QUICK OVERVIEW


ReadyLIFT delivers a performance game changer for the popular 2011-2019 Chevy Silverado and GMC Sierra 2500/3500 HD trucks with the release of our new 5"-6" MAX2.1 Suspension 2.1 Falcon shocks. Designed to improve stance, performance, and capability, this kit includes everything necessary to clear larger wheels and tires. With vehicle-specific performance-tuned Falcon 2.1 dampers on all four corners of our 5"-6" kits, these lift kits provide a better-than-factory feel.  Falcon Performance Shocks improve performance and comfort regardless of the terrain. The versatility of these systems makes them ideal for daily driving, off-road excursions, and tow/haul duties.

 

The 42-31540 5"-6" MAX2.1 system includes laser-cut, fabricated heavy-duty steel cross-members, new cast iron OE-style knuckles with the perfect geometry built-in, torsion arm brackets, taller cast style rear lift blocks, new forged torsion keys with the proper amount of indexing. These new torsion bar relocation brackets eliminate the traditional lowering of the torsion bars, which can inhibit ground clearance and help to improve the overall driving experience. Additionally, each kit includes crucial differential drop brackets and CV axle spacers, sway bar end links, bump stop extensions, OE style cast rear lift blocks, heavy-duty steel skid plate, and finally, Falcon shocks. 

 

 

Features:

- Vehicle-specific performance-tuned Falcon 2.1 monotube dampers on all four corners.

- Improved dynamic roll control and low-speed damping.

- Dramatic improvement in on-road comfort and off-road performance.

- Optimized fitment for unobstructed suspension travel and articulation.

- 6061-T6 aluminum alloy shock body resists Impact to protect internal components.

- Smooth-honed internal shock body surface for long-term performance.

- 3/4" induction hardened chrome plated shaft resists rock damage, corrosion, and shaft buckling.

- Large shaft diameter provides a wide range of adjustments on adjustable shocks.

- Hard anodized 6061-T6 aluminum alloy billet piston.

- 1-piece Teflon bronze piston wear band w/ O-ring.

- Heavy-duty fabricated steel components utilizing 3/16″ and 1/4″ steel plate

- Full-coverage differential skid plate constructed from 3/16″ steel plate

- Laser cut, CNC formed heavy-duty front/rear drop crossmembers.

- 5"-6" lift allows up to 35x12.50 with a 20?-9" with 0 offset 

 

NOTE: Some SRW (Single Rear Wheel) models may require custom U-Bolts to accommodate the factory tow package. Will not fit DRW (Dual Rear Wheel) applications without custom U-bolts. Towing Capacity will be reduced with the installation of this kit. This kit is primarily designed to only be driven in 2WD at speed on public roads and that 4WD is only to be used off-road or in adverse slow speed conditions due to drive line vibrations at high speeds. A double cardan driveshaft may be required to help eliminate some of the high-speed 4WD front driveline vibrations when kits are 5-8'' high.

 

TIRE FITMENT

35" Maximum tire diameter

35x12.50 for no rub on a 9" wide wheel with -6 offset

18" - 35X12.5R18

20" - 35X12.5R20

Tire Size Note: ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer. Every tire and wheel combination should be test fit prior to installation. Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note: When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.

Feels Like Sleeping on a Cloud
Color: Black, Size: Queen
This mattress topper completely transformed my bed. From the first night, I noticed how much softer and more comfortable my mattress felt. The pillow-top design adds a plush layer of cushioning without making the bed feel overly soft or unsupportive. I was especially impressed by how breathable it is. I tend to get warm while sleeping, but this topper stays comfortable throughout the night and doesn’t trap heat. The moisture-wicking fabric is a nice bonus and helps keep the bed feeling fresh. The deep-pocket design fit my mattress perfectly and stayed securely in place without shifting around. Installation was quick and easy, and the black color gives it a sleek, premium look. After fluffing up, it provided just the right amount of extra comfort and made my mattress feel much more luxurious. For the price, this topper offers excellent value and has greatly improved my sleep quality. I would definitely purchase it again and recommend it to anyone looking to add softness and comfort to their bed.

Feels Like Sleeping on a Cloud — One of My Favorite Bedsure Products Yet
Color: Black, Size: King
I’ve had really good experiences with Bedsure products over time, so whenever I get the chance to try another one I usually do, and this mattress topper definitely did not disappoint. This one went on my mom’s king size bed and the difference was noticeable immediately. The topper has a soft, cloud-like feel while still giving enough support underneath so you don’t just sink straight through it. It added a much more comfortable layer to the mattress and made the bed feel cozy and inviting without being overly heavy or hot. I also appreciated how easy it was to put on. The deep pocket design fit securely over the king mattress without struggling to stretch the corners, and once it was on, it stayed in place well through the night. The material feels breathable and smooth, which is especially nice for warmer nights. My mom commented that she slept really well with it and woke up feeling more comfortable than usual, which honestly says a lot. Overall this feels like a high-quality mattress topper that makes a bed instantly more comfortable. Bedsure continues to be one of those brands I trust for soft bedding and reliable quality.

Not Worth the Price
Color: Black, Size: Queen
I expected more. The images are a bit misleading with the amount of fluff and thickness the product actually has. Despite following the instructions, it’s pretty flat. It had a funky chemically smell to it, so I sprayed with some Febreeze. Honestly in my opinion I don’t think it’s worth $60. I think if you want something similar, go to Marshals or TJ Maxx.

Makes my camp mattress so much better.
Color: Black, Size: Full
I'm in a small motorhome and this has helped my sleep quality a ton. I got rid of my big mattress because the 2 camp mattresses I have are smaller in size, but a bit dense than the mattress I had. Uncomfortable for anyone that sleeps on them for long periods and when I come from biking or hiking the pain was making it hard to sleep. These have improved my sleep quality immensely. It also, to my surprise fit well, the cushions are only a few inches. These are up to 18, but the edge is nearly a perfect fit at the start. The straps keep it from moving. The length and width using 2 of the bed rolls is nearly perfect. On mattress the deeper part of the pocket, would fit perfectly. The quality feels great, lightweight and washable, this is one of those items I wouldn't have likely ordered, but trying it is near priceless for my usage. Couldn't imagine how good it must be on a bed.

The material feels cool to the touch, lightweight, and breathable, so you stay comfortable without feeling heavy or sweaty. It also features moisture-wicking and quick-dry properties, which help keep the bed fresh throughout the night.

It’s also machine washable and durable, maintaining its cooling performance even after multiple washes, which makes it practical for long-term use.
