The GKTECH Super Lock front lower control arms simplify, improve and replace the front lower control arm and caster rods on the FR-S / GR86 or BRZ, while also supporting around 65 degrees of steering lock. These arms are designed based off CMM data, they are CAD designed, FEA tested, have CNC machined ends and the main body is laser cut and bent from 4130 Chromoly Steel. Adjustable, with 2 different length options; OEM length and adjust out to 30mm from OEM or; 40mm through to 70mm over OEM length. Designed with the OEM knuckle in mind, meaning they will work with our bolt on steering kit which uses the OEM knuckle. We still use, as we do all our arms, common sized PTFE bearings throughout the arm, which can be found locally, however, we do have them on the shelf should you wish to carry spares. We also use our high misalignment rose/ heim joints to allow the arm to rotate freely. Dust boots to protect the rose/ heim joints are included and have lock stops built into the arm for those that want to dial down the fun. Finally, the arms are E-coated (electrophoresis coating) for rust prevention. - Allow for 65 degrees of steering lock - Adjustable from OEM length through to 30mm or 40mm through to 70mm - Designed to be used with OEM knuckle - Adjustable lockstop - 3 swaybar mounting positions for adjustment - On car caster adjustment (6.75 default, max 10.2, min 4) - High misalignment rose/ heim joints - CMM measured, CAD designed, FEA tested - CNC machined ends - Laser cut 4130 Chromoly steel design Vehicle Compatibility: - Scion FR-S - Toyota ZN6 GT86 - Toyota ZN8 GR86 - Subaru ZC6 BRZ - Subaru ZD8 BRZ NOTE: OEM end links can not be used with these LCA's.
