Synergy Mfg 8864-60 Rear Lift Coil Springs for 18-26 Jeep Wrangler JL

Vehicle Fitment

• 2018-2026 Jeep Wrangler JL (2-Door and 4-Door/Unlimited)

Fitment Notes

• Rear position only - this is not a front/rear kit; a corresponding front spring must be purchased separately if a full lift is intended
• Lift height for this specific suffix (-60) was not directly confirmed in available sources - based on the established pattern across the 8864 family (8864-10/20/30 confirmed at 2"/1", 3"/2", and 4"/3" respectively), 8864-60 is most likely 7" (2-door) / 6" (4-door), consistent with Synergy's equivalent JK-generation part. Confirm directly with Synergy or a dealer before ordering if the exact lift height is critical to your build
• Unique to the JL platform - not shared with or interchangeable with JK Wrangler springs, despite similar part numbering conventions
• Lift heights are based on fully loaded Rubicon models; other trims will see more lift than the stated figure
• Requires proper bump stop spacing (Synergy 8057-10 Bump Stop Spacers) to prevent the springs from reaching coil bind - do not install with less spacing than specified

Features

• Designed from a clean sheet specifically for the JL platform's coil spring geometry
• Multi-rate spring design - soft initial rate prevents the spring from working loose in the coil tower, even with long-travel shocks
• Slightly stiffer ride rate than OEM to account for added weight from bumpers, winches, skid plates, and other common Jeep accessories
• Left and right specific springs, front and rear, to keep the vehicle sitting level like factory
• Shot-peened construction to reduce spring sag and fatigue over time
• Black powder-coated finish for corrosion resistance and a clean appearance
• Retains the vehicle's stock rake
• Manufactured in the USA from high-quality steel
• Backed by Synergy's lifetime warranty against defects in materials and workmanship

Specifications

• Position: Rear (pair - left and right specific)
• Spring Type: Multi-Rate
• Estimated Lift Height: 7" (2-Door) / 6" (4-Door) - inferred from product family pattern, not directly confirmed for this SKU
• Finish: Black powder coat
• Weight: Approx. 23+ lbs (varies by lift height in the family)

Included Components

• 2x Rear Coil Springs (left and right specific)

Product Description

Unlike the outgoing JK, the JL Wrangler's coil spring geometry required Synergy to design this spring family from scratch rather than carry over a JK-compatible part. The 8864 series result is a multi-rate rear spring that starts soft - preventing the spring from rattling loose in the coil tower even with long-travel aftermarket shocks - before ramping up to a ride rate slightly firmer than stock, accounting for the added weight of winches, bumpers, skid plates, and other trail gear most lifted JLs carry.

Left and right springs are unique lengths, mirroring how Synergy (and Jeep from the factory) accounts for corner-to-corner load differences so the vehicle sits level rather than leaning to one side. Shot-peened construction and a black powder-coat finish are built in for long-term fatigue resistance and corrosion protection, and the spring retains the JL's stock rake rather than altering the vehicle's factory stance angle.

This spring suits JL owners building toward a taller lift than Synergy's lower-height options in this family provide, whether for larger tire clearance or increased approach/departure angles on the trail. Given the lift height for this specific -60 suffix wasn't directly confirmed in my research, I'd strongly recommend verifying the exact figure with Synergy directly before finalizing this listing - getting that number wrong in a product listing is the kind of detail that generates returns and complaints fast.
