TBN-DR1500DQ

Unstable loads while towing and hauling don’t just make for an uncomfortable ride. Difficult handling, rear sag, and corner sway create dangerous driving conditions — for you, your passengers, and other vehicles.

Whether you’re towing your RV across the country or hauling hay down the highway, Timbren's Timbren RAM 1500 SES kit provides a simple, effective solution to improve load stability and ride quality. Designed for 2009-present RAM 1500 crew cab and quad cab models, this suspension upgrade eliminates sag and enhances control for a smoother, safer ride.

How? Timbren's Aeon® rubber springs deliver a progressive spring rate. As load increases, Timbren's rubber springs push back harder, eliminating squat, sway, and roll. After installation, there should be a ½” to 1 ½” gap between the rubber spring and vehicle’s frame — meaning you’ll enjoy a comfortable unloaded ride, too.

What makes Timbren SES kits different from other RAM 1500 suspension enhancement systems? Unlike air bags, Timbren's kits require zero post-installation maintenance. And unlike other systems, you can install and haul in under 30 minutes, right from your driveway.

Features:

• Reduces sag, sway, and roll when towing and hauling
• Comfortable ride, loaded or unloaded
• DIY installation
• Zero post-installation maintenance

Specs:

• Rated Capacity: 8600 lbs
• Overall kit height = 5.5”

Fitment:

• 2009-2010 Dodge RAM 1500 2WD/4WD Crew Cab, Quad Cab
• 2011-2026 RAM 1500 2WD/4WD Crew Cab, Quad Cab
• 2019-2025 RAM 1500 Classic 2WD/4WD Crew Cab, Quad Cab

Notes:

• Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
• Does not fit the following RAM models with factory air ride suspension
• RAM 1500-All New (2019- Present)- Regular, Crew Cab & Quad Cab
• RAM 1500 Classic (2019- Present)- Regular, Crew Cab & Quad Cab
• RAM 1500 (2009-2018)- Regular, Crew Cab & Quad Cab

TBN-DRTT1500

Maybe you’ve been there: white knuckles gripping the steering wheel while your truck camper sways back and forth down the highway. Add in some cross-winds, and keeping your vehicle centered on the road just became the kind of drive that makes you second-guess your trip altogether.

Hauling top-heavy loads like truck campers or salt spreaders requires more stability than other towing or hauling solutions. This is when you need Timbren's Timbren SES severe service kits.

So what’s the difference between Timbren's severe service kits and classic Timbren SES kits?

Both products feature the progressive spring rate of Timbren's Aeon® rubbers springs. As load increases, Timbren's rubber springs push back harder, eliminating squat, sway, and roll.

But Timbren's Timbren SES severe service kits use 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 ½” to 1 ½” gap between the rubber spring and vehicle’s frame — meaning you’ll enjoy a comfortable unloaded ride.

What makes Timbren SES kits different from other suspension enhancement systems? Unlike air bags, Timbren's kits require zero post-installation maintenance. Unlike foam, these are 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.

Features:

• Made exclusively for top-heavy applications that require maximum stability, like truck campers or salt spreaders
• Reduces sag, sway, and roll when hauling top-heavy loads
• Comfortable unloaded ride
• DIY installation
• Zero post-installation maintenance

Specs:

• Rated Capacity: 7000 lbs
• Overall kit height = 5.75”

Fitment:

• 2009-2010 Dodge RAM 1500 2WD/4WD Crew Cab, Quad Cab, Regular Cab, 
• 2011-2026 RAM 1500

Notes:

• Even though you’re increasing the spring rate by adding this upgrade, this does not increase the GVWR (Gross Vehicle Weight Rating). Please make sure that the load does not exceed the GVWR set by the manufacturer.
• Does not fit the following RAM models with factory air ride suspension
• RAM 1500-All New (2019- Present)- Regular, Crew Cab & Quad Cab
