Yes. Mopar is Stellantis's (formerly FCA/Chrysler) factory service-parts brand. The coil spring carries the same OEM part number used by Chrysler, Dodge, Jeep, Ram, and Fiat dealerships — same metallurgy, free length, spring rate, and corrosion coating as the spring that came on your vehicle originally.

Industry best practice is to replace in axle pairs (both fronts or both rears). Springs on the same axle have worn at the same rate; replacing only one creates an uneven ride height, unequal handling balance, and puts premature stress on the new spring. Mopar sells matched springs so part numbers are consistent across a pair.

No. Using a genuine Mopar part — identified by the OEM part number — preserves your factory warranty under the Magnuson-Moss Warranty Act. Aftermarket springs can complicate warranty claims if a dealer argues the non-OE part contributed to a related failure.

Yes, a spring compressor is required any time the spring is removed from a strut assembly or a non-independent rear axle perch. Coil springs store enormous energy — an improperly compressed spring can cause serious injury. Rent a dual-hook or internal compressor from an auto parts store, follow torque specs in your factory service manual, and never release spring tension with the strut disassembled on a work bench rather than clamped in a vise or on a spring compressor stand.
