okay so correct me if im wrong, im using this gear calculator on this website http://www.ringpinion.com/Calculators/Calc_RPM.aspx . The gear ratio for my ring and pinion will be 3.73, with 37" tires and going 75 MPH my 4BT RPM should be roughly 2032RPMS . The Economical range for the 4bt is...

okay so i got the measurements for both WMS to WMS of the stock front and Rear Axle. I got about 70 3/8 inches for the front and for the rear i got 70" inches. There both probably 70". I measured from the drum to the other drum. i also measured the rim and got about 8.5 inches wide. the rim has...

so far a rough quote was $3,000 for the rear axle, and about $5,000 for the front. But the price will change once i tell him the axle only needs to be shortned on one side, that price was for both being shortned.

Correct I'am ordering axles, i measured the distance of the perch spring locations , and from center spring perch to center spring perch for the front its 29" inches. Still have to measure the rear, and measure the rim and WMS to WMS for both axles, so that I order the correct sizes. Thanks for...

When narrowing the axles is it necessary to add 4 inches to give me more of a selection for tires and rims, I can make up the difference with back spacing and offsetting

No I haven't got a chance to take the tires of to get a good measurement of WMs of the m37. The axles from the m1008 are not just bolt on if I remember correctly you have to move the perches to the outboard side of the frame on the truck. I didn't want to do that, I figured I get them shortened...

Would the 14 bolt be any different? Do you know what is the WMS for the M37? Thanks

Hello everyone, haven't been on here for a while. Finally going to get started on my project next Month. I decided that i want to order both axle for the front and rear. They would both be dana 60s . I figured I would try to keep as much of the original look of the truck. Today i was able to...

No i guess i took your words into consideration :) and i dont really like cucv they look ugly imo lol. but i was getting those measurements from a vendor that carried some of them. But i still dont understand what you mean by the wheels are too narrow for the tires? is this because he tried to...
