ReadyLift 44-3070 - Full-Size Lift Kits

Description

The ReadyLIFT 7" to 8" Adjustable Lift Kit System is designed for 2011-2019 Chevy Silverado / GMC Sierra 2500HD/3500HD 2WD/4WD trucks and comes complete with four SST3000 Performance Shocks tailored for this kit. This premium system is engineered to provide a 7"-8" adjustable front lift and a 5.0" rear lift, ensuring both off-road strength and on-road ride quality. The kit, designated as 44-3070, also includes tubular Upper Control Arms and features precision-cut sub-frame assemblies that directly bolt in, along with custom nodular iron knuckles for ideal geometry, ride, and handling performance. To maintain proper CV axle angles on 4WD applications, an integrated differential drop bracket system is included. The front lift is achieved using ReadyLIFT Forged Torsion keys, offering adjustability while preserving the factory ride. For the rear, an OEM-quality cast iron 5.0" tall rear block is provided without compromising ride comfort. Additional components encompass steel bump stop extensions, a skid plate, and sway bar end links. This kit is compatible with stock 20" wheels or 9" wheels with 4.75" - 5.5" backspacing, but it can't be used with stock 17" or 18" wheels. The subframe and other components are coated with a durable Plascoat finish, renowned for its resistance to stress cracking, abrasion, impact, and various environmental factors. It's designed to protect against adverse weather conditions, detergents, salt spray, and airborne pollutants. Please note that SRW (Single Rear Wheel) models may require custom U-Bolts for accommodating the factory tow package. This kit may reduce towing capacity. It's important to note that this kit is primarily intended for 2WD use at speed on public roads, and 4WD should be reserved for off-road or slow-speed conditions due to potential driveline vibrations at high speeds. In some cases, a double cardan driveshaft may be necessary to mitigate high-speed 4WD front driveline vibrations in kits ranging from 5" to 8" in height.

⭐️⭐️⭐️⭐️⭐️ WOW – That’s How You Stand Behind Your Work H&H installed my airbags last year, and recently I ran into an issue where they stopped working. From the very first call, they were incredibly helpful and patient, walking me through troubleshooting over the phone trying to save me a trip. When we couldn’t get it resolved, I called first thing Monday morning and they had me scheduled right away. They got the truck in, diagnosed the issue, and replaced the parts — completely under warranty — no hassle, no excuses. A couple hours later I was back on the road. That’s rare service these days. Professional. Honest. Stand-up guys who truly stand behind their work. H&H is hands down the place to go for all your truck needs. 💪
