Pro Kit Mustang GT350 Set of 4 Springs

The Pro Kit Mustang GT350 Set of 4 Springs by EIBACH is purpose-built for enthusiasts and performance shops seeking predictable chassis dynamics and precise ride height control on fifth-generation Mustang GT350 platforms. These coil springs replace OEM units and form the foundation of any serious suspension upgrade, whether you're dialing in track geometry, reducing body roll, or achieving a more aggressive stance. As a seasoned mechanic, you'll recognize that spring selection directly influences suspension geometry angles—camber, caster, and anti-squat characteristics all shift with ride height—making this component non-negotiable for coherent suspension tuning.

EIBACH's Pro Kit springs utilize linear or progressive rate designs engineered to maintain consistent spring force across the suspension travel envelope, eliminating the harshness and bind common to poorly matched aftermarket units. The set of four springs ensures symmetric front and rear load distribution, critical for maintaining differential wheel rates and predictable under/oversteer balance during sustained cornering or trail-braking events. Superior material quality and heat-treatment processes resist fatigue and coil bind, allowing drivers to maximize suspension droop without risking spring failure—a common failure point in budget alternatives. Weighing 39.7 lbs for the complete set, these springs are lightweight enough to reduce unsprung mass while retaining the structural integrity demanded by high-performance driving.

The Pro Kit Mustang GT350 Set of 4 Springs is ideal for owners upgrading from factory or worn suspension systems, track-day competitors, and restoration shops modernizing aging platforms. Installation pairs seamlessly with aftermarket coilovers, dampers, or strut assemblies—verify your suspension platform architecture before ordering to confirm direct fitment. Many shops route these springs through comprehensive suspension refreshes that include updated sway bars, control arm bushings, and alignment protocols to maximize their performance potential. With proper installation and regular inspection, expect years of reliable service without loss of ride quality or resonance issues.
