Eibach XT Barrel Main Springs – 16.00 in Length | 2.50 in Diameter | 100–175 lbs/in Rates

The Eibach XT (Extreme Travel) Barrel Main Spring Series redefines what’s possible in coilover performance. Designed for long-travel coilover systems and professional off-road racing applications, these 16.00-inch springs deliver exceptional suspension travel, low weight, and linear rate precision for vehicles that demand control and compliance through extreme terrain.

Manufactured from Eibach’s proprietary ultra-high tensile spring steel, the XT Barrel Series combines lightweight performance with incredible strength and fatigue resistance. Available in 100, 125, 150, and 175 lbs/in spring rates, this lineup gives fabricators and suspension tuners the flexibility to fine-tune every inch of travel. From compliant UTV setups to heavy-duty pre-runner builds, these springs provide reliable, repeatable response in the harshest race environments.

Built for Maximum Suspension Travel

Engineered for coilover configurations where stroke and control matter most, the Eibach XT Barrel Spring’s hourglass-shaped coil design allows more deflection before reaching coil bind. This translates to greater usable travel, smoother compression, and consistent performance under high-load cycles. Combined with Eibach’s precision heat treatment and shot-peening process, these springs deliver a perfect balance of strength, weight, and durability — mile after mile.

Key Features

• Available in 100, 125, 150, and 175 lbs/in rates for wide suspension tuning capability.

• Barrel-shaped coil design increases travel and prevents coil bind in dual-spring or long-travel setups.

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

• Linear rate design for predictable response through compression and rebound.

• Smallest block heights in their class for maximum usable suspension stroke.

• Individually tested to ensure consistent rate accuracy and performance.

• Corrosion-resistant finish provides long-term durability and consistent rate retention.

• Made in the U.S.A. by Eibach — the trusted name in performance suspension.
