Rogue Engineering just like all their products, spend countless hours on research and development, designing these rear trailing arm bushings (RTAB) to out perform any other bushings on the market.  Rogue did not just stop there with design but took it further to create a new material that has the capabilities of both a smooth squeakless ride as well as having the ability to take anything a track junky can dish out.

If your have any questions about these Rogue Engineering Rear Trailing Arm Bushings please give us a call at 714-582-3330

Rogue Engineering RTAB's Fits the following vehicles:

  • All E36, including M3.  Does NOT fit Z3 and 318ti.
  • All E46, including M3.
Professional Installation Required
  • Because the RTAB "console" removal is required, an alignment is recommended.  For installation of the part itself, it is very straightforward, but requires some special tools

Because of the unique design, installation of the bushings is much easier than factory bushings.

Problems with Factory Mounts
The factory BMW RTABs (Rear Trailing Arm Bushings) are a very soft material to provide the quietest, most comfortable ride possible.  Because of this, Rogue Engineering has seen factory mounts require replacement in less than 50,000 miles and 3 years.  On modified vehicles, expect them to require replacement sooner.

Are your bushings already shot?
A simple test to determine if the stock rear trailing arm bushings require replacement is driving the vehicle in a straight line.  While in gear, under full acceleration, does the car pull to one side?  Additionally, under full, firm application of the brakes, does the car pull again?  If you answered yes to either one, the bushings probably require replacement.  Factory bushing from a 3 year old, 25,000 mile vehicle.

Rogue Engineering Performance RTABs
The bushing material used in Rogue Engineering Performance RTABs are now available in two different compounds, specifically for your needs.  Both compounds now incorporate a silicone impregnated, polyurethane compound.  The biggest different being the hardness of the material.

BLACK This compound is formulated for STREET applications.  Softer than Rogue Engineering blue, TRACK compound, these are stiffer than stock factory OEM bushings and designed to last much longer than stock.  Since these are the great compromise between OEM and Rogue Engineering TRACK bushing.  Engineered to approximately Shore A 93 hardness.
BLUE This harder compound is designed for TRACK applications, where monoball components are not allowed.  Less expensive than full Delrin bushings, these bushings are extremely stiff to provide the absolute maximum performance at the TRACK.  Purposefully engineered to approximately Shore D 65 hardness.

This hardness is important in this bushing especially in modified vehicles, since they will exert more force on the rear suspension during acceleration.

The inner sleeve that supports the bushings is made from 6061-T6 aluminum, CNC'd to exacting specifications for a perfect fit, here in the good 'ole USA.

Do NOT confuse these bushings with bushings produced outside of the US, with unknown material with questionable hardness.  Rogue Engineering has installed similar bushings produced by other companies which are simply too soft.  In these cases, it would have been better if stock bushings were used since it allows too much movement of the rear trailing arm.

Tired of the Squeaking?
Rogue Engineering's manufacturer has offered Rogue Engineering a silicon based formula, to also keep the urethane bushings quiet during use.  Approximately 1.3 oz. of silicon is poured into the mold, which means that it is permanently impregnated into each bushing.  This process costs more to produce, but Rogue Engineering feels that it makes for a better product in the long run.

A common downside of the urethane bushings over stock rubber ones was that they would typically develop noise over time (or even right away).  These noises were from a combination of the harder material, inadequate lubrication (or none at all), and the contact with the factory steel mounting hat rubbing against the bushing.  

A new, exclusive feature now incorporated into the Rogue Engineering RTABs is Rogue Engineering new machined "grease trap".  You can see this "grease trap" (picture 1), which is the small area around the end of the aluminum pin.  This allows for lubricant to be remain captive during the installation of the bushings (picture 2) instead of being scraped off by the factory steel mounting hat.  Rogue Engineering is the only company on the market to introduce a novel solution such as this to reduce the noise without sacrificing the performance.
