Product Details
Rancho RS7MT is the brand’s performance-focused strut line, engineered for drivers who split time between pavement and trail. The RS77846 uses a monotube telescopic design with a 46 mm bore size, 5.55 inches of travel, 16.18 inches compressed length, and 21.73 inches extended length. Its front application supports 2019-2025 Chevrolet Silverado 1500, 2019-2024 GMC Sierra 1500, 2022 Chevrolet Silverado 1500 LTD, and 2022 GMC Sierra 1500 Limited. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What It Helps Address
- Excessive front-end bounce after bumps or dips
- Reduced control with heavier wheel and tire packages
- Heat buildup during demanding off-road driving
- Suspension response that feels loose or inconsistent
- Dirt intrusion around the strut shaft and seal area
