Common Issues This Part Can Address

• Sagging front ride height from worn coil springs
• Uneven stance after years of heavy-duty use
• Reduced front suspension support on loaded vans and trucks
• Loss of ride consistency caused by fatigued springs
• Front-end settling on classic GM C/K, G-series, and R-series vehicles

Installation Notes and Tips

Verify the vehicle’s brake code, suspension package, drivetrain configuration, and rear-wheel setup before ordering, since fitment varies by application. This spring set is for front position use only. Because coil springs store significant energy, professional installation and proper spring-compression tools are recommended.

Quality Assurance

MOOG is known for ongoing chassis design improvements that focus on longer service life and easier replacement. Part number 6454 is built to meet the dimensional and application requirements listed above for direct suspension service on confirmed GM fitments.
