BMW has long suffered issues with rear shock mount blowout on M3 and non-M 3 Series models dating back to 1984 with the E30 chassis. Little changed over the following two decades, and E36, E46, and Z3/Z4 models are also prone to this style of failure. After striking a pothole or another seemingly innocuous obstacle, a clunking from the rear emerges and handling becomes sloppy. Your shocks have blown through their mounts. Enter the Ultimate Performance Rear Shock Mount Kit from ECS Tuning. Not only does their industry-first design alleviate the blowout problem once and for all, but allows rear dampers to fully articulate, for the best possible damper performance and longevity. They accomplish this with no noticeable increase in noise, vibration, or harshness (NVH) thanks to their unique rebuildable polyurethane isolation. The poly bushings not only keep NVH to a minimum, but they also reduce impact loading on the bearing, improving bearing life over full solid mounted monoball designs. To further improve bearing life and longevity, this design incorporates a lower dust seal to keep road debris, grit, and other contaminants out of the bearing. These are one of the best rear shock mounts available, and the last you will ever need. Features: Maintenance-free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation Lower dust seal for improved bearing life 80A polyurethane isolation bushings for NVH control and improved bearing life Accommodates 10mm* Fully constrained shaft mount makes blowouts impossible Hard anodized 6061-T6 construction Class 10 black zinc plated studs New OEM lock nuts included Fully rebuildable design *For use with factory-style 10mm damper shafts. If you have factory-style mounts presently, you have 10mm damper shafts. *During installation a 17ft-lb torque spec is required to avoid damage to the mounts.

Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.

ECS RSM features:

Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
80A polyurethane isolation bushings for NVH control
Accommodates 10mm, 12mm, or 14mm damper shafts
Fully constrained shaft mount makes RSM blow out impossible
Hard anodized 6061-T6 construction
Fully rebuildable design

* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.

This package is a complete overhaul of the rear suspension bushings in the E46 3-series. If your car is not feeling as crisp, has irregular tire wear, or has inconsistent (and unsafe) handling it's likely the rear bushings. We put together this package as a total overhaul to restore your car back to its original feel. Depending on the symptoms and diagnosis from your mechanic, it may be logical to replace all of the bushings in the rear suspension (there are 19 total). This is especially true if the subframe is being removed to repair or reinforce the rear floor (prone to failure).

Turner Motorsport is a big believer in using rubber bushings for street cars. Urethanes, Delrin, or aluminum are generally good for reducing compliance and limiting deflection - attributes that don't really work well on roads filled with potholes, railroad crossings, cracks, and expansion joints. The rubber bushings maintain the factory ride/handling traits that won the 3-series praise all over the world. Every bushing will need maintenance or replacement at some point and rubber has proven to last the longest and need less maintenance than anything else, even urethane. And unless competitive driving is your goal, the harder materials are only a gimmick.

Individual Item Descriptions:
Trailing Arm Bushings and Limiters (33 32 2 228 153 and TSU9990001) - our OEM rubber replacement trailing arm bushings (RTABs) are a perfect fit and help maintain rear toe alignment. The Limiters prevent premature bushing wear.
Rear Inner Control Arm Bushings (upper 33 32 1 092 247 and lower 33 32 6 770 824) - new stock inner rubber bushings for the upper spring arm and the lower camber arm. These do not wear out very quickly but should be replaced as a 'While you're in there...' job.
Rear Outer Control Arm Bushings (upper and lower) (33 32 6 775 551) - outer ball joints for the upper spring arm and the lower camber arm. These are the standard ball joint design found on the M3 and are a direct replacement upgrade on the other E46 models.
Rear Shock Mounts (JTD909) - Our very best JT Designs rear shock mounts with gaskets and hardware. If your mounts have not been replaced in the last 40,000 miles, now is the perfect time. Skip this option if you recently replaced mounts or already have an upgraded mount.
Rear Shock Mount Reinforcements (TSU9975100) - Even if your shock mounts are new or recent, the sheetmetal of the rear shock tower can still fatigue, leaving you with a very dangerous and expensive fix. These reinforcements are extra-thick, providing crucial strength to one of the weakest points on the car. They work with nearly every shock mount.
Differential mounts (33 17 1 093 175MY and 33 17 6 751 808MY) - Now is a great time to replace the rubber-isolated differential mounts. The diff mounts take the bulk of the twisting and binding as power is transmitted through the differential. We use a Meyle HD rubber bushing for the rear mount as it's stronger than the factory part.
Rear subframe mounts (33 31 6 770 783, 33 31 6 770 784, and 33 31 6 770 781 x 2) - The heart of the rear suspension, the subframe (or carrier) mounts located the entire rear suspension to the car. There are four mounts in total and bolt up into the rear floor. Worn subframe mounts are one of the leading contributors to rear floor-subframe failure. As the mounts flex, so does the sheetmetal of the chassis, which will fatigue the sheetmetal and crack the spot welds. Therefore, replacement of the subframe mounts is critical and a must when doing the subframe reinforcement or repair.

This mount package contains all of the commonly replaced rubber mounts and pads for the front and rear shocks on a 1999-2005 E46 3-series (not for M3 or xi AWD). While you're installing new front struts and rear shocks these are easily installed - there's no additional labor and special tools are not required. Since these pieces are mostly rubber, they dry up and crack over time. Re-using them lead to problems with fitment or noise, and may have safety issues as well. These mounts and pads are the perfect complement to your new shocks to help restore your car's handling and performance.

Pick and choose from mounts below:

Front strut mounts (also known as the guide support)

Front strut reinforcement plates (to prevent cracking and deforming of the front strut towers)

Front and rear self-locking mounting nuts

Rear Lifetime Warranty 'Repair Shop' shock mounts

Rear shock mount reinforcements (to prevent cracking of shock towers)

Rear shock mount gaskets The spring pads, dust boots, and bump stops can be added from the menu below. Note that front bump stops and dust boots are generally not required if you're using Bilstein struts, Bilstein coil overs, H&R coil overs, or KW coil overs. Those struts come with their own front bump stops and boots and may include rear stops and boots as well.

We offer three varieties of the rear shock mounts - OEM, Repair Shop, and HP alum-rubber. We recommend either the Repair Shop or HP mounts because the stock OEM design has a flaw that can lead to premature failure of the mounts. The Repair Shop and HP mounts use a different design that will last longer and the Repair Shop mounts also have a lifetime warranty!

This item fits the following BMWs:
