The 2.5" Alpine CT2 Short Arm Suspension System, No Shocks (2-Door) lifts the Jeep and lets you fine-tune its suspension geometry for the tires and trails you run. HD forged adjustable track bars center the axles and tighten steering response. Part number 1522200 is built for the 2018-2026 Jeep Wrangler.
Not Included:
Shocks, steering stabilizers, driveshafts and the alignment after installation are not included; TeraFlex recommends Falcon shocks, sold separately.
Also required, sold separately: on 3.0L EcoDiesel models, the TeraFlex 1" Front Coil Spring Spacer Adjustment Kit (#1155100).
Features
Adjustable Alpine control arms
Alpine short arms set front caster, front and rear pinion angles, axle position in the wheel wells and wheelbase.
Centered axles, sharper steering
Forged HD adjustable track bars, with their relocation brackets, center the axles and optimize roll center for better steering response and less body roll.
Better geometry at height
The systems relax control arm angles and restore roll axis angles to reduce brake dive and acceleration squat.
Quieter than a basic lift
TeraFlex designs its Alpine systems to reduce noise, vibration and harshness on the road.
Choose your own shocks
Systems ship without shocks, and TeraFlex recommends Falcon shocks that are tuned alongside its lift springs.
Tiers for every build
Alpine CT suits owners who want adjustable geometry, while Alpine RT adds Independent Rotation bushings and more hardware for heavier trail use.

Installation
Type: Complete short arm lift system · Install: Shop recommended, some drilling and trimming · Afterward: Alignment and headlight aim
Work through the TeraFlex sheets in order for this system, set the control arm lengths to the recommended values, finish the torque at ride height, and have the alignment done afterward. TeraFlex recommends installation by a certified mechanic.
Swaps in the JL progressive jounce bumpers front and rear. The ABS and brake line anchor brackets come off the frame, and on Rubicon models the locker actuator is disconnected as well.
Torque: 56 ft-lb, shock bolts; 69 ft-lb, sway bar link bolts
Installs JL Alpine adjustable short control arms, set to TeraFlex's recommended lengths. Arms stay loose until the end of the install, and on diesel models the exhaust blocks the passenger upper arm bolt, so the sheet gives extra steps or the option of cutting that bolt and buying a Mopar replacement. If only one pair of arms is fitted to correct caster and pinion angle, TeraFlex recommends the lowers.
Tools named in the guide: Metric sockets and open-end wrenches, Torque wrench, General mechanics tools, Factory service manual
Torque: 59 ft-lb, sway bar link bolts; 74 ft-lb, lower shock bolts; 103 ft-lb + 145°, 21mm control arm bolt with 24mm nut, torque-to-angle; 30 ft-lb, 8mm adjuster clamp bolts; 41 ft-lb + 185°, 18mm fixed arm end at the axle, torque-to-angle

Torque: 52 ft-lb + 115°, 21mm track bar bolt, torque-to-angle; 60 ft-lb, 10mm clamp bolts; 52 ft-lb + 155°, 21mm axle-side track bar bolt, torque-to-angle
Installs the HD front lower spring perches on the JL or JT. The upper spring isolator's two alignment pins are cut off, and the brake line brackets come off the lower control arms.
Torque: 74 ft-lb, 18mm shock bolt and nut; 103 ft-lb + 145°, 21mm bolt with 24mm nut, torque-to-angle; 130 ft-lb, lug nuts; 59 ft-lb, 18mm bolt
JL 2.5" spring lift install. The brake line brackets on the lower arms are removed and discarded, the front axle actuators and vent hose are disconnected, and TeraFlex notes some form of caster correction is required with the base spring lift. Sport and Sahara models on 37" tires may need extra bump stop spacers, and EcoDiesel and 392 models have longer jounce tubes.
Torque: 130 ft-lb, track bar and lug nuts, with the Jeep on the ground; 66 ft-lb, 13mm bolt; 45 ft-lb, sway bar link hardware; 52 ft-lb + 155°, 18mm front control arm bolt, torque-to-angle; 74 ft-lb + 65°, 21mm rear control arm bolt, torque-to-angle

About TeraFlex
TeraFlex is a Jeep company at heart, started and staffed by people who drive them. It designs, engineers and builds suspension systems, shocks, axles and performance parts, with the Wrangler and Gladiator at the center of the lineup.
The company traces its history to the 1950s, when it began as MEPCO (Military Equipment Parts Company), one of the first companies anywhere to supply Jeep parts and accessories. TeraFlex Manufacturing followed in 1996 to build heavy-duty suspension for the TJ Wrangler, and the brand credits itself with the first suspension system for that coil-spring platform, a low-range gearing option for the 231 transfer case and the CRD60 high-pinion axle.
The current catalog covers full lift systems, the Falcon shock line and a long list of Wrangler and Gladiator upgrades, and the company is now carrying the same engineering approach to other vehicles as well.
