MQB Rear Lower Control Arm Inner Bushings – FK Bearings – Core Exchange

The rear lower control arm bushing works with trailing arm to hold the rear alignment, and transfer cornering forces to the tires. Like the trailing arm bushing, it is extremely flexible under load, causing alignment to vary under acceleration, braking, and cornering and resulting in a lag between driver inputs and vehicle response. The spherical upgrade increases the precision and responsiveness 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 rear lower control arm inner 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 Rear Lower Control Arm upgrade is designed to be pressed into the factory rear 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 $225 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.
