Coil Springs FAQs
What's the difference between linear and progressive coil springs?
Linear springs hold one rate through their travel for predictable, consistent behavior under load; progressive springs start soft for ride comfort and stiffen as they compress. Linear rates suit heavy, constant loads and performance predictability. Progressive rates suit trucks that are sometimes empty and sometimes loaded, giving comfort unladen and support when packed. Choose by whether your weight stays constant or varies.
Coil springs or coil spacers for a level or lift?
Choose coil springs when you're adding weight or want real load support; choose spacers when you only need height on an otherwise healthy spring. Springs raise ride height and increase capacity for armor and gear, while spacers lift cheaply but add no load rating. If your truck already sags under accessories, a spacer makes it worse — new springs are the answer.
Will stiffer coil springs ride harshly?
Only if they're overspecced for your actual load. A spring rate matched to your loaded weight rides well because the added gear compresses it into its designed range. Run that same firm spring empty and it rides stiff and skittish. This is why you buy for loaded weight, not maximum stiffness. Pair the spring with correctly valved shocks for the best result.
