So question with the 4.10 LSD and 235/75 R15 will I get worse gas mileage or better or the around the same that I did with 235/75 R15 on the stock 3.73 open

Around the same. You might see slightly less. And it's going to feel a little better to the pedal, going to move a lil easier. But you will be turning higher rpm at cruising speeds.

Ok I'm also adjusting the timing to 14° and gonna be putting a K&N airfilter and a glasspack on it as well with the E-fan if I can find a good one

You will notice a difference fursur. Let me know when she's up and runniing and ill jam up to the lake and we can hit some trials. There are plenty near you.

Sounds good not sure when I'll be doing the glasspack but I'll be buying the airfilter on Friday what's the best E fan for a first gen ranger/b2?

Couldn't tell you. I don't run one. Honestly if there isn't anything wrong with your clutch fan I'd keep it. I'd use the money and just completely tune up the motor so she runs awsome and won't ever leave you stranded. Or mabey some nice aftermarket shocks for when you do want to go wheeling.

I was gonna do E fan for the better fuel economy since I'll be going to utah soon and I was gonna do a tune up as well shouldn't be too bad cost wise I heard the 96-07 Taurus fan would work amazing so I was thinking of hitting up on of the scrap yards down in bako one of these days

Are you doing a full Air Intake or just a drop in filter ?

I have a full intake already just need the mas airflow adapter I'm having a hard time choosing what to run because the Bronco pretty much has a factory cold air intake but I don't like how low it is on the frame where is can suck in water

If you after economy the 4.10 is going to cancel anything out the efan with help. If you put an efan on and the rear diff you prolly be getting the same mpg you were before.

You have the 2.9 right ?

Yes 2.9 which was a dog with the 3.73 gearing trying to turn the 235/75

I have a 3.0 with 3.73 and 31x10.5x15 tires. Mine scoots around just fine. You do have to remeber your driving a truck and not a race car. I know my truck like to be in the 3-4500 rpm range so when I'm driving and need any power I just make sure to keep in that area and it's more than enough. It does help having a 5spd.

Yeah mines a 5speed as well but compared to the ranger that the 4.10 are coming out of even with the ranger being a auto the ranger felt a lot peppier granted it did have some puny 215/45 r17s on it

Main reason I'm swapping rear ends is for the LSD since I go to utah a lot during the winter lol

You will enjoy the sway. The LSD is gunna make a huge difference. If you ever need one I have a welder to.

this is the intake kit I have that I'm planning on running eventually
