Eibach

Eibach builds performance springs and suspension — over 350 parts across lowering and lift springs, Pro-Kits, sway bars, coilovers and alignment hardware.

Springs are the brand's core, and the ranges are named for intent. Pro-Kit lowers modestly to cut body roll and improve appearance while keeping factory dampers viable. Sportline drops further for a more aggressive stance. On the truck and 4x4 side, Pro-Lift-Kit springs raise the front for tire clearance using a real spring rather than a spacer, which preserves suspension travel.

Spring rate and damper have to suit each other. Lowering springs on tired factory shocks will float and bounce, so plan the damper alongside the spring rather than after it — and expect an alignment afterwards, since ride height change moves camber and toe.

Most listings here carry verified vehicle fitment, so you can filter to your own year, make and model rather than guessing from a part number.
