What It Helps Address
- Front-end sag from worn original struts and springs
- Loose or inconsistent ride control over bumps and pavement transitions
- Reduced stability during braking, cornering, or towing-related load changes
- Noise and harshness caused by aging suspension components
- Time-consuming assembly work when replacing separate strut parts
Installation Notes and Tips
RS551784 is a front suspension strut and coil spring assembly with gas-charged construction and a 3.81-inch travel length. Its compressed length is 13.91 inches, extended length is 17.72 inches, and body length is 11.29 inches. Verify front suspension configuration and match the vehicle application before installation. Because this is a complete assembly, it can reduce the need to transfer individual spring and strut components during service.
