I have an AX15 trans that I wanted to install, but thinking I still may need to try and find a 4.10 center section to get my rpm's to a comfortable highway cruising speed.
Dumb question, what's the easiest way for me to tell if I have the "no-spin" locker? And what should the width be on this axkle from mounting flange to mounting flange?

Jack up both wheels with the transmission in park, and the front wheels blocked. Rotate one wheel. If the oposite wheel spins the oposite direction it is an open differential.

Anybody know what the factory spring rate would be for a coil sprung Eaton C20 LWB (base truck), so I can compare and get a slightly more forgiving spring? I also have aftermarket airbags installed on the axle so if I decided to load the bed down, I have extra help without the harshness day-to-day of these stiff coils.

1/2 ton coils are a direct bolt in and readily available. I hope this helps!

the 14 bolt disc brake conversion kits are a direct bolt on to the HO52/HO72. you do not need to use the 14 bolt hubs.
