The GKTECH V2 350z/ G35 Front Upper Camber Arms (FUCA's) are used to adjust front camber and caster. When you lower your car negative camber is introduced. This then reduces the contact patch of your tires and thus available traction. Our front upper camber arms will get this issue sorted!

When designing these arms we were able to incorporate more clearance in the balljoint area from the inner wheel well by 0.39' (10mm) to assist when the upper arms are extended.

These arms are a direct replacement of the standard arms and allow for -0.98' (-25mm) through to 0.59' (+15mm) of adjustment compared to the OEM arm. With the OEM FLCA we have seen these arms adjust camber as low as -5.5 degrees all the way through as high as +1.0 degree! With our adjustable lower control arms we have seen as low as -11 degrees of camber showing a great range of usable adjustment.

As a completely unique design we have now made it possible to adjust caster, by using stackable shims it allows you to further increase adjustment by + or – 1 degree of caster.

These arms have been CAD designed, FEA tested, they are laser cut from high strength steel, are TIG welded and to finish the arms off they're E-coated (electrophoresis coating) for rust prevention. 

The arms feature high misalignment PTFE lined rose/ heim joints, that we use in all our suspension arms, that are a common size bearing that can be found at your local bearing supplier, or if you need we do have them on the shelf and the provided dust boots will ensure that the heims last the test of time.

- CNC Laser cut from high strength steel with CNC machined ends.
- CAD designed, FEA tested and TIG welded
- Balljoint/ Inner wheel well clearance

Vehicle Compatibility:

 Legal only for use in competition vehicles which may never be registered, licensed, and/or used on public streets or highways; and also for use in other exempted vehicles.


Will these fit my car?
We can only confirm fitment for the vehicles listed above under "confirmed fitment".

How do they adjust caster? 
We've made caster adjustable through stackable shims. By using larger shims in front of the bearing you are moving the arm backward (towards the rear) increasing caster, by using larger shims behind the bearing you are moving the arm forward and reducing caster. 

How much camber will they give me?
On a stock lower arm we have seen camber as low as -5.5 degrees of camber and as high as +1.0 degrees! With our adjustable lower control arms we have seen as low as -11 degrees of camber for those who want complete adjustment.

How long is the warranty on these arms?
All GKTECH suspension arms come with a lifetime warranty against manufacturing defects. This does not include crashes (it's pretty easy to tell the difference between a crack caused by impact as opposed to a stress fracture) and the Teflon lined rose joints come with a 1 year replacement warranty. We stock spare bearings so even after the 12 months is up we can still help with replacements, worse case scenario they're a 5/8" rose joint for the outer bearings and a COM10T inner bearing which are readily available through your local autoshop.

Are these suspension arms legal for use on street cars?
We recommend that you contact your local RTA for clarification/confirmation. 

Where can I find these common size bearings?
They can be found at any local bearing supplier as mentioned, however, we do keep them on the shelf so that the arms can be serviced.

The rose/ heim joints used, use part number PCM12T

The outer bearing is a COM10T
