Rear Trailing Arm Bracket - Left - E36 E46 E83 E85 E89 - 33303411877

This part is listed by BMW as BMW part number 33303411877 (33 30 3 411 877) and is described as Genuine BMW Bracket Left, 33303411877, for the E36, E46 3 Series, E83 X3 (first generation), E85 Z4, and E89 Z4.

If you are overhauling the rear suspension, rear trailing arms, or reinforcing the rear chassis of your E46 3 series or other chassis that share the same rear suspension design (E83, E85, E89 chassis), then you may want to consider refreshing the steel "pocket" brackets for your rear trailing arms. On cars with high mileage or heavy track usage, this bracket is known to literally rip right out of the chassis. It's also susceptible to rust and general collision damage. 

This is a brand new Genuine BMW replacement rear trailing arm pocket bracket for the LEFT side (driver's side rear, on US spec left hand drive vehicles). It's found on all E46 3 series (1999-2006 generation), as well as the first generation BMW X3 (e83 chassis, 2004-2010), and BMW Z4 (2003-2018). 

BimmerWorld Tip: If you are repairing or reinforcing the rear trailing arm pockets on a 1992-1999 E36 or E36 M3, make sure to get our reinforcement kit, BimmerWorld part # 100.33.536.0012 . On E46, E83 X3 or E85/E89 Z4 models, the reinforcement kit isn't necessary (or compatible), but we do recommend a solid stitch weld (versus the stock method of spot welding) which will help strengthen this chassis attachment point. This is a must on track and race cars!
