What would happen if I put 4.56 gears in my stock truck? Would it work?
Mike
assuming you're not kidding...
Yes, it will work fine. You'll be able to actually drive on the road without redlining anything.
I'm not kidding, just not learned, ha. So what is the drawback? Is there one?
Mike
You lose the wow factor of having 5.87's and the cost could be a drawback if you're a cheapass like myself. If you never drive more than 45, I'd say to not go to the expense.
Chris
Unfortunately, highway driving is a concern of mine because my truck has to make the occasional trip between central PA and Maryland. At 45 it takes me about four and a half hours. What would my top speed be if I changed the gearing?
Thanks
Mike
depends on what you want to rev it up to. w/4.56's and a beat 460 in my 725, on 35" actual diameter Swampers, I got about 3200rpm@65mph.
There's no real drawback except the cost. R&P isn't a killer, but installation if you don't know someone IS... Kinda pricey. 5.87's are nice and low but maybe a little too low for normal use.
My engine is stock and I'm rolling on 36" humvee tires. It would be nice to actually start in first gear and be able to keep up with traffic in 4th. For those that have done this, did you buy from Randy's ring and pinion?
Mike
I have 4.56 in my truck. The rest is stock. Rides and runs great! I would Highly recommend it if you plan to use your truck for anything but strickly offroad.
First will still be too low. I wanted to downgear my F100 with T98 and be able to get overdrive revs in 4th. With 3.00 gears first was too low and second was a little high for starting. So don't expect miracles in that department.
Chris
... oh and yes My were puchased from Randy's Ring &m Pinion in Everett WA. Total cost was $952.86.

wow that's more than I thought it would cost. Is there somewhere I can read what all those symbols mean? ha. Other than Dana 60 and 70 I don't know what that says.
Thanks,

Mine were purchased from Reider Racing in '96 for... about.. $609 bucks, that's for the R/P, install kits, and the new bearings. I don't know how much that's changed since then, I'd guess a bit, but probably not $300 worht LOL.. here's the breakdown:
4.56 rp D60--------189.98
4.56 rp D70--------198.95 PLUS INSTALLATION, TAX, SHIPPING.
install kit D60------60.00
install kit D70------70.00
FYI if by some miracle you got tall enough gears in the axles to make first useful on the street, you won't have enough power to use 2,3, and 4. These trucks have a "granny" first, it's extra low. Same thing w/SM465's out of Chevy's. I got to about 15mph, redlined in 1st. Just use 2nd and be glad they even gave you THAT many gears LOL.. enjoy.

For those of you that have 4.56 gears, did you put em in yourself, know a friend that can do them, or pay a mechanic? If mechanic, what did it cost ya, hours of labor? Just curious.
Mike
I know someone in NJ who sets gears for $150 per axle. He's really good.
Mike: you CAN do it yourself if you want to take the time to learn how... backlash is critical if you want them to live. I'd take it to a shop if it was me.
