Review SUPERLIFT For Rear Replacement Component Box for RAM 3500 2013–2018

Introducing the Superlift 4685 Series Rear Suspension System for the 2013-2018 Ram 3500, an exceptional upgrade for your heavy-duty pickup truck. This system is designed to enhance your off-road capabilities, improve ride quality, and add an impressive stance to your vehicle.

The core component of this system is a pair of 4600 series heavy-duty fabricated rear shocks. These shocks feature a 2.5-inch diameter body, 16.5 inches of travel, and a high-pressure nitrogen charge for consistent performance. The external reservoirs increase the shock's oil capacity, ensuring excellent heat dissipation and consistent damping during prolonged off-road excursions. The remote reservoirs also provide easy access for maintenance and adjustments.

The 4685 Series Rear Suspension System also includes a pair of 3-inch diameter, 12-leaf springs. These heavy-duty springs offer improved load capacity and better control over the vehicle's weight distribution, ensuring a more stable and confident ride. The springs are also designed with a progressive rate, which provides excellent ride quality both on and off the road.

The system also includes Superlift's heavy-duty, bracket-style rear sway bar links. These links help to reduce body roll during cornering and improve handling, making your Ram 3500 more agile and responsive. The links are precision-engineered for a perfect fit and are constructed from durable materials for long-lasting performance.

Additionally, the 4685 Series Rear Suspension System includes all necessary hardware for installation, including new u-bolts and shackles. This system is designed to be a direct replacement for your stock suspension, making the installation process straightforward and hassle-free.

In summary, the Superlift 4685 Series Rear Suspension System for the 2013-2018 Ram 3500 is an excellent choice for those seeking improved off-road capabilities, better ride quality, and a more aggressive stance for their heavy-duty pickup truck. With its heavy-duty fabricated shocks, progressive-rate springs, and durable sway bar links, this system is designed to provide reliable, consistent performance, no matter where the road takes you.
