Timbren SES Suspension Enhancement System, FRTT1504E Rear Severe Service Kit

Hauling top-heavy loads like truck campers or salt spreaders requires more stability than other towing or hauling solutions. This is when you need the Timbren SES Severe Service Kit. What’s the difference between the Severe Service Kit and the classic Timbren SES kit? Both products feature the progressive spring rate of Aeon rubbers springs. As load increases, these rubber springs push back harder, eliminating squat, sway, and roll.The Timbren SES Severe Service Kit uses a single-convoluted Aeon spring. Designed exclusively for truck campers, these springs resist weight more aggressively to keep your vehicle level and your ride smooth. The result? No more white-knuckling it down the highway; you get a safe, stable handling of your top-heavy load. After installation, there should be a 1/2″ to 1-1/2″ gap between the rubber spring and vehicle’s frame – meaning you’ll enjoy a comfortable unloaded ride.What makes the Timbren SES Kit different from other suspension enhancement systems? Unlike air bags, this kit requires zero post-installation maintenance. Unlike foam, this kit is durable enough to last under all your loads, in any weather. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.• Made exclusively for top-heavy applications that require maximum stability, like truck campers• Reduces sag, sway, and roll when towing and hauling top-heavy loads• Comfortable unloaded ride• DIY installation• Zero post-installation maintenanceSpecsRated Capacity: 7000 lbs.Kit Height without 1″ Spacer: 5.75″Kit Height with 1″ Spacer: 6.75″NOTE: Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating).
