Rockwell rears

Is that what they call the single axle version of rt40 145? If so we have a million on 3.91s. My dad and a few others like em better than the top loads on the 99 ch

What do you want to change em for?

 

Off topic stan but on the the south side of pocahontas Arkansas on the east side of us 67 there is pete 372 sitting there and has been for a while ...and ! ..its an ex harley Davidson truck ( black and orange) looks to be in pretty decent shape.

 

Personally Ive learned to enjoy the Rockwells. I was first introduced to them back in 98 with that FLD120 which had a Rockwell 9 on Rockwell Rears whatever ratios they were. That particular Dowdy truck showed enough beef to not come out of top gear in the midwest up to 72 at all. Which was where I had trouble with in the past with previous trucks unable to hold gear in some of those hills.

I think some consider the midwest a bit easy. I have respect for some of their hills for what they can do to a semi.

I had a couple of other Rockwell trucks in the mid 90's and they were very good. Nothing but good things. Now if I could get them to show me a 13 speed double over or under with the same structure, then we would really have something awesome. You could do alot more with a 13 than just any old 10 or 9er.

 

I haven't been around long enough to tell you about any issues or known issues.

The cheapest option might just be a set of cutoffs. Ds 404 or 402 cant remember which but should be easy to find.

Or

If you can source the parts at a good cost leave the rears alone and find a RTX 14609B and the back half of a 14613 and have .62 in the final split. With 3.91s and 22.5LP 65mph is 1400 so with 4.10 i believe 1600 is where you'd be at. But i think a set of cutoffs would be cheaper
