Hello All...
I am looking to get new gears installed in my 06 4x4. I currently have a 4.6L with 3.55 gears. I am running 35" Tires, 3" Levelling Kit, Edge Programmer, K&N Cold Intake and a Flowmaster Super 44... I tow a 9,000lb toy hauler. Before the tires it wasn't too bad. After the tires it totally sucks. I think I am going to go with either 4.88 or 5.13 gears.

Question 1: Any suggestions between the 4.88 and 5.13 Gears?
Question 2: I am in Southern California. Where should I purchase and have the gears installed?
Question 3: What are everyones thoughts on a Detroit Locker? (Only Considering this - A lot of extra money!)

Thanks in advance everyone...

 

Unless you do towing very frequently I would go with 4.56s. The 5.13s are way to high a ratio for 35s and the 4.88s will still be high but if you tow all the time it might be worth it. You need to take into consideration what your RPM's will be at 70 or so MPH.

 

if your anywhere near san diego or el cajon give san diego gear and axel a call they did my ranger before i sold it and did a damn good job told me about the teflon coating what oil to use and to bring it back in if i have any problems or questions

 

I have decided to go with 4.88 Gears Now..... These will increase my RPM's at 70 mph from about 1700 to 2300..... Not too bad... I am almost 1.5 hours from San Diego... Anyone know of a good shop near Riverside, California?

Thanks Again.....
