AEV NTH21131AB 3.5-Inch Front Coil Springs for Jeep Wrangler JK 2-Door (JK72)

The AEV NTH21131AB is a pair of frequency-tuned, progressive-rate front coil springs engineered to deliver 3.5 inches of lift for the 2-door Jeep Wrangler JK (JK72). These springs are a core component of AEV's renowned DualSport SC suspension system and are also available as a standalone replacement for owners who need to refresh or upgrade their existing setup without purchasing a complete kit.

AEV brings OE-level suspension engineering to the aftermarket, and these springs reflect that commitment. Spring rates are specifically tuned for the 2-door JK's unique curb weight and wheelbase, ensuring the correct balance of ride quality, load capacity, and handling that would be impossible to achieve with a one-size-fits-all spring.

Key Features:

• 3.5-inch front lift designed specifically for the 2-door Jeep Wrangler JK (JK72)
• Progressive/frequency-tuned rate for a compliant ride when unloaded and increased stiffness under heavier loads
• Vehicle-specific tuning — spring rates are calibrated for the 2-door JK's distinct weight and geometry
• Direct replacement for worn or damaged DualSport SC front springs without buying a full kit
• Sold as a pair (2 front springs)
• Backed by AEV's 1-year limited manufacturer warranty

Whether you're restoring your DualSport SC system or building a custom lift setup, the AEV NTH21131AB front springs deliver the proven on-road manners and off-road capability that AEV suspension systems are known for.
