GKTECH - Z34 370Z / G37 4130 CHROMOLY SUPER LOCK LOWER CONTROL ARMS

The GKTECH Super Lock front lower control arms simplify, improve and replace the front lower control arm and compression rods on the Z34 370z/G37, 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.

These arms are adjustable, at their minimum length they start at +32mm over OEM and adjust out to +72mm 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 and added adjustability to allow the strut to be moved up to 50mm inward.

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.

Inner tie rod ends
Being that these lower control arms are longer then the OEM even at their shortest setting they do require the use of longer inner tie rod ends.

We do offer longer inner tie rod ends, however, they do use a different rack thread pitch to the OEM Z34 rack which is also why we list the conversion rack spacers in both a straight bolt on and offset rack spacer.

If you think you will run into steering bind with your setup, then the offset rack spacers are recommended. If not the straight bolt on rack spacers will do the trick!

The above options are only for the Z34/G37 only.

If you have a RZ34 Z then you would need to select the RZ34 Z inner tie rod end option as they are chassis specific.
