The strongest, easiest way to level out your Chevrolet or GMC Heavy Duty. These ReadyLIFT torsion keys are designed to grab the "FLAT" of the torsion bar for a tighter, sturdier fit. CNC machined adjuster bolt pockets and 10.9 grade metric hardware allow for proper bolt seating, ensuring an accurate and safe adjustment. Only ReadyLIFT torsion keys are forged, making them 25% stronger than OEM and primed to last the life of your vehicle.The adjustable torsion key provides 2" to 3" of lift and gives clearance to add up to 33" tires to your GM HD. ReadyLIFT keys are guaranteed never to affect the OEM ride and will not add more pressure on the stock suspension components.
ReadyLIFT kits cost thousands less than a traditional lift kit and install in about 1-2 hours.
For those who install heavy front items such as snow plows, the ReadyLIFT torsion keys will allow you to adjust your suspension to compensate for the extra weight, as well as give you the opportunity to not only increase the lift amount, but adjust it to suit while maintaining your factory ride.
ReadyLIFT Lifetime Warranty Included! All ReadyLIFT products are backed by a lifetime warranty for as long as you own your vehicle and includes all necessary parts, hardware, detailed installation instructions, and two color decals.
IMPORTANT NOTES:
- 66-3050 - Custom torsion key adjusting bolts are included that prevent the installer from over-cranking the torsion key, which affects ride. The kit may be dialed up with the stock adjusting bolts, but which may also affect ride quality. 2008-2010 year HD trucks will need to use the factory bolt to achieve the desired 2.5" of lift.
- 66-3050 - A heavy duty shock extension bracket replaces the OEM bracket to keep the correct piston travel on the already short stock shock.

Good value for the money.
Size: 9.5 Wide, Color: Beige
Comfortable right out of the box. Great style and well made. The more you wear the softer they get but maintain their overall appearance.

Comfortable fit for slip-in fabric shoes
Size: 14, Color: Black/Black
My first experience with Marc Joseph. I typically purchase dress and casual work shoes from Florsheim and occasionally Rockport. I'm giving these four stars because the initial fit and feel appear solid. Depending on the shoe brand I wear a size 14 or 15. My feet are slightly wide but I don't alway need wide fit. These size 14 fit well with wide enough toe box. I've tried slip in shoes before and they just don't feel right. These somehow work and there is no heel slip. My only reservation is the high lip on the heel for slip-in and hope they dont catch pant hems. I gave 4 stars because I'll have to determine durability. Granted they are a light fabric shoe with a soft rubber tread. I'd like them to last for at least 6 months..and use them for business casual work wear during warm weather.
