Q: What is backorder?

When a product is on backorder, it means that we have sold out and we are opening a back order due to popular demand. This is essentially a queue, when new stock arrives from production, we’ll send your order.

Q: Will items in my order that are in stock be shipped out first?

We will send your order altogether once your backorder item is ready! You may wish to place separate orders if you want an item before the other is due back in stock.

Introducing the ultimate drifting upgrade for the Z34 370Z! The GKTECH Super Lock Drift Knuckles are engineered to provide precise and predictable steering response while delivering up to 65 degrees of steering angle, they are not for the faint-hearted.

We've lowered the ball joint height to achieve a 30mm roll center correction while also relocating the tie rod pickup to provide faster steering, reduced ackerman and optimized bump steer. Alongside this, the ackerman is adjustable, giving either some ackerman or parallel steering and the bump steer is adjustable for those that want to dial their setup in.

The caster has been reduced which in turn reduces camber change through steering angle resulting in a flatter contact patch and more consistent steering feedback during drifting. The added caster trail makes up for the reduced caster to ensure that self steer remains desirable.

Our knuckles are constructed from 4130 chromoly steel which provides incredible strength while still being lightweight. They are specifically designed for aftermarket single-piece lower A-arms instead of the OEM two-piece virtual A-arm. To further enhance performance, we've added high misalignment PTFE lined spherical bearings throughout the knuckles.

FAQs

How can I tell if I have the V1 FLCAs or the V2 FLCAs?
There were many changes made but the easiest and most obvious change to check for is the lock stops. If you have the adjustable bracket then it is the V1 FLCA, if you have the stackable shim lock stop design, then it is the V2 FLCA.

What wheel/tyre specs are optimal?
Different wheel and tyre sizes can achieve different amounts on steering lock.

Through our testing the OEM Wheel being 19"x9.5"+40 - 255/40R19 achieved around 48degrees.

Although in saying that a fairly common size and offset would be 18"x9.5"+12 - 235/40R18 which achieved around 60degrees and would be our recommendation to have the best allrounder of lock and drivability.

On the extreme side of things, you could go 18"x9.0"+0 - 235/40R18 which you could see around 62degrees and 18"x9.0"-20 - 235/40R18 which is wild! But did see around 65degrees.

How hard are these to fit?
They are quite easy to install but mechanical knowledge is required and recommended.

We also include an assembly guide on most product pages, that can be seen above. You are also welcome to get in touch if you need help.

What's the difference between your "bolt on steering kit" and these Super Lock Drift Knuckles?
The main benefit between the 2 is the Super Lock Drift Knuckles have roll center correction, bump steer correction, optimised gamber gain through bump and droop, and they have reduced camber change through steering range (more consistent steering feedback).

Do I need to do any other modifications to get the most from these knuckles?
Yes, infact there are some prerequisites. You must be running aftermarket front upper camber arms with adequate inward adjustment. You must also run front lower control arms that are a 1 piece design like the ones that we make.

Does installing this kit require a wheel alignment?
Yes, it alters both toe so a wheel alignment will be required after installation.

Will this fit my car?
We can only confirm fitment for the vehicles listed above under "vehicle compatibility". If your car is not listed there, then we don't know if it will fit.

Can I install this myself? If so how long will installation take?
Yes, provided you have general mechanical knowledge as they are relitively straightforward. Installation time should be around 30 minutes. However, being a suspension component we recommend only a trained professional to install this product

Do I need bolt on rack spacers?
It is not completely neccessary, if you are chasing lock, then we do recommend the bolt on rack spacers this will allow for more travel of the rack, which results in more steering lock.

If you are not chasing steering lock and just want to have the other benefits that the Super Lock Drift Knuckles provide then the bolt on rack spacers are not a requirement.

Should I get offset rack spacers or bolt on rack spacers?
This boils down to your setup, if you have low offset wheels and adjustable arms already and feel as if, if you had more lock the steering may over center, then we recommend the offset rack spacers, as they still provide adequate rack travel while also mitigating over-centering.

If your setup is fairly standard and you just want to obtain more steering lock, then I would just recommend the bolt on rack spacers, which to date is adequate.

I already have inner tie rod ends that have rack spacers built in, should I get your bolt on rack spacers?
The aim of the game is to unlock the full potential of the steering rack through rack spacers. If you inner tie rod ends already have them built in, thats fine and they still can be used, but we do recommend checking if that is a limiting factor (assuming they are shorter then the ones we recommend) if they are then we suggest the bolt on rack spacers, because who doesn't like more lock right? ...... right!

Am I going to have any problems with an increase in lock with the Super Lock Drift Knuckles?
Being that the steering kit increases steering angle and changes the ackerman this in turn may cause a light to appear on the dash along with the engagement of VDC.

To circumvent this, we recommend to bypass the factory YAW sensor or you can unplug it entirely.

Note that disabling the YAW sensor may not be legal for road use, please contact your local RTA if this is a concern for you and or effects your intention of use.
