The GKTECH Z34 370z Front Upper Camber Arms (FUCA's) are used to adjust the front camber or caster. When you lower your car negative camber is introduced which reduces the contact patch of your tyres and thus available traction. Our front upper camber arms will get this issue sorted!
These arms are a direct replacement of the standard arms and allow for negative -57mm through to +20mm of adjustment compared to the OEM arm.
On a stock lower arm we have seen camber as low as -5.0 degrees of camber and as high as +1.6 degrees!
As a completely unique design we have 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. We also include dust boots to keep the bearings protected.
- Adjustable on car without the need to remove the arm constantly adjusting
- Lightweight design
- High misalignment PTFE lined common size bearings
- CNC Laser cut from high strength steel with CNC machined ends.
- CAD designed, FEA tested and TIG welded
- Balljoint/ Inner wheel well clearance

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 -7.0 degrees of camber and as high as +0.7 degrees!
How long is the warranty on these arms?
All GKTECH suspension arms come with a lifetime warranty against manufacturing defects.
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 PCM12TThe outer bearing is a COM10T
Are there any special tools required?
No, a spanner set will do the job which we do sell separately here

Exactly what I needed; great quality and a good price.
I opened up the very taped up box. Some of the little black pieces were not zip tied like the other ones. And three pieces were there. One was missing. I emailed over pictures and let them know I had a piece missing and have yet to hear back from anyone.
Sorry to hear that some of the spacers were missing. I can see that Daniel replied to you within a few hours of receiving your email and you have now replied to that. As per that discussion, the missing pieces are being sent out express to you.
Very easy to install. Very easy to adjust. Thanks GkTech
Product was decent. Seemed to be reasonable quality but have had nothing but problems with the "spherical" bearing I believe it is called on the top where it bts to the knuckle. One driver even the bearing had play that almost had me fail my tech inspection for the next event. Had to order new bearings because I don't think I had cared to complain a ton BC they were cheap enough but to have play after just a single drift event was like, really...
Otherwise I was able to get the camber I needed but there may be a better way.
Hi Derek, sorry to hear that you had an issue with the bearing wearing prematurely. FYI we do warrant all of our arms and our bearings but often issues can come from incorrect setup (not saying it's necessarily the case but we'd prefer to rule it out). In this case, I would strongly suggest looking at is if you have the arms on the correct sides as if you don't, the bearing will run out of misalignment and that will cause premature wear of the bearing and could lead to the arm bending or failing entirely. We're always happy to help so please do reach out to the guys in customer service.
Love the way they feel and how responsive it made the car but there was a tapping noise couldn’t figure where it was coming from even raised the car up a lot and it still was making the noise not sure if normal sounds when going oem to aftermarket
Hi Kevin, going from OEM rubber bushings to spherical bearings will increase noise a little but a tapping noise is not normal. I would suggest investigating further. It's likely either you haven't set your bump stops on your coilovers and the top of the FUCA is making contact with the chassis or the FUCA making contact with one of the extended bolts that protrude from the engine bay side.
