This truck needs a serious motor.

@2253benjamin Yes! The big block fule injected 502 develops 425 ft-lbs at 800 RPM and 550 ft-lb at 3600 rpm. A good diesel would be twice that torque. But I opted for the gas motor due to weight distribution. When I tow my 13,000 pound boat I wish I had another 200 horses or so. One of these days a ROOTS type blower (develops boost at idle) is an item I want to add. I do love the diesels though. I have a 24 horse Yanmar on my John Deere. Love it.

What are the specs on that axle? Shafts look huge!, Is that a 1550 steering u-joint?

[1966ih]

The axles on the FDS 75 are 1.75" dia. The u-joint in the steering part of the axle are much bigger than 1550s. They are a "wing bearing" type of u-joint and the Rockwell part # is CP58WB-DWT ($98 each!!). The u-joints in the driveshafts are 1710 series and take 3X the load of the 1550 series.

how heavy does a rockwell 2.5ton really weight? Great video you have here and very well explained in details. Keep up the great work.

[1966ih]

Well, this is NOT a "military" 2.5 ton Rockwell. it is a slightly stronger commerciql version and has a standard Hypoid gear set instead of a "top loader" spiral bevel gear set like the military. This axles is rated for 7,500 pounds and weighs about 914 pounds. Thanks for the compliments.

Wow thats incredibly cool!!, Those axles must be able to handle almost any tire size and horsepower rating. Thanks for replying.
