I only show a lock right locker for these 9.25"

And voila....we have 8 bolt, 33 spline cv joints

bought a CV axle for the 9.25ifs 2010+ - has correct 8 bolt pattern at diff.
and another cv from a pre 2010 9.25 ifs vehicle- has correct 33 spline at the wheel hub , last thing I need to check is if itll work with lowering spindles. The outer joint seems more tapered I dont think itll be an issue. I threw the spline in from the outside to verify it matched
And stock axle at bottom. May need a spacer but I think they make cv spacers for lift kits should be easy enough. where the axles mount on the diff the 9.25 is about an inch wider on each side than the 8.25

Couple spacers courtesy of cognito, on the shelf they have 5/8, 1.2", and 1.8", grabbed 5/8 for passenger side and 1.2 for driverside along with new hardware for each.

Amazing work!

Been in a working pretty good, went ahead and ordered a new passenger side axle housing, threw some paint on it, new bearing and seal. Also noticed upper ball-joint nuts were real close to the cv joints, maybe a little rubbing. I ground them down a little bit, put them back on with some locktite.

Once again, amazing work. I'm interested in doing the same but with a torsen diff in the the 9.25.

Wanted to ask you a few questions about the install. I have a 2011 silverado and wanted to do this swap as well. From what I can see in your pictures it fits with a few modifications? What did you have to modify on the housing? Does it still mount up to the same spots?

both differentials mount to their respective frames with a bushing'd bracket.
- the 2500hd uses the two bolts on the passenger side, and three bolts on the drivers side.
- the 1500 uses 2 each side.
- I dont believe the 2500 brackets will bolt to the 1500 frame, they came with the front diff i bought but i diidnt i even try them because they were way different.
- the 4 bolts on the differentials do line up on the 1500 brackets, however the 2500hd diff is slightly wider, prob 1/2". the diff to those brackets is a solid bolted connection. there is enough play in the bushings (to the frame) to start all the bolts and just suck it up.
- I cut the 3rd mounting point on the drivers side off, it hits the 1500 bracket that mounts it to the frame.

Im starting this swap in a few days! 5.13 gears but Im going to have custom length cv shafts made. Sucks that no one has plans on any r and d for an airlocker or electric one.
