FITMENT: The DR2500CA suspension enhancement system fits 2002-2008 Dodge Ram 1500, 2003-2010 Dodge Ram 2500, and 2011-2013 RAM 2500 TOWING SAFETY: Say goodbye to difficult handling, rear sag, and dangerous corner sway while towing or hauling. Timbren SES kits feature Aeon rubber springs that progressively adjust to heavier loads, giving you a smoother, safer ride whether you're hauling an RV across the country or a trailer full of hay. Rated for up to 6,000 lbs, you can tow with confidence knowing your ride is stable and controlled. ENCHANCED RIDE: With Timbren SES kits, you'll experience a smooth and controlled ride even when your vehicle is fully loaded, thanks to the innovative Aeon rubber springs that eliminate squat, sway, and roll. Unloaded? No worries! A gap between the spring and frame ensures a comfortable drive, giving you the best of both worlds for everyday and heavy-duty use. EASY INSTALLATION: Unlike air bag systems, Timbren SES kits require no post-installation maintenance and can be installed in under 30 minutes—right from your driveway! No special tools, no hassle. You’ll be ready to hit the road quickly with enhanced towing capacity and peace of mind. INCLUDES: Comes with 2 patented Aeon SES suspension hollow rubber springs, 2 steel mounting brackets, 2 1” rubber spacers, and all necessary hardware
