plan to re-gear my truck after my 37s go on. plan on a set of 4.56s front and rear plus some aftermarket diff. covers. had mag-hytec on my last truck(GMC) and it was a quality piece so i want those front and rear on my Ford. not sure what covers will work as some wont fit with aftermarket suspension. just wondering what ring and pinion brand to go with along with what gear oil and diff. cover brand. and any other recomendations on the install. thanks
Randy's Ring & Pinion Lots to chose from. Some are for 10.25 others for 10.5 rears. If your going for a open or maybe a LS unit you shouldn't have much of a problem finding a set. If your looking to put a locker or a real LS unit, then the choices get limited.

Just had Yukon 4.56's installed and am told they are one of the best. I got them from TruckToyz which is a sponsor of this site. I was very pleased with the the price and service. Hope it helps.

4.56's is high for 37's. I went with 4.30's and its more than enough.
That's not necessarily true. Gear selection depends on what the truck is used for.

well i had 4.88s in my last truck(duramax with allison 6-speed) and it was perfect...im still undecided on the 4.56 or 4.88...now i jus need to know which covers will fit with my new suspension...
I have 22's on 37's, went from 3.73 to 4.56, I will tow a toyhauler once a month.
If you do more towing, you can think about 4.88's, but the 4.56 work for me just fine.
I went with maghytec diff covers, big fins and hold alot more fluid. It came with its own dip stick

Depending on the model year and how your steering stabilizer is configured, you may have clearance issues with any aftermarket front cover. On mine, I had to grind down one of the fins to clear...

my stabilizers are side by side in front of the axle but the way they set they should not interfear with the front cover. i dont think atleast....i hope not. i think i will stick with the 4.56s and i would like to use the mag-hytec covers also.
got my kit on and fixin to do my gears....anybody know what diff. covers will work with the rough country dual steering stabilizer kit??? the bracket uses 4 mounting bolts and two of them are two of the bolts that hold the diff. cover on.....i know most aftermarket covers are thicker than the stock ones....i just need to know what covers will fit with the setup i have...any help will be greatly appreciated. thanks
Being out of my comfort zone causes me to ask this question---How do I know what size R&P set I have? I have a 2004 CC dually with the 6.0L, automatic transmission, and 3.73 rear end. I would like to go to a 4.10 to get better towing ability.
