The kits were sold as an accessory for model year 2005-2021 Ford F250 4X4 and F350 4X4 pickup trucks.
The foam ring inside the stabilizer "through shaft" may block the piston ports, possibly causing the steering to lock up.
If the steering locks, it can increase the risk of a crash.
What to do
Icon will notify owners, and dealers will install a new shock assembly with a revised foam ring and steel support disc into the steering stabilizer free of charge.
The recall was expected to begin in December 2020.
Owners may contact Icon customer service at (951) 689-4266.
