Lift coil springs are perfectly engineered for your 4-door JL Jeep Wrangler Unlimited. Engineers focused on extensive rate tuning and dynamic balance between front and rear and side-to-side load bias to produce lift coil springs that deliver unsurpassed highway handling and off-road performance. Up front they chose progressive dual-rate lift coil springs that provide optimal performance both on and off road. These progressive dual-rate coil springs provide consistent performance and predictable handling throughout normal street driving – just like a linear rate spring. When the axle begins to droop the softer sprung upper section of the coil spring begins to unwind for maximum flex and spring retention.

Specs:

• Lift height: 3,5”
• Powder coated for superior element protection
• Shot peened to reduce spring sag and fatigue as well as increase life
• These heavy duty lift springs provide a firmer ride with an empty payload

• (2) Front progressive coil springs

Notes:

3.0L EcoDiesel V6 models require the 1" Front Coil Spring Spacer Adjustment Kit TX1155100 to properly level the vehicle (sold separately)

The specified lift height is not the actual final lift height. Use the coil spring lift height descriptions as an average lift height that can be achieved. Other variables will affect the actual final lift height, such as a winch, steel bumpers and other 4x4 accessories
