The added weight of a travel trailer will cause the rear of your tow vehicle to squat. If the rear end sits too low, your steering will be compromised. Additionally, your sagging rear end will cause instability and porpoising. Here’s the bad news: when these conditions exist, you’re looking at unsafe driving conditions. Here’s the good news! An easy-to-install SES kit will maximize safety for you and your family by keeping the rear end of your tow vehicle level and stable. Avoid any travel safety hazards by installing a Timbren SES kit on the rear suspension of your truck or SUV.
