TeraFlex standard rear lift coil springs use a linear spring rate for consistent performance throughout suspension travel. Choose the pair that matches your Wrangler's body style and required lift using the Lift height by body style selector.
Vehicle fitment
For 2007–2018 Jeep Wrangler JK 2-door and Wrangler Unlimited JKU 4-door models. For 2018 vehicles, confirm the JK body style; this listing is for JK/JKU applications, not the JL generation.
Lift-height guide
The same spring pair provides different listed lift heights on 2-door and 4-door vehicles. Match both your body style and the manufacturer part number before ordering.

What's included
One pair of rear coil springs: two springs for the rear axle. This is not a complete suspension lift kit; front springs and shocks are not included.
Spring design
TeraFlex tunes its JK/JKU lift springs around front-to-rear load balance and uses linear-rate technology for predictable handling on and off road. TeraFlex recommends pairing these springs with appropriately matched Falcon Performance Shocks.
Installation instructions by part number
Check the instructions for your selected spring pair and confirm the other suspension components required for your lift before installation.
