Top Turner Suspension & Camber Products | E36 3 Series

Our sealed Monoball Rear Trailing Arm Bushings (RTAB) are the best solution for completely eliminating deflection and unwanted toe changes on the rear of the E36, E46, and Z4. While rubber and urethane bushings flex during load, the toe can change widely giving you nervous and unpredictable handling. These RTABs have a solid aluminum housing with a high-quality sealed OE bearing. These bushings were developed from years of competition use in various racing and HPDE events. There is simply no better RTAB unless your racing class rules prohibit the use of mono or spherical bearings.

The rear trailing arm bushings take a lot of abuse from acclerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car. We also offer a Delrin RTAB for cars that must conform to certain racing class rules. These sealed spherical bearings are the best at controlling rear toe alignment.

Our aluminum RTABs are very well made - high grade aluminum alloy and steel CNC'd out of a billet by an ISO 9001 certified manufacturer, each component is either hardcoated or nickel plated. While multiple manufacturers offer two piece designs, our research showed that a one piece bushing is a better design featuring a sealed bearing to keep contaminants out extending the life of the bearing.

If you're installing a rear shock on your E30/E36/E46/Z3/Z4 that utilizes a Spherical Bearing or Rod-End, commonly referred to as an "eye mount", and used with racing shocks/dampers, this is the upper rear mounts needed to attach your shock to the chassis. The mount is machined out of aircraft grade aluminum with a high quality coating and premium hardware. Note: 2 Bushing kits are included for common eyelet bearings; see chart for sizes. If you do not see the bushing kit you need, give us a call and have our in-house machine shop build you custom bushings.

Our Racing Rear Lower Shock Mount is machined out of aircraft grade aluminum. We include both the TSU9007B15 and TSU9007B50 bushing kits with this package.

These adjustable rear links are only required when using sway bar / swaybars with a suspension with a very low ride height, where it may be necessary to adjust the length of the end links for proper sway bar clearance from the drive axles or other suspension components. These suspensions are usually found only on race cars but this may also apply to street cars with sport springs/sport coil overs that are lowered a lot. On most street cars lowered 1.5" or less, the stock links will be fine.

These end links feature a Heim joint, which allows enough lateral movement when disconnected to adjust the length of the link without removing the entire link from the car. This is particularly helpful when eliminating or adjusting preload while tuning the suspension. Similar links without this joint, can't be adjusted without totally removing the link from the car.

Built-in grease fittings allow for occasional lube, and a packet of grease is included. These links are sold as a set, and include two end links and hardware for H&R and TMS sway bars (other brands may not need the hardware). 

At their shortest setting they are 2.875" hole to hole and on their longest setting they are 3.5" hole to hole.

*Note: these links will not work with factory or non-adjustable Eibach sway bars.
