Non-M HD Differential Mount Kit

Another E46 part designed from the ground up by SLG that nobody else offered (until they copied it)! This is for when you need the next level of protection from subframe and axle failures! 

With our kit, enjoy the PERFECT fitment, making welding quick and easy! 

The factory E46 differential mounting leaves so much to be desired for many reasons as explained below:

• Power is unevenly distributed through the subframe to the vehicle floor, causing twisting and the notorious cracking of E46 subframe mounting areas
• The diff is held with little leverage, and twists more than you think. With high power and/or clutch kicks we have seen bent front bolts and broken rear mounts in many cars
• The moving diff contributes to blown axle CV joints and in turn, more broken axles
• We just plain broke off the rear mount on our 330. Race car problems!

So, take advantage of what is a power capable diff (up to ~450hp) and avoid upgrading to an M3 subframe/diff setup. Our kit bolts between the diff and the diff cover. It then attaches to the subframe via two weld-on tabs.
