ReadyLIFT 5-6" MAX2.1 Suspension System for 2011-2019 GM Silverado and Sierra 2500HD/3500HD

The 42-31540 is a 5" to 6" MAX2.1 suspension system for 2011-2019 Chevy Silverado and GMC Sierra 2500HD and 3500HD trucks. It includes what you need to clear larger wheels and tires and puts Falcon 2.1 monotube dampers on all four corners. Browse more lift kits.

Laser-cut, fabricated heavy-duty steel crossmembers and cast iron OE-style knuckles carry the geometry. Torsion bar relocation brackets avoid the traditional lowering of the torsion bars, which helps ground clearance. Forged torsion keys, differential drop brackets and CV axle spacers are part of the kit. See GMC Sierra parts for more.

Why it works
Falcon 2.1 dampersVehicle-specific monotube shocks on all four corners improve roll control and low-speed damping.
Better clearanceTorsion bar relocation brackets skip the traditional torsion bar lowering.
Rock-ready shaftsShafts are 3/4" induction hardened chrome plated to resist rock damage, corrosion and buckling.
Tire fitA 5-6" lift allows up to 35x12.50 on a 20x9 wheel with 0 offset.
Fitment

2011-2019 Chevy Silverado and GMC Sierra 2500HD/3500HD. Some single rear wheel models may need custom U-bolts for the factory tow package, and the kit will not fit dual rear wheel trucks without them. Towing capacity will be reduced. ReadyLIFT designs it to be driven in 2WD at speed on public roads, with 4WD for off-road or slow adverse conditions.

ReadyLIFT 5-6" MAX 2.1 Suspension System FAQs

Does it fit dually trucks?

Not without custom U-bolts. Some SRW trucks with the factory tow package may also need custom U-bolts.

Will it affect towing?

Yes. Towing capacity will be reduced with the kit installed.

Can I drive it in 4WD on the highway?

ReadyLIFT designed it to be driven in 2WD at speed on public roads. Use 4WD off-road or in slow, adverse conditions, because high-speed driveline vibration can occur.

Do I need a different driveshaft?

A double cardan driveshaft may be required to help eliminate high-speed 4WD front driveline vibrations on 5-8" kits.
