Stack Performance Lowering Springs for Dodge Challenger


Stack’s spring design reflects our ability to develop a quality spring, increasing handling capability, giving your vehicle a very clean lowered stance, all while retaining excellent ride quality.

These springs feature increased spring rates for upgraded handling capabilities and superior ride quality. We have spent hours of development using a state of the art “Shock Dyno” to test and meet our requirements with proper spring ratings, to ensure zero spring sag.

Our springs are cold-wound on modern CNC coiling machines, stress relieved, pre-set, and shot-peened for maximum durability. Our springs are powder coated our “Signature Silver”.

Please allow 2-3 weeks for powder coated custom colors; Orange, Red, Blue, White or Purple. Call us at 562-905-0555 for custom colors not listed.

These lowering springs are designed to work with OEM shocks only.

We recommend all (auto-adjust) R/T Challengers to upgrade rear shocks to the SRT8 Bilstein.

Looking forward to working with you.
