The TeraFlex 1402400 is a 4.5-inch coil spring base lift kit designed specifically for 2018-up Jeep Wrangler JL Unlimited 4-door models. This kit includes essential lift components to increase ground clearance and accommodate larger tires, but does not include shock absorbers or certain suspension geometry correction components that must be purchased separately.

What's Included:

• Front and rear 4.5-inch lift coil spring kits (TeraFlex #1864400 front, #1864300 rear)

• All necessary mounting hardware

Additional Components Required (Not Included):

• Front control arm sport brackets or adjustable short/long Alpine control arms
• Front and rear HD forged adjustable track bars to correct suspension geometry
• Shock absorbers - TeraFlex recommends their 9550 VSS twin-tube shocks or Falcon Performance shocks, which are engineered to work with these lift coil springs

Maximum Tire Clearance:

• Sport/Sahara fenders: 35-inch tires (with 3-inch front and 2.5-inch rear bump stops)
• Sport/Sahara fenders: 37-inch tires (with 3.5-inch front and 4-inch rear bump stops)
• Rubicon fenders: 37-inch tires (with 2.5-inch front and 3-inch rear bump stops)
• Aftermarket high clearance fenders: 39-inch+ tires (varies by fender design)

This base lift kit is ideal for Jeep enthusiasts who want to customize their suspension setup by selecting individual components, or who already own compatible control arms, track bars, and shock absorbers. The kit provides the foundation for increased ride height and improved off-road capability on JL Wrangler Unlimited models.
