Construction & Design

These coil springs are crafted from high-grade steel, ensuring strength and resilience under demanding conditions. The dual rate design means the springs have two distinct spring rates: a softer initial rate for comfort during normal driving and a firmer secondary rate that engages during heavy compression for superior off-road performance. This engineering approach reduces harshness on pavement while providing the support needed for rock crawling and trail riding.

Superlift applies a protective coating to resist rust and corrosion, extending the lifespan of the springs even in wet or muddy environments. Precision manufacturing and rigorous quality control guarantee consistent performance and fitment, making installation straightforward and reliable.

Installation & Fitment

Installation of the Superlift 4-inch Lift Dual Rate Coil Springs is designed to be a direct replacement for the factory front coil springs on 2018–2019 Jeep Wrangler JL 2 Door models. No major modifications are required, and the springs work seamlessly with the stock suspension geometry. For best results, it is recommended to have the installation performed by a qualified technician or an experienced off-road shop. Proper alignment after installation is essential to maintain handling and tire wear.
