Upgrade the rear suspension performance of your lifted 2011–2026 Chevrolet Silverado or GMC Sierra 2500 HD or 3500 HD with the ReadyLIFT Falcon 3.3 Fast Adjust Rear Shock Pair.
Designed for compatible ReadyLIFT 6" and 8" suspension systems, these premium rear shocks provide improved control, comfort, off-road stability, heat management, and damping consistency.
Falcon 3.3 Fast Adjust technology provides three primary compression settings and eight Micro Adjust levels, allowing suspension performance to be tuned for daily driving, towing, trail use, and changing vehicle loads.
The piggyback-reservoir design increases shock oil capacity and helps manage heat during demanding use, providing more consistent damping performance on the road and trail.
These shocks are compatible with rear lift-block heights ranging from 3" to 6". They are standalone rear replacement or upgrade shocks and do not provide lift by themselves.
This product includes the rear shock pair only. It is not a complete suspension lift kit and must be used with a compatible ReadyLIFT suspension system.

Fitment Notes
- These shocks are standalone rear replacement or upgrade components. They are not a complete lift kit and do not create suspension lift by themselves.
- The vehicle must already be equipped with a compatible ReadyLIFT suspension lift system.
- Compatible with rear lift-block heights ranging from 3" to 6".
- ReadyLIFT markets these shocks for 6" and 8" lift systems. The applicable rear lift height is determined by the existing lift system and rear block—not by the shocks alone.
- Confirm the vehicle’s existing lift-kit part number and rear block height before ordering.
- The current ReadyLIFT product page lists fitment for 2011–2026 GM 2500 HD and 3500 HD trucks. However, its linked installation instructions are titled “2020 GM HD 8" Falcon 3.3 Rear Shock Kit.” Applications outside the model year identified by the instructions should be verified against the vehicle’s existing ReadyLIFT lift system before ordering.
- ReadyLIFT does not provide separate 2WD and 4WD fitment details on this standalone shock listing. Confirm drivetrain compatibility through the vehicle’s existing ReadyLIFT base lift kit.
- The linked instructions reference a ReadyLIFT 42-30840 lift system developed using 37x12.50 tires on 20x10 wheels with a -18 offset. This wheel and tire information is an installation reference for that complete lift system and should not be presented as universal tire fitment for these standalone shocks.
- Wider tires may require different wheel offsets and vehicle trimming.
- Factory wheels may be used with the referenced lift system but are not recommended with tires wider than 11.5".
- The factory spare tire and wheel may be used for emergency purposes only. ReadyLIFT limits use to short distances at no more than 45 mph to help prevent differential damage.
- The factory spare wheel may not clear the front steering knuckle on certain lifted applications. If a front tire becomes flat, ReadyLIFT directs the driver to move a rear wheel to the front and install the factory spare on the rear.
- Suspension lift height may vary due to factory ride height, vehicle configuration, and payload options.
- Do not combine these shocks with incompatible suspension systems, body lifts, or other lifting devices.
- The vehicle must be in excellent operating condition before installation. Worn or damaged suspension, steering, driveline, or related components must be repaired before installing the shocks.
