For the rear of the Colorado, we chose Bilstein 5165 Universal Fit shocks. Their remote reservoir dramatically increases shock oil capacity for good heat dissipation and damping sensitivity. Special swivel banjo fittings on the reservoir hose allow for 360 degrees of rotation. For increased wheel travel and more shaft movement, the “floating” dividing piston is located in the reservoir. Space was tight up front, so we chose Bilstein 5125 Universal Fit shocks. The 5125s feature self-adjusting deflecting disc valving, independent rebound and compression tuning, and their high-flow piston reduces harshness. Both shocks are sold by length and valving and require additional hardware when used in the Colorado’s OE mounting points. The OE bushings and sleeves can be pressed out of the stock shocks and reused, but we had Bilstein send new hardware.
