The GKTECH V2 High Clearance LCA's are designed as a direct replacement for an OEM style LCA but with adjustment and loads of tie rod clearance! Our Budget LCA's are great for someone that already has caster rods or wants caster rods as a separate piece. Even with the addition of our V4 high clearance caster rods, the cost of going this route is around 25% cheaper. The arms offer 25mm of adjustment, will support 70 degrees of steering lock, you can still run an OEM style swaybar and a lock stop has also been incorporated into the design. They are also based on CMM data, are CAD designed, FEA tested, have CNC machined ends and the main body is laser cut and CNC machined 16mm thick chromoly steel for maximum strength. To finish the arms off they're E-coated (aka electrophoresis coating) for rust prevention and we're exclusively using Teflon lined bearings with dust covers for increased longevity. - Direct replacement of the OEM LCA - Feature 5/8" Teflon lined sphericals (inner) which eliminates the flex found in factory rubber bushing offering a more direct and predictable feel. - Laser cut and CNC machined from 16mm thick 4130 Chromoly sheet. - CMM measured, CAD designed, FEA tested and CNC machined. - Choose between 3 different lengths; 0 > 25mm 20 > 45mm 40 > 65mm NOTE #1: The 0> 25mm are based off S13 lower control arms, meaning at their shortest they are OEM to S13 lower control arms, if you are fitting these on an S14/S15 the specs will be -9mm > 16mm from OEM. The 20 > 45mm or the 40 > 65mm are based off S14/S15 lower control arms, so if you are running these on an S13 they will be 9mm longer. NOTE #2: All the lca's have the tension rod in OEM position, to counteract the 25mm adjustment for each length of LCA one of the mounting holes has been elongated.
