Maxidyne Posted December 31, 2018 Share Posted December 31, 2018 It can get more complicated than that... Several years back I researched upgrading from the 12k# front axle on an MR. Turned out the next rating up, 12.6k# IIRC, looked the same but had a more thorough heat treating. 1 Quote Link to comment Share on other sites More sharing options...

Vladislav Posted January 1, 2019 Share Posted January 1, 2019 There's also setup with a torque rod from the RR carrier housing to the right frame rail (like airrides have) on Camelback suspensions starting from sertain raiting.

m16ty Posted January 9, 2019 Share Posted January 9, 2019 I've got a set of 65K rears under my truck. Never really have paid much attention to the details of it. The axles are physically bigger than the smaller ones, the trunnion mount is massive with lots of bracing, and it's on walking beams. 1 Quote Link to comment Share on other sites More sharing options...

If you have newer version of the housings (post - 2006/2007) then you can use at higher rating. On 1/8/2019 at 10:28 PM, m16ty said: I've got a set of 65K rears under my truck.

You have a Cast ductile axle housing @ 65K GAWR with CRD95/96 carrier. This has been in production since 1945. 1 Quote Link to comment Share on other sites More sharing options...
