Product Description

The JKS Manufacturing JSPEC1257 1.5" Rear Coil Spring set is a straightforward, effective suspension upgrade designed specifically for 2020-on Jeep Gladiator JT 4WD trucks. By replacing the stock rear coils with these longer, dual-rate springs you gain approximately 1.5" of rear lift - improving ground clearance, rear wheel/tire clearance, and overall load-carrying capability. The dual-rate design keeps ride comfort smooth during normal driving, while offering firmer support when the rear is under load or navigating rough terrain.

Because the kit consists of a direct-fit spring pair (no other hardware required), installation is relatively simple and uses factory mounting points. This makes JSPEC1257 a practical choice for Gladiator owners seeking a modest lift for improved ride height, bed load capacity, or rear stance leveling - whether for light off-road, overlanding gear loads, or daily use with extra cargo.
