The new V2 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.
Speaking of limiting factor the V2 FLCAs feature robust, stackable shims as their lock stop, to stop the wheel exactly where you need it to be stopped.
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.
- Allow for 65+ degrees of steering lock
- Adjustable from +32mm to +72mm
- Designed to be used with OEM knuckle
- Strut mount relocated up to 50mm (adjustable) for caliper clearance
- Adjustable link pin/ roll bar settings
- High misalignment rose/ heim joints
- CMM measured, CAD designed, FEA tested
- CNC machined ends
- Laser cut 4130 Chromoly steel design
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.

What is a Backorder?
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.The new V2 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.

FAQs
How much angle can I get out of these LCA's?Our lower control arms can support around 65 degrees of steering lock!
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.
But apart from that, remove your standard LCA's and compression rods and the LCA's will bolt straight in.
What happens if a bearing needs to be replaced?
They are common sized bearings, which can be found at any local bearing supplier.
The ball joint bearing is a YPT12T
The rose/ heim joints used are a PCML12TS and a PCML12TES
However, we do have these on the shelf and can help out with replacements.
Are these suited to circuit/grip racing?
Yes, absolutely. These arms use of spherical bearings which do make them entirely useful for circuit/grip racing by eliminating bush deflection. Coupled with the built-in caster angle and the additional adjustment to increase track width.
Do I need to do any other modifications to get the most from these LCA's?
You can bolt them in as they are, however, you would only increase your track and caster angle.
Ideally, you would get these alongside our bolt on steering kit and either the bolt on rack spacers or the offset rack spacers.
This for drifting especially will give you a great deal of steering lock and be super smooth to drive with!
Will these fit my car?
We can only confirm fitment for the vehicles listed above under "confirmed fitment".
How long is the warranty on these arms?
All GKTECH suspension arms come with a lifetime warranty against manufacturing defects.
The PTFE lined rose/ heim joints come with a 1 year replacement warranty and as mentioned, they are a common size which can be found at any local bearing supplier, or we do keep them on the shelf!
Are there any special tools required?
No, a spanner set will do the job which we do sell separately here - Double open ended wrenches
Do you carry spare parts for this product?
Yes we carry the following spare parts for this product;
