Eibach 10in C/O Spring Platinum 2.50in ID

Eibach XT Barrel Main Spring – 10.00 in Length | 2.50 in Diameter | 500 lbs/in Rate

The Eibach XT (Extreme Travel) Barrel Main Spring is designed for racers and builders who demand the perfect balance between suspension travel, spring rate precision, and durability. Purpose-built for coilover applications, this 10.00-inch spring features a barrel-shaped coil design that provides exceptional travel while minimizing block height — a critical advantage in tight coilover or stacked spring configurations.

Manufactured from Eibach’s proprietary ultra-high tensile spring steel, the XT Barrel Series delivers industry-leading strength-to-weight performance. Each spring is individually tested for exact rate accuracy, giving tuners and fabricators predictable, repeatable suspension behavior under even the harshest off-road or track conditions.

Engineered for Extreme Travel and Consistency

Eibach’s XT Barrel design enables greater usable stroke before coil bind, maximizing performance and suspension articulation. The linear rate profile maintains predictable handling through the full range of motion, ensuring consistent compression and rebound behavior. Lightweight yet strong, the XT Barrel Spring is perfect for performance coilover systems in UTVs, desert race vehicles, and custom suspension builds that demand control and responsiveness at every inch of travel.

Key Features

• 500 lbs/in spring rate — ideal for front or rear high-load coilover applications.

• Barrel-shaped coil design provides more usable travel and eliminates coil bind.

• Ultra-high tensile steel construction for superior strength and reduced unsprung mass.

• Linear rate design ensures consistent compression response and improved damping control.

• Compact block height (3.76 in) allows for extended travel in tight coilover assemblies.

• Individually tested and labeled to ensure precision and reliability.

• Corrosion-resistant finish for long-term durability under extreme conditions.

• Made in the U.S.A. by Eibach — the global leader in performance suspension components.
