JXB MQB Spherical Front Lower Control Arm Bushing Upgrade
The front lower control arm bushings are responsible for maintaining the alignment of the front end under all driving conditions. The factory bushings are soft and flexible, causing unwanted toe-in and camber loss during braking and turning. The spherical upgrade increases the precision, responsiveness, and feel of the front end:
Inspires more confidence in corners
Delivers better road feel and steering feedback
Holds alignment under load
Does not bind
Eliminates random oscillations to increase grip
The JXB Front Lower Control Arm Upgrade is the only kit to replace both factory bushing locations with precision motorsport grade PTFE-lined spherical bearings for a no compromise front end solution.
Caster-Correcting Option
Choose the caster-correcting option to receive our offset rear bushings, which increase caster by approximately 1°. The increase in caster increases much-needed front end grip by increasing negative camber on the outside wheel and decreasing negative camber on the inside wheel during cornering (basically leaning the wheels into the turn). Please note that the the caster correction does push the wheel slightly forward in the wheel well which may cause tire clearance issues on aggressively stanced or lowered cars.
What’s Included
2 spherical front lower control arm bushing kits with motorsport-grade PTFE-lined spherical bearings
FK WSSX10T bearings are standard, optional upgrade to Aurora bearings
Both options feature a stainless steel ball and race and bonded PTFE liner
Core Exchange Program
The JXB Spherical Front Lower Control Arm upgrade is designed to be pressed into the factory front lower control 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 $200 core refund. Just select the core exchange option.

Why Spherical?
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.
Construction
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.
