4.5-Inch Front Dual Rate Coil Springs for Wrangler Rubicon 392

About this part

4.5-Inch Front Dual Rate Coil Springs, fitment-checked

Front springs for the Rubicon 392 at 4.5 in., dual rate and long travel. Spring rate matters more than usual on this model — the V8 sits heavier over the front axle than anything else in the JL range.

A spring calibrated for a standard Rubicon will sag under the 392's engine, which is why Skyjacker builds this one specifically for it. Dual rate long travel construction gives two rates in a single coil, so the Jeep stays compliant over small inputs and firms up as weight and articulation demand. Lift is 4.5 in. at the front. Coverage is the 2021-2022 Wrangler Unlimited Rubicon 392 in 4WD. This is the front component box — the rear is a separate order.
