Eibach Coilover Spring and Shock Assembly

Eibach Coilover Spring and Shock Assemblies: Engineering Meets the Road and Trail

When it comes to combining a precision spring with a high-performance shock absorber into a single, cohesive unit, few names carry the credibility of Eibach. Eibach engineers, manufactures, and sells the highest quality performance aftermarket suspension products in the world, and their coilover spring and shock assemblies represent the pinnacle of that commitment — integrating decades of motorsport know-how into systems that work equally well on paved mountain roads and rugged off-road trails.

The Pro-Truck Coilover Lineup

Eibach's flagship coilover assembly offering for trucks and SUVs is the PRO-TRUCK Coilover system, available in tiered Stage configurations to match different use cases and budgets. The front features the PRO-TRUCK Coilover 2.0, offering precise adjustability and control, while the rear is equipped with PRO-TRUCK Reservoir dampers for unmatched stability and comfort in any condition. The Stage 2 and Stage 2R systems are engineered for drivers who demand genuine off-road capability without giving up everyday driveability.

What sets these assemblies apart at a hardware level is the quality of their construction. Featuring anodized 6061-T6 billet aluminum coilover mounts, a high-performance 46mm piston, and nitrogen-filled variable force valving, these assemblies provide unmatched precision and durability. The monotube damper architecture ensures consistent thermal performance even under sustained hard use — a direct inheritance from Eibach's deep motorsport roots.

ERO Off-Road Race Springs: The Heart of the Assembly

Every Eibach coilover assembly is built around one of the brand's most celebrated components: its race-grade coilover springs. ERS Coilover Springs are produced to motorsport-grade tolerances, retaining consistent rate and static height, and are available in a wide range of lengths, rates, and diameters. The assemblies are ERO Off-Road Race Spring equipped and compatible, which means owners can swap spring rates to fine-tune ride behavior for different loads or terrain types without replacing the entire shock.

Eibach also backs up its engineering with rigorous quality control. Each assembly is individually dyno tested for matched performance and reliability — a step that ensures the left and right sides of your vehicle respond identically, a critical factor for handling balance and predictability.

Adjustability and Ride Height Customization

A defining feature of Eibach coilover assemblies is their adjustability. A front adjustable threaded spring perch accommodates increased loads and maximum clearance, giving truck and SUV owners the flexibility to dial in their desired lift height and load capacity. Whether you are leveling a half-ton pickup, preparing a midsize truck for overlanding, or building a dedicated trail rig, Eibach's coilover systems offer a tunable platform rather than a one-size-fits-all solution.

Made in the USA, Backed by Eibach's Legacy

All Eibach products are meticulously tested for reliability and manufactured in the U.S.A., at their Corona, California facility. Eibach offers a 1,000,000-mile warranty on their PRO-TRUCK SHOCK products, underscoring the brand's confidence in the durability of these assemblies. For any driver serious about extracting the most from their truck or SUV's suspension, Eibach coilover spring and shock assemblies represent a thoroughly engineered, race-proven upgrade.
