Show original supplier description
The Kenny Brown K-Link AGS 4.5 Rear Grip Suspension System, protected by US Patent #11505027, is an advanced rear suspension module designed to deliver superior grip and handling. It offers the lateral locating advantages of a Watts Link while providing even more grip than a Panhard Bar, resulting in enhanced performance on both the street and the track. This system achieves quicker turn-in, solid mid-corner stability, and increased forward bite, which translates to faster corner exit speeds and improved lap times. It includes the K-Link Zero-Roll Axle Control Module, AGS 4.0 Rear Lower Control Arms, AGS 4.0 Anti-Squat Axle Brackets, and the AGS 4.0 U-Link Upper Control Arm Module. A complimentary 15-minute consultation with a Kenny Brown Performance Specialist is included to help optimize your setup. It's important to note that the K-Link system generates significant rear grip, necessitating a substantial increase in rear spring rate to maintain car balance for optimal performance. For 2005-2010 Mustangs, an upgraded FORD Upper Control Arm Upper Bolt, part #FOR-W714389S439, is required. Kenny Brown Performance recommends scheduling a consultation to ensure correct spring and shock selection for your S197 Mustang.
