The Alpine IR Short Control Arm Kit, 8-Arm (0"-4.5" Lift) helps a lifted Jeep keep correct caster, pinion angle and axle position for predictable handling. It is built to take trail abuse while staying quiet and smooth on the highway. Part number 1416510 fits the 2018-2026 Jeep Wrangler.

Not Included:

Lift springs, shocks, track bars, long arm brackets (unless named in the title) and the alignment after installation are not included.

Features

Restores geometry after a lift
Control arm length and mounting points set caster and pinion angle, and these parts bring them back into range at the lifted height.

Adjustable or preset options
Alpine arms adjust to dial in alignment precisely, while Sport arms and brackets are preset for common lift heights.

IR bushing option
TeraFlex IR bushings rotate freely to reduce bind as the suspension flexes, which also allows torquing the arms with the Jeep in the air.

Serviceable bushings and joints
Replacement bushings, joints and a press tool keep TeraFlex arms in service for the long haul.

Heavy-wall steel construction
TeraFlex arms and tubes use thick-wall steel tubing built to handle rocks and heavy use.

Covers the Alpine short control arms on the JL. TeraFlex recommends doing the job with all four tires on the ground and never removing more than two arms at a time. On diesel models the exhaust blocks the passenger upper arm bolt, and the sheet describes lowering the exhaust or cutting that bolt. Arms are set to the lengths in the sheet and torqued at ride height unless they have IR bushings.
