from an SL55/E63/SL63, and then you don't need to bother with the labor of opening up the diff case. You can pickup entire salvage diff's off eBay for cheap.
I did that and put in an E63 diff that had the factory LSD. Factory LSD is not quite as good as an aftermarket LSD, but works fantastic since I paid so little for the entire diff and install cost was really cheap.
If you go that route, search and you'll find many threads that list what gears are in the various AMG models.

I think the gears with the stock converter would be a huge improvement and traction wont be too much of a issue at the track. I may even take my stall out and have it tightened up since I now have these gears. also with the gears I went back to stock shift points no need to rev the hell out of it now.

SRT8 has 3.06 but they have 7 speed. More gears that's the main thing E55 has 5.
With stock gears the E55 screams to the 1/4 closely topping out 3rd gear. for 1/4 I think it's actually perfect. In drag racing you want to scream through the traps at or even past peak hp rpm. That is a fact. If you tighten up the gears it will shift to 4th and by the time you reach 1/4 you wont be at peak rpms. Now a 1/2 roll race I will take the shorter gears and for daily all day long. But, I do not see a huge benefit from shorter gears for 1/4. Probably will go slower and scratch your head.
Sure you can go to a larger diameter tire to compensate and try to keep it in 3rd. But, now you just put a huge honkin tire and adding weight to the rear wheels or even go to smaller diameter tire to try and rev out 4th. But, you are chasing your tail in my opinion.

If 1/4 mile ET is important, then going to a 3.06 gear probably won't help. That's why I left the 2.65's in when I did my Wavetrac install. Any increased acceleration will be offset by the time it takes to do that 3-4 shift.
If you are after only "seat of the pants" results, then 3.06 would be a good idea. If you want to optimize your 1/8th mile or 1/2 mile ET, then you need to do the math and find the ratio that has you crossing the line at max RPM in whatever gear you would be in.
