2-speed 8-lug rear axle to replace 14-bolt??? - Pirate4x4.Com : 4x4 and Off-Road Forum

thecarman · 08-22-2002, 06:55 PM

Hey!

Is there a 2-speed rear axle I can use in place of the 4.10 geared 14-bolt in my rollback? 8-lug, about 63" WMS-WMS width.

I have been towing some heavy loads lately (http://triadfoundry.com/richards_pic...icles/tow2.jpg)

, so it would be nice to be able to split gears, and would also be nice to have the overdrive.

I know I could get a Gear Vendors overdrive unit, but I can' justify the cost, so if I could swap in a 2-speed axle cheaper, that would be great!

Thanks!
Richard

im not sure if any one makes a 2-speed light duty axle. a us gear or a gear vendors will prolly be your best bet. btw do you want to under drive or over drive splits?

Man we were breaking those trucks just loading cars on them. Thats why they've gone to using 2.5 to 5 ton trucks for roll back out here. You need to get a bigger truck to do that with.

I want Overdrive splits.

This is just a "hobby" for me, not my profession

, so I'm trying to keep it cheap. That's why I'd like to find something less expensive than a Gear Vendors unit.

If I was using this truck professionally, I might be able to afford something bigger (and nicer

). But I just use it once a week at the most.

That was the first time I towed two vehicles at once with it, and I don't plan on doing that regularly, especially with vehicles that heavy.

But it sure would be nice to have a gear in between 3rd and 4th for passing, and an overdrive for 4th anyway.

I'm curious - were/are you a tow truck driver by profession, and how did you see the trucks break (so I know what to look out for)?

Thanks!!!

The only 2 speed rears I have seen are 2 1/2 ton up. So upgrade to a rockwell

. They make 2 speed "brownie" boxes you can mount between your trans and rear diff that will double your gears.

Back in '78 I was between truck driving jobs and a friend managed a tow fleet in San Jose, Ca. I drove wreckers some and mainly was their mechanic. That was when they first strated coming out with the roll backs on a 1 ton chassis and the cradel wheel lift trucks. We were braking the beds on the wheel lifts and breaking frames on the roll backs. Now all the newwer roll backs I see are built off of 2.5 ton and bigger trucks. Later I ran a gas station and did tows/ recoveries out of Soda Springs, Ca. During the winter the best tow rig we had was an old holmes bed on a '53 GMC 2 axle X military 4x4. I'd put duals wheels front and rear on it and chain up all 8 tires. Sucker was "SLOW AS HELL" and smoked like a mother but it did the job when nothing else could short of a track.
