Suspension Parts at Coilovers.com

Beyond complete coilover kits, Coilovers.com carries a full catalog of suspension parts — sway bars, end links, control arms, bushings, mounts, springs, and the components that complete a serious suspension build. Across our 11-brand lineup, the parts side of the catalog supports everything from a single sway bar upgrade to a complete chassis-control rebuild.

Call us at 1-800-460-9106 if you want to talk through which parts complete your build.

What's in the Suspension Parts Catalog

Whiteline Performance covers the deepest portion of our parts catalog. Whiteline's Australian rally and motorsport heritage translates into one of the most comprehensive aftermarket lineups for sway bars (front, rear, adjustable, fixed-rate), sway bar links and end links, sway bar bushings, control arms, control arm bushings, alignment bushings, lateral links, panhard rods, differential mounts, and chassis-stiffening components. If you're building a serious driving car on a supported chassis, Whiteline's parts catalog is where most of the supporting modifications come from.

Öhlins Racing contributes coilover service parts and motorsport-spec components — replacement springs, top mounts, valving components, and the supporting service items that keep an Öhlins kit on the road over multi-year ownership. Öhlins parts are the difference between a coilover that lasts five years and one that lasts ten with a midpoint rebuild.

Swift Springs supplies the upgrade-spring portion of the catalog. Swift Springs are Japanese motorsport-grade replacement springs that drop into supported coilover kits from BC Racing, Fortune Auto, and other brands — delivering tighter rate tolerance and faster recovery than the standard linear springs most kits ship with.

The smaller parts items — top mounts, camber plates, replacement bushings, lockout collars, helper springs, and similar consumable or service components — appear across the catalog from the same brands that build the coilovers themselves.

How Parts Choices Fit a Build

Sway bar upgrades change how the chassis behaves in transitions without changing ride height or damping. They're the single highest-impact suspension modification per dollar spent on most front-wheel-drive and AWD platforms — and they pair well with a coilover kit by handling roll stiffness independently from the spring rate.

Bushing upgrades change how the chassis transmits load through the suspension geometry. Stiffer bushings sharpen response at the cost of some ride compliance. Polyurethane or aluminum-bushing upgrades are common on track-focused builds; for daily-driven cars, OEM-rubber bushings often remain the right call.

Control arm and end-link upgrades correct geometry issues that show up when a chassis is lowered substantially. Lowered cars often have suboptimal control-arm angles and overly-short OEM end links — the geometry-correction parts fix this.

Spring upgrades (Swift Springs and similar) replace the standard springs in a coilover kit with motorsport-grade alternatives. The upgrade pays off on track-focused builds; for street-only builds, the standard springs in BC Racing, Fortune Auto, and KW kits are typically the right call.

Building a Complete Suspension System

The path most customers run: start with a coilover kit, then add the parts that match the use case as the build matures.

Street-focused build: Coilovers, possibly Swift Springs, possibly upgraded top mounts. That's usually the complete recipe.

Spirited driving / canyon build: Add a front sway bar upgrade, an end-link upgrade if the geometry needs it, and consider bushings if the chassis is lowered substantially. Whiteline and similar brands cover this.

Track-focused build: Coilovers, Swift Springs, both sway bars, end links, lateral links, control arms, comprehensive bushing replacement, top mounts, camber plates. The parts side of the build often costs as much as the coilover kit itself.

The right approach depends on what you're actually doing with the car. A five-minute phone call to figure out which parts genuinely matter for your build saves both money and frustration. We won't push parts you don't need.

Frequently Asked Questions

Will a sway bar upgrade alone make a noticeable difference?

Yes — especially on front-wheel-drive and AWD platforms. A rear sway bar upgrade alone can transform chassis behavior on understeer-prone cars. It's one of the highest-impact-per-dollar suspension upgrades you can make.

Do I need to upgrade bushings when I install coilovers?

Usually no — for a moderate ride-height drop on a daily-driven car, factory bushings work fine. Bushing upgrades become worthwhile on aggressive drops, track-focused builds, or older platforms where the factory bushings are themselves degraded.

Can I install sway bars and end links myself?

Most sway bar and end-link installs are owner-installable with basic tools, particularly on common platforms like Civic, WRX, and Mustang. Control arm and lateral link installs are more involved and benefit from a lift and a shop. Call us if you want guidance on what's realistic for your specific install.

Do parts ship the same way as coilover kits?

Yes. Free shipping on most parts orders within the United States and Canada. Some larger items (control arms, lateral links) may have additional handling.
