Keep Your Truck Level on Every Trip: Medium-Duty Rear Leaf Springs

When you’re hauling gear or setting up for an off-road trip, sagging suspension can throw everything off. The Old Man Emu medium-duty rear leaf springs add steady support and about 1.5" of lift to maintain a level stance and better ground clearance. With a progressive spring rate of 213/558 lbs/in, they balance firmness under load with comfort when running light—so you stay stable whether you’re loaded with tools or camping gear.

Smooth Ride and Confident Handling: 2-Stage Progressive Design

Rough roads and uneven loads can make your truck bounce or sway. These 2-stage progressive springs adapt as weight increases, providing a consistent, controlled ride without harshness. The added firmness keeps the rear planted for stable handling on highways and trails while still soaking up smaller bumps for comfort when unloaded.

Built Tough for Years of Use: Shot-Peened Steel Construction

Durability matters when you depend on your suspension every day. Each spring is made from shot-peened steel to resist fatigue and extend service life. Greasable nylon leaf liners reduce friction between leaves, cutting down noise and wear over time. With a 3-year warranty backing them up, these springs are built to handle real-world miles.

Straightforward Replacement Fit: Works with Existing Hardware

Installing the upgrade doesn’t have to be complicated. These springs fit your current shackles and bolts—just give the hardware a quick inspection before reuse. Replacement bushings (OMESB117) and U-bolts (OMEU82) are available separately if you want everything fresh. Each spring weighs 52.25 lbs with a free arch of 9.09" and stack height of 2.2", giving you a solid, ready-to-work setup that feels right from day one.
