Q: Why replace coil springs on a classic car?

Decades of compression cause springs to lose free length and spring rate. Replacing them restores correct ride height, handling, and load capacity.

Q: Should I replace springs in pairs?

Yes. Always replace front springs as a pair and rear springs as a pair, even if only one side is sagging, so the vehicle sits and handles symmetrically.

Q: Are there other names?

Suspension coil spring
Replacement coil spring
Front coil spring kit
Rear coil spring kit
Spiral suspension spring

Names vary by manufacturer.

Q: Do I need any special tools to install?

Yes. A spring compressor is required for safe installation, especially on front springs trapped between the upper and lower control arms. Always follow the proper service procedure for your vehicle.

Q: How does spring choice affect ride quality?

Standard-duty springs match factory ride. Heavy-duty springs raise spring rate to support added load (towing, cargo, larger engines) and produce a slightly firmer ride.
