rockwells on a toyota.

[YODAWILL]

I was wondering if you can run rockwells on a toyota with leafs front and rear and if so does anyone have pics.

[jimbo74]

yup

pirate has pics.....

[NorCalToy]

or a person named "6.72:1" has a build thread on here he running rockwells with leaves.

build is under rig gallery

[Wermz84]

Well, he put them on.  But I don't think it has ever driven yet.    I have been waiting.


Edit:  gears, gears, gears.

me too!

and the Rdubs let you go really low in gears dont they? like 8-9:1 or close to it?

[WHITE_TRASH]

Well considering the guys name is 6.72:1 what do you suppose the ratio is in a rockwell?

Hmmm I wonder.         Haha!

[YODAWILL]

So I read up on his truck its nice, What I'm wondering is can you drive that on the street will it go 55-65
and will a 22re make go that fast and how many different 2 1/2 ton rockwells is there it seen like there is more then 1 and if so what is the difference between then I thinking of going with a set but I know nothing about them.

  Thanks.

you need to do some research, rockwells are not street legal.

You probably could go 50 mph but your RPM's are gonna be pretty high with 6.72 or 7.17:1

I would say a rockwelled toyota isn't intended for street use, trail only.

It's like saying, "Hey can I put 54" boggers on my toyota and drive it at 70 mph?"

Sure you can, but I wouldn't do it nor would I recommend it.

i meant more of "whats the lowest  you can go?"

There are a few different Rockwell axles. There is front loaders, top loaders, planetary, etc.

The most commonly used Rockwell is the 2.5 ton top loader.  They have 6.72 gears and that is all that is available for them. Randy Ouverson is currently building aftermarket thirds that will accept both 6.72 and 4.89 (IIRC) gears but they are still in the developmental stage.

Top Loaders are what came in the military 2.5 ton trucks and there is no reason they can't be street driven. However, I wouldn't recommend running Rocks on the street. Because of the 6.72 gearing, you would have to run at least a 44" tire to get the RPMs close to factory @ 65 on the freeway.

With a 44, you will spin roughly 300 RPM faster than stock @ 65. If you were to run a more reasonable street size of say a 39.5, your Rs would be about 600 higher than stock.

Thanks for the info guys this helped alot.

whats the biggest a stock 2.5 ton rockwell cam handle? (tire size)

I've seen people running 54s with rocks.

thanks for the answer 

that would be awesome....i now have realized my end goal...

All depends on how you drive and what kind of power you're putting to the ground. For stock Rezepa shafts in a front steering application I'd say a 40 is decent and a 42 is getting questionable. For stock u-joint shafts in front I'd say you could get away with 44s.

For a rear steer application I wouldn't run much more than 42s on any stock shaft and I'd take it easy @ that.

You could definately beat on a rear steer axle with 42s and Ouverson's Alloy replacement shafts. Probably get away with 44s as well.

Anything bigger in a rear steer application I'd say you need Ouverson's 2" Alloys.

[Shamb]

a typical rockwell has axle shafts about the same size as a dana 60.

pretty beefy.

look up Dan Dibble's old rig, he put aftermarket 40 splines in his   

[freds40]

they're actually Ouverson's 2" Alloy 47 spline shafts.

A 60 has 1.50" shafts and a Rock is 1.61 IIRC.

[NorCalToy]

so a rockwell really isnt that much stronger than a 60?

[WHITE_TRASH]

Stock for stock not really.  But as soon as you start modding them the rockwell shoves its stub shaft up the 60's hub and goes to town...

Yup. A stock Rock u-joint shaft has a static load of roughly 1,600 ft/lbs more than a stock 60 (30 spline). Add 35 spline outers to a 60 and those numbers come a lot closer.

For $1000, you can get Ouverson's stock replacement 16 spline Alloy shafts and they are rated @ 3x the strength of the stock u_joint shafts. If you really want to step up, you can get the 47 spline 2"ers. Last I had talked to Randy, he couldn't give a figure on strength of the 2"ers because no one had broken one yet.

I have driven it, but not that far. It needs a little TLC to be complete, but right now, it is in storage for a year until I can afford to build a new shop at my new home....

  It Lives!!      Right on.  Good luck with the shop build,  let us know when you get going again.  :thumbup:
