The Old Man Emu Rear Coil Spring Set 2617 is built to upgrade rear suspension performance on Jeep Wrangler JK models, especially vehicles that carry extra cargo, expedition gear, rear bumpers, or towing loads. These springs are engineered to provide improved load capacity and more consistent ride height compared to factory coils.
Manufactured from high-strength micro-alloy spring steel, OME springs are formed and pre-set using stress-reduction processes that help minimize long-term sag and maintain consistent performance over time. The spring rate is selected to balance load support with ride comfort, delivering stable suspension behavior both on-road and off-road.
Compared to standard rear springs, the 2617 set offers better resistance to compression under load, improved rear-end stability, and more predictable handling on uneven terrain. They are commonly used as part of a matched suspension system with performance shock absorbers for best overall results.
This spring set is well suited for daily-driven 4x4 vehicles as well as overland and trail builds that require dependable rear suspension support.
