Product Description

The Old Man Emu EL101R rear leaf spring is engineered to deliver enhanced ride quality, improved load carrying capability, and long-term durability for 2015-2020 Chevrolet Colorado models across 2WD and 4WD configurations. Built with a robust two-stage leaf pack and fully scragged leaves, this rear spring helps maintain rear posture under load while offering predictable suspension performance in everyday driving and light-to-medium hauling conditions.

Featuring draw-tapered and diamond-cut leaves with bolted leaf clamps, re-greasable nylon anti-friction pads, and a flat axle seat design, the EL101R minimizes noise, wear, and frustration from leaf clutter while maximizing strength and stability. The military wrap design and shot-peened tension sides further enhance structural integrity for dependable service life. Sold individually, this leaf spring pack is ideal for replacing worn or sagging factory springs or upgrading the rear suspension for better load support and handling dynamics. Installation requires standard suspension tools, and professional alignment after installation is recommended for optimal ride and tire wear.
