Synergy MFG has designed these springs from a clean sheet for the new Wrangler platform. All springs are multi-rate and have been designed to make a great platform even better.

These springs are unique to the JL and not shared with the JK or other vehicles. Like OEM, Synergy coil springs are unique lengths to account for load differences on each corner of the vehicle. There are right and left specific springs front and rear to guarantee the vehicle will sit level.

Part Number: 8863-30

Features

• Multi-Rate coil springs allow for longer spring lengths and increased travel
• Spring rates are only 5-10% stiffer than stock for superior ride quality
• Coil spring block heights designed around common bump stop spacings to optimize wheel travel
• Ground and closed lower spring ends to prevent bowing
• Includes front lower coil spring isolators to match the ground and closed spring ends
• Unique spring lengths for each corner of the vehicle so it will sit level side to side
• Frequency balanced and tuned spring rates to maximize suspension performance on and off road
• Abrasion-resistant black powder coat finish for maximum durability and corrosion resistance
• Sold in pairs
• Closed & ground coil spring bottom to make it perfectly flat
• Slightly increased spring rate (less than 10%) in order to accommodate for the added weight of the typical accessories and armor (winches, bumpers, skid plates, gear, etc.)
• Synergy's shortest springs will allow for around 12" of wheel travel front and rear. Taller springs will allow for more wheel travel.

Notes

• Coil springs require proper bump stop spacing with Synergy 8057-10 Bump Stop Spacers.
• Lift heights are based off fully loaded Rubicon models. Other models will see more lift.
• Coil springs retain the stock rake of the vehicle.
• Min bump stop spacing listed is the minimum amount of bump stop spacing required to prevent the springs from going into coil bind. Do not use less bump stop spacing.
•  If you want the vehicle to sit level (without the stock rake) when unloaded, our front coil springs will accommodate up to a .75" front coil spacer without requiring additional bump stop spacing (8017-075). This means that the ride height and rake of the Jeep can be fine-tuned in order to get the perfect ride height without compromise.
• Make sure the shock mounts and bump stops are setup to prevent the shock from bottoming out before the bump stops do. If using the stock front driveshaft, do not use shocks with an extended length greater than 29 inches. The driveshaft may contact the cross member and the stock Rzeppa joint will be damaged due to over-extension.
