H&R Coilover Springs

H&R coilover springs are sold individually by inner diameter, free length, and spring rate, so you can build a coilover setup from scratch or re-rate one you already own. They're cold-wound in Germany from the same high-tensile steel that made H&R's reputation.

Choosing the Right Coilover Spring

Three numbers decide whether a coilover spring will work for you. The inner diameter, or ID, has to match your coilover's perch and collar, and it's the first thing to get right because a mismatched ID simply won't seat. Free length determines how much travel and preload you have to work with, and the spring rate sets how stiff the car feels and how much load it takes to compress. H&R offers a broad range of IDs, lengths, and rates so you can match all three to your specific coilover.

If you're not certain what your coilovers take, measure the ID of your existing spring and note its free length before ordering, or send us your coilover brand and model and we'll confirm what fits.

Why H&R Race Springs Hold Up

H&R race springs are cold-wound from high-tensile chromium-silicon steel in Germany, the same construction behind their lowering springs. That's why they hold their rate over years of use instead of sagging, which matters even more on a coilover where a settled spring throws off your corner heights and your whole setup. They use a linear rate, so the stiffness stays consistent through the travel and the car behaves predictably as you load it up.

When to Change Your Spring Rates

Re-rating is one of the most effective ways to transform a coilover setup you already own. Going stiffer sharpens body control for track use and helps a car on slicks or semi-slicks, while going softer can restore compliance and mechanical grip on rough surfaces or a street car that rides too harshly. Rate changes are also how you fine-tune balance, and how you dial in corner weights on a track car.

FAQs

What are coilover springs?

They're the individual springs that sit on a coilover, sold separately by inner diameter, free length, and spring rate. You buy them to build a coilover setup from scratch or to re-rate one you already own.

How do I know what ID coilover spring I need?

The inner diameter has to match your coilover's perch and collar, so measure the ID of your current spring or check your coilover manufacturer's spec. A mismatched ID won't seat properly. Send us your coilover brand and model and we'll confirm.

Are H&R coilover springs linear or progressive?

H&R race springs use a linear rate, meaning the stiffness stays consistent through the travel. That predictability is what you want on a coilover setup where you're tuning balance and corner weights.

Will H&R springs fit my brand of coilovers?

They'll fit any coilover whose perch matches the spring's inner diameter and whose travel suits the free length. H&R offers a wide range of IDs and lengths, so most common coilover setups are covered. Contact us with your setup if you're unsure.

Do H&R coilover springs sag over time?

They're built not to. Cold-wound from high-tensile chromium-silicon steel in Germany, they hold their rate over years of use, which is important on a coilover where a settled spring throws off your ride height and corner weights.

How do I choose a spring rate?

It depends on the car's weight, your damper valving, and how you drive. Stiffer rates suit track use and grippier tires; softer rates restore compliance on rough roads. Tell us your car, coilovers, and use and we'll help you pick.
