Overview

The Rancho RS7MT RS77023 is a rear suspension shock absorber tuned for on-road control and off-road handling. It is built for Chevrolet Colorado and GMC Canyon applications that call for a monotube shock with heat dissipation and debris protection.

Fits 2015-2022 Chevrolet Colorado, rear and 2015-2022 GMC Canyon, rear. The RS77023 part number is used across these rear shock applications, including RS7MT-specific fitments.

Key Features

  • Monotube shock design for efficient heat dissipation during demanding use.
  • Integrated dirt wiper sealing system helps keep dirt and debris out.
  • Hardened piston rod resists scuffs and corrosion.
  • Internal rebound bumper smooths suspension movement over changing terrain.
  • Loop bushing and sleeve upper and lower mounts for direct shock replacement.
  • Extended bumper stop included in the design.

Detailed Description

Rancho RS7MT shocks are engineered for drivers who want controlled damping in mixed street and trail conditions. This rear shock absorber uses a monotube construction with a 2-inch reserve tube diameter and 7.56 inches of travel, helping manage heat and maintain consistent performance under load. The RS77023 also uses matching upper and lower LS47 loop bushing and sleeve mounts, making it a fit-focused replacement for the rear suspension on Chevrolet Colorado and GMC Canyon models listed below.

The RS7MT product line is positioned for precision handling with the durability needed for larger wheel and tire packages and frequent off-road use. The integrated sealing system, hardened rod, and rebound bumper work together to protect the shock and maintain smoother suspension response on rough surfaces. This part cross-references Monroe Shocks & Struts (e.g., 23224315, 23224316) for the same application.

What It Helps Address

  • Excessive bounce or unsettled rear suspension response.
  • Heat buildup during sustained off-road driving.
  • Dirt intrusion that can shorten shock life.
  • Scuffing and corrosion on the piston rod.
  • Harsh rebound over uneven pavement or trail surfaces.

Installation Notes and Tips

Verify rear fitment by model year before ordering. This shock uses loop bushing and sleeve mounts at both ends, so confirm the LS47 mounting style matches the vehicle application. For best results, inspect related suspension components for wear before installation.

Quality Assurance

Rancho RS7MT shocks are built as application-tuned suspension components for demanding use. The monotube design, sealing system, and hardened rod construction support consistent performance in rear shock applications for Chevrolet Colorado and GMC Canyon.
