does anyone know wear I can get a spool for the rear axle?

 

Check out Randy's Ring and Pinion.

Spool

 

We're assuming this will be an off-street truck only???

 

Wow! thats a little bit more pricey than I thought it would be

It for my pulling truck, The rear end that I had in it one of the axle tubes got bent last year at a pull they made me take my traction bars off and it bounce real bad, and then I broke the locker and a axle shaft two weeks ago so I got a junk yard rear end that I was told "it has a locker in it" but it has no locker. I thoght about just welding the spider gears together and seen what happens

 

Nothing is cheap for these axles...

Except the good 'ole Lincoln Locker.
