SACHS 993 371 Coil Spring – Front Axle

Uneven ride height, a harsh or bouncy ride, and knocking noises over rough pavement are classic signs a coil spring has reached the end of its service life. The SACHS 993 371 coil spring is a replacement part engineered for the front axle, restoring the ride height and load support your suspension needs for a level stance, controlled handling, and a smoother ride on U.S. roads from coast to coast.

Key Benefits

The SACHS 993 371 coil spring is manufactured to match OE load-bearing and ride-height specifications. Here’s what makes this replacement part:

• Correct ride height restoration engineered to SACHS 993 371’s manufacturing tolerances so your vehicle sits level and handles predictably.
• 352 engineered to match OE load rating and mounting geometry for a direct-fit installation.
• Consistent load support under braking, cornering, and towing, reducing bottoming-out over rough pavement.
• Improved tire contact and wear patterns by keeping ride height and alignment geometry within spec.
• Corrosion-resistant coating designed to withstand road salt, moisture, and temperature swings across all 50 states.
• SACHS manufacturing standards, backed by a standard parts warranty against defects in material and workmanship.

Product Specifications

Every SACHS 993 371 coil spring is manufactured to tight dimensional and load-rating tolerances. Full technical details are listed below; always verify fitment against your vehicle’s VIN before ordering.

SACHS, a ZF brand, has manufactured suspension components for over a century and is a trusted OE supplier to numerous automakers.

Use Cases and Applications

This front coil spring is suited for routine suspension maintenance, pre-inspection replacement, and restoring ride height after a spring sags or breaks. Typical scenarios where drivers choose this part include:

• Replacing a sagged or fractured coil spring identified during a routine service visit or alignment check.
• Restoring even ride height after one spring weakens while the opposite side is still within spec.
• Preparing a vehicle for towing season or long-distance travel where consistent load support matters most.
• Addressing a harsh or clunky ride, uneven ride height, or uneven tire wear traced back to worn springs.

Because it’s engineered for front axle applications, this part is intended to be installed as a direct axle-position match — not interchanged with the opposite end of the vehicle.

Frequently Asked Questions

What vehicles is this coil spring compatible with?

This SACHS 993 371 coil spring is manufactured to fit the front axle of its specified applications. Always cross-reference your vehicle’s VIN or OE part number against our fitment guide, or contact our support team through the contact page before ordering to confirm compatibility.

Is this a direct OE replacement?

Yes. The SACHS 993 371 is engineered to match the load rating, free length, and mounting geometry of the original equipment coil spring, so no additional modification is required for installation.

Should I replace coil springs in pairs?

Most suspension technicians and OE manufacturers recommend replacing coil springs on the same axle in pairs to maintain even ride height, handling balance, and tire wear on both sides of the vehicle.

Should I replace the shock absorber at the same time as the coil spring?

Yes, this is strongly recommended. A coil spring and shock absorber work together to control ride height and damping; replacing only one often leaves the other component working outside its designed range. Browse our shock absorber catalog for a matching axle-position replacement.

What is spring rate and why does it matter?

Spring rate is how much force is required to compress the spring a given distance, and it directly determines ride height, load capacity, and ride comfort. This part is manufactured to match the OE spring rate for its listed application.

How long does shipping take?

Orders ship nationwide to all 50 U.S. states. Standard delivery typically takes 3–7 business days depending on your location; expedited options are available at checkout. Full details are on our shipping policy page.

What is your return policy on this part?

Unused parts in original packaging can be returned within our standard return window. Review the complete terms on our warranty policy page or reach out via our contact page.

Does this coil spring come with a warranty?

Yes, this part is covered by the manufacturer’s standard warranty against defects in material and workmanship. Warranty terms are outlined on our warranty policy page.

How much does professional installation typically cost?

Labor costs vary by shop and region, but coil spring replacement requires a spring compressor and is best performed by a licensed repair shop, typically completed in under an hour per axle. We recommend having alignment checked after installation.

Can I install this coil spring myself?

Experienced DIY mechanics with a proper spring compressor can often complete this installation at home, but coil springs store significant compressed energy and improper handling can cause serious injury. If you are unsure, we recommend having it installed by a certified technician.

Why is this part priced at $43.99?

Pricing reflects the SACHS brand’s manufacturing quality, materials, and engineering tier relative to other options in our catalog, while remaining competitive with comparable OE and aftermarket parts.

Do you ship to my state?

Yes, we ship to all 50 U.S. states with tracked, insured shipping on every order.
