The GKTECH Super Lock front lower control arms simplify, improve and replace the front lower control arm and compression rods on the 350z/G35, 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. We have replaced the dual OEM arms and made ours one piece. By switching to a 1pc design the kinematics are altered which makes for a design that will not bind at high angle and does not cause the steering to fall onto lock, both traits of the OEM 2pc design. Going to a one piece design also has allowed us to increase the caster angle by 2-3 degrees and this can be further increased by our front upper camber arms which have the adjustment to increase caster by up to 1 degree. These arms are adjustable, at their minimum length they start at 0.98' ( 25mm) over OEM and adjust out to 1.96' ( 50mm) from OEM. These arms have been designed with the OEM knuckle in mind, meaning they will work with our bolt on steering kit which uses the OEM knuckle. A limiting factor with the OEM LCA is the strut to knuckle position in that the brake caliper is prone to hitting the strut when on full on lock. To assist with clearance we have moved the strut mount further inward 30mm so this limiting factor is no longer prevalent. 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. We also include dust boots to protect the rose/ heim joints 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 - Reduced bind, being a 1pc design - Reduced ‘ fall to lock syndrome’ being a 1pc design - 2-3 degrees increased caster angle - Adjustable from 25mm to 50mm - Designed to be used with OEM knuckle - Strut mount relocated inward 30mm for caliper clearance - Adjustable link pin/ roll bar settings - High misalignment rose/ heim joints - CMM measured, CAD designed, FEA tested - CNC machined ends - Laser cut 4130 Chromoly steel design Vehicle Compatibility: - Nissan Z33 350z - Infiniti G35
