Monoball Suspension Bearings

For Porsche 991

Performance - Monoballs replace rubber bushings with spherical bearings that hold precise camber and toe, making the car predictable and easier to drive fast.

Sticky tires generate corner loads that compress rubber bushings. Camber and toe wander, requiring constant driver correction to compensate.

Weather Seals - Our proprietary-design Monoball cartridges have weather seals to keep dirt out and extend product life.

Dirt and water contaminate ordinary products and accelerate wear.

Lower Control Arm (Front) Eccentric Monoballs

For Porsche 991

Our Eccentric Control Arm Monoball Cartridges replace inner rubber bushings with spherical bearings, providing low friction and precisely holding camber settings. The eccentric design allows increasing or decreasing camber, as needed.

Made from hardened steel, plated and weather-sealed, these bearings are made to last.

 Lower Control Arm (Front) Eccentric For Porsche 991
Lower Control Arm Eccentric Monoballs For Porsche 991

Increasing camber - Position the eccentric to maximize Lower Wishbone length, adding .25 inches length and about .39 degree of negative camber. Cost effective for cars that just want extra camber. For even more camber and ease of adjustment, see our fully adjustable control arms.

Shown with factory wishbone, not included

Decreasing camber - Position the eccentric to minimize Lower Wishbone length. Perfect for lowered cars that have too much negative camber and want to get back to factory camber settings to minimize tire wear on the street.

Lower Wishbone (Rear) Eccentric Monoballs

For Porsche 991

Our Eccentric Lower Wishbone Monoball Cartridges replace inner rubber bushings with spherical bearings, providing low friction and precisely holding camber settings. The eccentric design allows increasing or decreasing rear camber, as needed.

Lower Control Arm (Rear) Concentric Monoballs

For Porsche 991

Monoball Cartridges replace factory rubber bushings with hardened-steel spherical bearings. Spherical bearings allow free motion on multiple axis and eliminate deflection associated with rubber, resulting in more precise holding of toe and camber.

High tolerance machined housing allow for simple press fit installation. Correct spacers ensure proper fitment.

The kit includes 4 monoball bearings. two for each lower control arm. Order one kit per car.

Wheel Carrier (Rear) Concentric Monoballs

For Porsche 991

Monoball Cartridges replace factory rear wheel carrier bushings with hardened-steel spherical bearings. Spherical bearings allow free motion on multiple axis and eliminate deflection associated with rubber, resulting in more precise holding of toe and camber.

High tolerance machined housing allow for simple press fit installation. Correct spacers ensure proper fitment.

The kit includes 2 monoball bearings. One for each rear wheel carrier. Order one kit per car.

Upper Control Arms (Rear) Concentric Monoballs

For Porsche 991

Monoball Cartridges replace factory rear upper control arm bushings with hardened-steel spherical bearings. Spherical bearings allow free motion on multiple axis and eliminate deflection associated with rubber, resulting in more precise holding of toe and camber.

High tolerance machined housing allow for simple press fit installation. Correct spacers ensure proper fitment.

The kit includes 8 monoball bearings. 2 per arm, for 4 arms total. Order one kit per car.

Track Rod (Rear) Eccentric Monoballs

For Porsche 991

This monoball cartridge kit replace the inner and outer track rod bushings. The inner Eccentric bearings provide increased range of toe adjustment. This is to compensate for increased camber or lowered car that cannot be brought into toe range. The outer concentric bearing replaces the rubber bushing and eliminates deflection due to rubber compression.

Eccentric bearings are made from hardened steel, plated and weather-sealed to keep road contaminates out. These bearings are made to last.

For Porsche 991

Monoball Cartridges replace factory rear track rod bushings with hardened-steel spherical bearings. Spherical bearings allow free motion on multiple axis and eliminate deflection associated with rubber, resulting in more precise holding of toe and camber.

High tolerance machined housing allow for simple press fit installation. Correct spacers ensure proper fitment.

The kit includes 4 monoball bearings. 2 bearings per arm, for both track rods. Order one kit per car.

Rear Shock Lower Mount Monoball Kit

For Porsche 991

Monoball Cartridges replace factory rear shock Lower mount bushings with hardened-steel spherical bearings. The factory rubber acts as a spring in series with the shock. This rubber spring-action is completely un-damped and reduces the shock ability to control the tire contact patch. The spherical bearing allows the damper to do its job and control the contact patch.

High tolerance machined housing allow for simple press fit installation.

The kit includes 2 monoball bearings. 1 per side and inserts into the rear upright. Order one kit per car.

Front Lower Control Arms Center bushings

Rear Lower Control Arm – 991 control lower control arm bushings are fitted into the rear subframe. This tool allows for bushing extraction and installation without the need of subframe removal.

Rear lower control arm

Rear Lower Shock Mount – Similar to the control arm bushings, lower shock mount bushings are pressed into the lower shock mounts, this tool makes installation of these bushings easy and without removal of the subframe.
