Timbren Industries recently introduced a Timbren SES upgrade for the rear 
suspension of the  00- 21 Toyota Tundra &  16- 21 Toyota Tacoma. This new 
severe service kit mounts to the leaf spring using existing U-bolts. This new 
Timbren SES kit is designed to eliminate side-to-side sway and roll, and give 
additional suspension support for vehicles with slide-in campers. It's
also ideal for wreckers, dump bodies and any vehicle with a high centre of
gravity due to top heavy loads.
