Description

The ReadyLIFT 6" Big Lift Kit, designed for 2019-2023 Chevy Silverado and GMC Sierra 1500 4WD trucks, is a comprehensive upgrade excluding Trail Boss, AT4/AT4X models. This kit, model 44-3965, enhances ride quality and handling through advanced engineering. It includes boxed steel front/rear cross members and a 3/16" thick steel front skid plate. The kit also features 1/4" steel differential drop brackets with double gusset and boxed center rib for torsional strength. Strut extensions are angled and offset, aligning struts for optimal shock performance and minimal wear, complemented by a lower mount strut pre-load spacer for spring rate improvement. For rear elevation, 5" tall fabricated steel blocks with bump stop landings are paired with Bilstein 5100 series shocks. Engineered over 9 months with extensive testing, this kit provides superior ride quality, even surpassing the stock setup. It supports maximum tire sizes of 35x12.50 on 20x9 wheels with 0 offset without trimming, and with trimming, accommodates 35x12.50 or 325/60R20 on 20x10 wheels with -18 offset. Trimming involves the front valance, felt liner edges, and mud flap. Not suitable for Auto 4 Hi, Adaptive Ride Control, Multimatic vehicles, or rear composite mono-leaf springs. Compatible only with traditional steel leaf springs, identified by square U-bolts. Key features include maintained factory ride and handling, clearance for up to 35'' tires on 6-inch kits with no trimming, top mount strut extensions preserving factory geometry, and the inclusion of a ReadyGuard Powertrain Warranty.

Fast, friendly service! Eric was a pleasure to work with in taking care of an insurance claim for my damaged truck bed topper for my 2007 Ford F150. The new topper was delivered and installed the very next day! It looks great...a lot better than the one I had on there!!! I highly recommend Leer Truck Accessories of Conyers for all your truck accessory needs!

I understand now why LEER has such high reviews. Blake and Justin create an environment that is completely stress free. Their knowledge and communication skills are top notch. My trailer hitch install was complete in less than an hour. Make the call, you won't be disappointed!!

Wonderful people to work with. I have had both a Tono cover and mudflaps installed. They even helped finish up a taillight installation that I almost completed. These are the best people that I know to go get anything for your truck. I would recommend them highly!

Called the night before for a repair on the trailer. They were there at the exact time they said they would be and was very quick with the service. The technicians were very kind and polite, they even explained some parts and how they worked. Will definitely be back if i have any issues in the future when in the area.

I recommend for anyone needing upgrades to their vehicle. I was in and out in an hour for my lightning installation. I'll be back.
