PITTSBURGH, Jan. 13, 2026 /PRNewswire/ -- "I wanted to create a modified radius arm to adjust the suspension system within newer super duty trucks," said an inventor, from Lincoln, Calif., "so I invented the ROCK LOCK. My adjustable design enables you to add flexibility or stability with the flip of a switch when off-roading or during normal driving conditions."

The patent-pending invention provides an adjustable upper arm and 4 link radius system for newer super duty trucks. In doing so, it would replace the standard fixed upper radius arm. As a result, it offers added flexibility when off-roading. It also increases stability during normal on-road driving. The invention features a durable and adjustable design that is easy to control so it is ideal for the owners of certain super duty trucks from 2005 and newer.

The ROCK LOCK is currently available for licensing or sale to manufacturers or marketers. For more information, visit www.rocklock.net. Or contact Alex Jones at 916-765-0877 or email info@rocklock.net.
