On Christmas Day 1978, he established himself firmly in the singles ranks of the promotion by defeating Bruiser Brody for the NWA American Heavyweight Championship.

As the 1980s dawned, Kevin became one of the WCCW's most viable performers and continued to win numerous championships in both singles and tag team competition with a variety of different partners.

In early 1982, the Fabulous Freebirds, consisting of Michael Hayes, Terry Gordy, and Buddy Roberts, left GCW after meeting WCCW booker Gary Hart at a show.

Appearing in WCCW, the trio instantly became fan favorites due to a combination of their unique talents and chemistry as well as their close friendship with the Von Erichs.

During WCCW's annual Christmas show in 1982, Kerry Von Erich faced Ric Flair for the NWA World Heavyweight Championship inside of a steel cage with Michael Hayes acting as a special referee.

As explained in The Triumph and Tragedy of World Class Championship Wrestling DVD, the storyline, developed by Gary Hart, was written as Hayes having been selected by fans to be a special enforcer type of referee in the match.

The Freebirds immediately became the top heels in the company, due to the belief of many fans that their actions cost one of their local heroes the NWA World Heavyweight Championship.

Throughout the next several years, the Freebirds and Von Erichs engaged in numerous high-profile matches that were very physical in nature with the various members of each group feuding over various championships within the promotion.

This line of drama ended, when Kevin's brother, David von Erich, died in Japan from acute enteritis of the upper intestine.

Kevin also had a long feud with Chris Adams that lasted for months and had many violent matches, including two well-known chair shots on each other that required hospitalization for both men.

Kevin did manage to draw crowds to the Sportatorium in the early going, but with the absence of his brother, manager/booker Gary Hart, and the lack of televised matches, WCCW's survival was very thin.

On April 2, 1993, he teamed up with Chris Adams to defeat Fabulous Freebirds' Michael Hayes and Buddy Roberts at Global Wrestling Federation's Adkisson Benefit Show at the Sportatorium.

Kevin's last round of glory occurred on January 7, 1995, while competing for Jim Crockett, Jr.'s NWA promotion based at the Sportatorium where he won the North American Heavyweight Title, defeating Greg Valentine.

In 2006, Kevin and a number of others from WCCW's heyday participated in Heroes of World Class Wrestling, an independently produced retrospective documentary about the promotion and the Von Erich family.

On June 15, 2014, at Total Nonstop Action Wrestling's (TNA) Slammiversary XII, Kevin accompanied his sons Marshall and Ross to the ring for a tag team match.

He teamed with his sons Marshall and Ross as they defeated Marty Jannetty, Jumping Lee, and Gery Roif at The Rage Wrestling Mega Show in Tel Aviv, Israel.

Kevin also dabbles in commercial real estate and owns the rights to Southwest Sports (the distributor of World Class Championship Wrestling), now known as K.R.
