One of the last things my truck needs is trans/TC work. The rear wheels locked up on the highway while being towed on a dolly. I am assuming one or both is bad putting me in the market for a trans and TC. A buddy of mine decided he didn't like the Ashcroft in his truck so I bought it off him, haven't put it in yet (it was a good deal/cheaper than buying an OD).
I have been restoring an otherwise standard 71 NAS IIA 88 wagon. It has the standard top (not safari or alpine windows) so it may be considered relatively light weight.
I already purchased a set of 16" wheels and a set of 235/85 tires (31.7") before the Ashcroft was even in the picture. I was thinking about it now and figured this combination would probably be overkill for the 2.25. Most of my driving is done in the NE, not the flat lands. Has anyone used the Ashcroft with shorter tires (maybe a 29"/30")? I figured that might give a small enough reduction in weight/gear to still be usable.
Some quick calculations with thanks to TeriAnn's page.
65mph with Ashcroft 31.7" tires: 2,817 rpm
65mph with Ashcroft 30" tires: 2,977 rpm
65mph with Ashcroft 29" tires: 3,080 rpm
65mph stock TC 31.7" tires: 3,720 rpm
Another thing I have been considering is the weight of the tall 31.7" tire (a lot) and the 16" wheel combo which weighs more than a 29" tire and 15" wheel combo. Meaning there isn't just a reduction in gearing, but more weight to get (and keep) turning with the taller tires.
My truck will probably be used mostly on road/light off road for now (fresh resto, don't want to beat on it on the trails just yet). I realize the taller tires give a proper LR look and a lot more ground clearance too but I'm not too worried about it yet.
As of right now I have a set of 235/85/16 tires, a set of 16" wheels, and a set of 15" wheels so I am open to options. And using two different on/off road sets down the road. Thanks for any help.
