Canada’s Timbren Industries recently introduced a new Timbren SES upgrade that fits the rear suspension of a Chevrolet Silverado 1500 Trail Boss. This new kit – part number GMRS15 – mounts to the frame using existing holes. Timbren’s zero maintenance upgrade prevents sag, reduces sway and enhances ride quality under load without compromising unloaded ride quality, the company said. Every Timbren SES upgrade comes with a lifetime warranty and a customer satisfaction Guarantee.
