Eibach's Stage 2 Pro-Truck-Lift kit (part E86-23-042-03-22) replaces the front suspension with threaded-body Pro-Truck Coilover 2.0 units and adds rear sport shocks for the 2023-and-newer Chevrolet Colorado. The threaded-body 2.0" coilover system offers precise ride height adjustment and enhanced off-road performance. Out of the box, the coilover height is set to be level with OE rear height, so the front lift is dialed in from that baseline. The damper uses anodized 6061-T6 billet aluminum coilover mounts, a 46mm piston, and a monotube design with nitrogen-filled variable force valving, per the manufacturer's listings for earlier Colorado coilovers.
Compared with stock, this kit is about control as much as height. Owners describe the ride as firmer than stock with much less body roll. Owners on user forums also caution that the coilover rides excellently as long as you don't entirely max them out, so a moderate spring perch setting is the sweet spot. For harder off-road use, the Stage 2R version adds rear reservoir shocks for increased damping control and heat management. Before ordering, confirm fitment: the manufacturer lists this part for the WT, LT, and Z71 with the 2.7L four-cylinder in 4WD.
Installation is a suspension-level job, not a casual bolt-on, so budget time and a shop lift. Shoppers searching for 2023 Colorado Z71 front coilover lift, threaded coilover 2.7L Colorado 4WD, or Pro-Truck Coilover 2.0 Colorado are usually weighing an adjustable front against a fixed spacer, and the threaded body is the main reason to choose this kit. Plan on an alignment afterward, and check fender clearance if you run larger tires.
The manufacturer lists this part for the WT, LT, and Z71 with the 2.7L four-cylinder in 4WD. Fitment details vary across sources, so confirm with the manufacturer before ordering.
Both use the same threaded front coilovers. The manufacturer says the Stage 2R pairs them with rear reservoir shocks for more damping control and heat management, while the Stage 2 uses rear sport shocks.
Yes. The manufacturer's install sheets say to check wheel alignment, fender clearance with aftermarket wheels or tires, brake line clearance, and ABS sensor positioning after installation.
The manufacturer's Pro-Truck coilover install sheets state that only qualified mechanics experienced in the installation and removal of suspension components should perform this installation. A hoist and screw jack are recommended. Expect to need 10mm, 15mm, 17mm, and 18mm sockets or wrenches, a pry bar, hammers, and a pull strap or zip ties to hold the knuckle. Watch for a few gotchas: never use impact wrenches or impact guns to install or remove shock absorber piston components, shafts and piston rod nuts. All Eibach springs should be installed with the Eibach logo right-side-up. On the earlier Colorado coilover sheet, the knuckle is aluminum, so the arm may need to be shocked to drop. Set both coilovers to the same height before installation, as the manufacturer's sheets direct.
