Improved Ride Quality & Performance by Rancho

After lifting or leveling your 2011-2025 GM 6.6L Duramax truck, chances are you won't have the ride quality you once knew and loved caused by the new stresses on your suspension system. If you want to win back the ride performance on your rig then you'll need a set of high-quality shock absorbers from Rancho! While sold individually, a pair of these premium Front Shock Absorbers will help soften any impacts when you're out on the trail while stiffening up your control over uneven terrain and during any tough applications like towing or hauling. This gives you and your passengers a smoother off-road ride without compromising for the comfort of everyday street drives. Better yet, these shocks were designed with a 9-position adjustable tuner that allows you to fine tune the suspension performance of your ride in every situation.

Premium Construction & Installation Info

Rancho designed this shock absorber with the avid adventurer in mind as it was built around a massive 70mm tri-tube body that has more fluid capacity over stock to be ready for just about anything you have in mind. Moreover, the gas pressurized design of this shock minimizes the air-to-oil mixture which helps promote consistent performance over any terrain. The hardcore construction of this unit results in structural integrity, resistance to dirt and debris, and added durability for the most extreme environments so you can take on your next adventure head-on. When it comes to installation, this shock can be mounted directly in place of your existing components for a fast and easy process you can complete at home. Rancho backs this shock with a Limited Lifetime Warranty to help keep your investment protected!
