THE TECH
It All Starts with the Bushings
The patented Duroflex™ Joint (metalcloakpatents.com) combines ride comfort with the articulation needed for a flexible bolt-on suspension system.
MetalCloak combines the features of widely used control arm joints in a low-maintenance, self-centering, rebuildable design with 34° of misalignment and an OEM-quality ride.
Reinforced with Kevlar®
DuPont™ Kevlar® fiber is compounded into MetalCloak's proprietary Duroflex™ elastomer for added strength and durability.
Duroflex™ Bushings containing Kevlar® can be identified by the MetalCloak “M” on the outer surface.
Duroflex™ Joint Features
Vibration Damping & Self-Centering
The proprietary elastomer compound absorbs vibration and allows the joint to return to center, helping provide:
- Comfortable Ride Quality
- Suspension Articulation Without Binding
- Reduced Wear from Small Suspension Movements
High Misalignment
The Duroflex™ Joint allows substantial angular movement for suspension articulation.
- Over 34° of Misalignment per Joint
- Over 68° per Control Arm
Absorbs Micro-Movements
The Duroflex™ Bushing absorbs small rotational movements during daily driving, helping improve ride quality and reduce joint wear.
True Bearing Surface
The outer surface of the Duroflex™ Bushing acts as a bearing, allowing rotation when needed for articulation without binding the control arms.
Low Maintenance & Rebuildable
Duroflex™ Joints are designed for straightforward servicing. Remove the bushing, clean and inspect the components, apply fresh Teflon-impregnated synthetic silicone grease, and reassemble. Replace worn components as needed.
Forged for Strength
Forged threaded ends provide strength for demanding off-road use while allowing control arm length adjustment. Precision locking nuts secure the adjustment.
Shoehorn Washers
The included 1/8" steel dual shoehorn washers help guide the Toyota rear upper control arm joints into their mounting brackets. MetalCloak's signature gold zinc finish helps protect the washers against corrosion.
