Does the kit for the 4Xe work for the EcoDiesel? I see SKU 1862003 is the same front coil for both drivetrains on the Teraflex site and am hopeful this can be an option. Thank you
No, the 4xe-specific kit will not work correctly on the EcoDiesel model.
While both the 4xe and the EcoDiesel add substantial weight compared to standard gas engines, they distribute that weight differently and require distinct front coil spring rates to achieve the proper ride height and prevent front-end sag. Teraflex manufactures separate, drivetrain-specific part numbers to account for the unique weight and handling characteristics of each power plant.
If you are looking to lift an EcoDiesel model, you will want to source the diesel-specific version of the suspension system (such as Teraflex part # 1612020 for their standard Sport ST2 kit) to ensure proper leveling, geometry, and performance.
This would be the correct part number: Teraflex 1612020 Sport ST2 2.5in Suspension Lift for 18-27 Jeep Wrangler JL Unlimited 4-Door with 3.0L Diesel

is this a level lift to eliminate factory rake.
Yes, absolutely! The Quadratec ST2 2.5" Suspension Lift by Teraflex is designed to level out your Wrangler JL and completely eliminate that factory front-end rake.

Does this kit fit 2018 JL. 2.0 with etorque option
Yes, the standard Quadratec ST2 2.5" Suspension Lift by Teraflex for 18-26 Jeep Wrangler JL Unlimited 4-Door is designed for the standard 3.6L V6 and 2.0L Turbo gas engines, but if your 2018 JL 2.0L has the eTorque mild-hybrid system, you need to double-check the spring rates.
Because the eTorque system adds extra weight to the front end compared to a non-eTorque 2.0L, using a standard gas kit can sometimes lead to slight front-end sag or a slightly lower lift height up front. Teraflex and Quadratec generally recommend matching your specific engine configuration to ensure you get the exact right coil spring rates for a level stance and proper ride quality.

Would this work with 2.0 liter Etorque
Yes, the Quadratec ST2 2.5" Suspension Lift by Teraflex for 18-26 Jeep Wrangler JL Unlimited 4-Door will work with the 2.0L turbo engine.
Teraflex does not offer a separate, dedicated part number explicitly labeled "eTorque." Instead, their standard 2.0L/3.6L gas spring rates (such as part # 14551210822411504531 are engineered to accommodate the additional weight of the 2.0L eTorque mild-hybrid system.
If you are loading the front down with an aftermarket steel bumper or winch alongside the eTorque battery, many Wrangler owners step up to the Diesel / 4xe / 392 specific spring rate variants (which use heavier-duty coils) to prevent any noticeable front-end sag.

Is there a recommended geo correction bracket for this lift kit?
The short answer is no, a geometry correction bracket is not required or typically recommended for this specific lift kit because caster correction is already built into the box.

What are the load/weight capacities for the included shocks and coils?
The included coil springs and shock absorbers in the Quadratec ST2 2.5" Suspension Lift by Teraflex do not have a specific published "weight capacity" rating.
Instead, they are designed and rated to handle the standard vehicle weight of a 4-door Wrangler JL along with typical accessory weight additions—such as heavy-duty steel bumpers, a winch, and a full-size spare tire—while maintaining the proper 2.5-inch lift height and factory-like ride quality.

Will this kit fit a 2021 Wrangler 392?
While it will bolt up, it is not recommended. Because the 641-horsepower 6.4L V8 Hemi engine adds significant front-end weight compared to standard JL configurations, installing standard springs will cause the front end to sit lower and sag under the extra load, failing to yield the true 2.5-inch lift height. If you want to lift a Wrangler 392, you need to ensure you use a suspension system specifically weight-rated and engineered for the heavier front-end loads of the V8, Diesel, or 4xe models.

I have a 21’ Jeep Sahara 4door 4XE, will this lift work? It give the option to choose the 4xe version but are the springs rated for the extra 4xe battery weight?
Yes, if you select the dedicated 4xe-specific option, the Quadratec ST2 2.5" Suspension Lift by Teraflex features coil springs specifically rate-tuned to handle the extra weight of the hybrid battery system on your 2021 Wrangler Sahara 4xe.
Model Specificity: Teraflex engineers distinct spring rates for the heavier 4xe powertrain so the vehicle maintains its proper ride height and suspension travel without sagging.
Included Components: This lift kit features Falcon SP2 shocks and front lower sport control arms to correct caster angles.

I’m about to purchase this lift kit should I also purchase the 1/2” spacers so it sits level also do I need rear track bar bracket.
The Quadratec ST2 2.5" Suspension Lift by Teraflex is designed to sit level on its own, so 1/2" spacers are only needed if you carry heavy rear gear or a winch. You do not need a separate rear track bar bracket because a matching bracket is already included in the kit.
