Description
The 44-39420 lift kit utilizes the very best in ReadyLIFT engineering with boxed steel front/rear cross members and full-width front skid plate constructed of thick 3/16" plate steel. New 1/4-inch boxed plate steel differential drop brackets feature a double gusset and boxed center rib to take the abuse of front differential torsional twisting. Our 4" lift kit features heavy-duty angled and offset top mount strut extensions that realigns the struts to optimize shock performance and minimize wear. A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better handle the larger wheels and tires that will find their way onto this new lifted truck. To lift the rear, new fabricated steel rear blocks with integrated bump stop landings have been added as well as new rear shock extensions. With months of engineering and development and more awesome features than we could possibly mention, the bottom line is this new Big Lift Kit is the best 4" lift kit you can install on a new body style 2019-2023 GM 1500 4WD truck! Thousands of miles of road and trail testing have proven our new 4" lift kit makes these new GM 1500 trucks ride better than stock!

⭐️⭐️⭐️⭐️⭐️ 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. 💪

Lucas the sales guy did a nice job walking me and my wife thru the process he kept his word by keeping us up to date on the building process….Justin and the crew did a great job installing our building on 9-17-2026 building looks even better then in the 3d image website they where professional and respectful the only thing I hated for them was they played music while they were assembling my garage and my neighbors called corporate on them and corporate instructed them to turn it down we how ever didn’t mind the music at all so if your reading this Justin we appreciate your help we love the garage thanks -the McIntyres

Trevor and his team did an outstanding job delivering my new 10' by 16' aluminum shed to a very tight delivery location. The shed is outstanding and I was glad I went with Thrifty Portable Building. I highly recommend them if you are looking for a portable building.

I had a problem with a tonneau cover almost blowing off. I patched it as best I could and visited H & H in Muscle Shoals to see if they could fix it even though it had been installed at a different H & H store. Rusty was kind enough to fix it easily. Highly recommend this individual.

Ordered a half cover for the bed of my F-250. The cover arrived the next morning. Appointment to install so I could watch it being completed, so I can remove later. The young man that sold me the cover as well as installed the cover was absolutely great. He explained everything patiently with excellent communication skills and instruction. This was a very pleasant experience THANKS!
