JXB Performance MQB Trailing Arm Bushings - Aurora Bearings - No Control Arms - MQB03A0-AU
The rear trailing arm bushing is the weakest point of the rear suspension.
It is extremely flexible under load, causing alignment to vary wildly under
acceleration, braking, and cornering. The spherical upgrade increases the
precision and feel of the rear end:
Inspires more confidence in corners
Delivers better road feel and feedback
Holds alignment under load
Does not bind
Eliminates random oscillations to increase grip
2 spherical trailing arm bushings with motorsport-grade PTFE-lined
spherical bearings
FK WSSX10T bearings are standard, optional upgrade to Aurora PWB-10T
bearings
Both options feature a stainless steel ball and race and bonded PTFE liner
The JXB Spherical Trailing Arm Bushing upgrade is designed to be pressed
into the factory trailing arms. Typically this is done with an H-frame
hydraulic press. Don’t want to deal with it? We’ll press them in for you.
We’ll send you a pair of factory arms completely assembled with our
bushings. Just install them and send us back your original arms for a $150
core refund. Just select the core exchange option.
Note: JXB reserves the right to refuse at its sole discretion any returned
core that is not in sellable condition. Conditions that may affect
acceptance of core returns include but are limited to excessive surface
rust or pitting, mechanical defects (scrapes, dents, stripped holes, etc),
and integral ball joints with excessive wear. If you are unsure of the
condition of your cores, please send detailed pictures before returning
them.

Rubber bushings act like little springs at each suspension pivot point.
They allow suspension geometry to change under load, ruining your alignment
and causing unwanted handling characteristics like steering wander,
binding, camber, caster, and toe changes, and lack of steering and
suspension feedback. Spherical bearings do not bind or flex under load,
creating perfect suspension joints.
We use only the highest quality motorsport-grade PTFE-lined bearings for
best performance and lifespan. We use high strength 7075 aluminum for the
bolt sleeves, and 6061 for the bearing cups. Bearings are interference-fit
into the cups, so they won’t creak or rattle. Both internal and external
retaining rings ensure everything will always stay in place.
Please note that lifespan will vary based on the application and driving
conditions. Spherical bearings do have moving parts, so they do wear. Our
bearing kits are fully rebuildable. Please contact us for rebuild kits.
