We also have the carrier bearing shim kits ready to ship as well with the purchase of the LSDs, just let us know if you need them or not, these would be required to install the LSD, you can also buy the full bearing kit as well if you want to replace pretty much everything back there...
Note: LSD's do not come with shim kits or install kits, they come as is just plain old LSD in the box.
Most driveline shops will have the shims and shim kits avail or access to them, they will just add that into your install bill as "shop supplies/expenses" most of the time, we use the Unitrax kits, these kits run about 65 bucks and are not too terrible on the wallet, the bearing kits however are NOT required as the bearings hold up extremely well in these rears from what Unitrax has told me as long as the rear's have not been neglected...but they are always good to have on hand, those are a lil more expensive but are a complete package. So for all the guys that bought the LSD's, sorry if I didn't explain this earlier, hopefully you're not attempting to just install at home in the garage as this is a pretty extensive install and the proper tools are required. Just wanted to clarify as a customer brought this up to me recently.
Another note, please use additive free synthetic gear oil, do NOT buy the stuff with LSD additives as it is made for clutch based LSD's, this is a gear based LSD....just a reminder
