Product Details
Bilstein B8 5100 shocks are tuned for specific vehicle applications, and this rear shock is built for Ram 2500 fitments that require added suspension travel. The monotube construction helps maintain consistent response, while the digressive piston reacts to road inputs for controlled ride quality and handling. This part number, 24-302043, is listed for 2020-2025 Ram 2500 rear applications without air leveling suspension, as well as 2019 Ram 2500 rear applications with 0-1 inch rear lift. This part cross-references Rancho RS77044 for the same application.
Common Issues This Shock Can Address
- Excessive rear bounce on lifted Ram 2500 trucks
- Reduced control over rough pavement and washboard roads
- Rear-end instability during towing or hauling
- Worn factory shock performance on higher-mileage suspension systems
- Inconsistent damping after repeated heat buildup
Installation Notes
Compatible With 2020-2025 Ram 2500, rear, without air leveling suspension, and 2019 Ram 2500, rear, with 0-1 inch rear lift. Verify collapsed and extended length before installation to confirm suspension travel and lift height. Use the correct upper stem and lower eye mounting points for the vehicle application. Part number 24-302043 is a rear shock absorber only.
Quality Assurance
Bilstein B8 5100 shocks are engineered as application-specific replacements for lifted trucks and SUVs, with tuning matched to the listed fitment. The zinc-plated finish, monotube design, and included bellows boot support long-term suspension service in demanding use.
