Currie is installed

[Jakedog]

I finished installing my Currie rear 9" yesterday. Took a 5-6 mile drive today. I'm glad I went with the 4.56 gear ratio. I went back and forth between 4.11, 4.30 and 4.56 before I ordered the axle. I finally decided to go 4.56 after lots of reading on CB.


Some suggested 4.88 and 5.13, but both seemed too low for my needs. I run an np435 trans and my tires measure 34.5" on the wheels when they're not mounted on the bronco. I love this set up, and it's much more fun to drive.

For those of you with automatics and 35's I would definitely listen to the guys on here when they say go 4.56 or lower.

Jakedog, I sent you a pm but I see you have commented on those of us with a c4 and your recommendation. Thanks, I have a c4 with 35's and have been back and forth with this decision. I have 4.30 gears ready to be purchased since I kept thinking 4.56 on interstate would tach a bit high. thanks again for you recommendations.

Not sure if you've seen this but it's worth a look:

I asked for advice on gear ratios a couple of months ago and I received some good advice. Here's a link to that as well.
