The GKTECH Z33 Super Lock front lower control arms (LCA) simplify, improve and replace the front lower control arm and compression rods on the 350z/G35, 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.

We have replaced the dual OEM arms and made ours one piece. By switching to a 1pc design the kinematics are altered which makes for a design that will not bind at high angle and does not cause the steering to fall onto lock, both traits of the OEM 2pc design.

Going to a one piece design also has allowed us to increase the caster angle by 2-3 degrees and this can be further increased by our front upper camber arms which have the adjustment to increase caster by up to 1 degree.

These arms are adjustable, at their minimum length they start at 0.98' (+25mm) over OEM and adjust out to 1.96' (+50mm) 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 30mm so this limiting factor is no longer prevalent.

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
- Reduced bind, being a 1pc design
- Reduced ‘fall to lock syndrome’ being a 1pc design
- 2-3 degrees increased caster angle
- Adjustable from +25mm to +50mm
- On car adjustable in both length and caster
- Designed to be used with OEM knuckle
- Strut mount relocated inward 30mm 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

NOTE
- On low cars with the arms at their shortest length, please ensure you have adequate clearance between the arm and the subframe.

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's the difference between your V1 and these V2?
After selling over 500 sets of our V1's we have added the much requested "on car adjustment". Caster can now be adjusted in situ without the need to disconnect the heim joint for adjustment. We have also made the V2 arms stronger to cater for high loads that the FLCA's can see when drifting. Adding on car adjustment will save you time and money at the wheel alignment shop and make track side changes very quick and easy. 

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".

What happens if a bearing needs to be replaced?
They are common sized bearings, which can be found at any local bearing supplier.

The coilover bearing is a COM9T
The rose/ heim joints used are a PCML12TES

However, we do have these on the shelf and can help out with replacements.

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 - open ended wrenches

Do you carry spare parts for this product?
Yes we carry the following spare parts for this product;
Replacement COM9T Spherical Bearing - Spare part can be found here

Replacement PCML12TES Heim - Spare part can be found here

Absolutely Incredible

These lower control arms are a complete game changer. Absolute essential for anyone looking to seriously drift their z33 chassis. Tons of adjustment to get all the camber and caster you need, and gets rid of the annoying “falling onto lock” problem that the stock front end faces. Say goodbye to random spin outs and heavy steering at high angles, and say hello to holding high angle and predictable/controllable steering. Absolutely incredible product.

GKtech V2 LCA & Extended Tie Rods

10/10, extremely great product, gave me so much camber, adjustability on sway war, caster, camber, toe, etc! Couldn’t be any happier, now i wish i would’ve ordered the angle kit as well.

FLCA big issue!!

Put these on the car initially didn’t have too many problems with them besides the bump stops never even come close to any part of the FLCA but whatever. Been about a year on the car mostly in the garage when not driving and I noticed yesterday they have rusted over a good portion of both FLCAs as well as the ptfe bearings. Pretty pissed considering how much these cost.

Hi Austin, sorry to hear that you had an issue with them rusting. If you can send through photos and I will chase up with the guys in production.

The best part on my car

I did the install myself without any real issue. I wish it had been more clear to me that I'd need the extended tie rods (I had to run with toe out until they came in), but that may have been my oversight. While it logically follows knowing that these increase the track width, it wasn't something I considered as these are my first suspension mod.

That complaint aside, these are amazing. The steering feel is very different. It used to be heavy. I liked the heaviness because I felt it conveyed the heaviness of the car accurately. Now the steering feel is light and I realize it's because these bearings/joints don't have the rubber deflection and are transferring the forces more directly and smoothly.

These went on my daily because I was tired of replacing stock arms and figured "hey, these are serviceable so at least if one part wears out, I can replace that part. in the long run these are the right choice". I aim to do autocross and then drift.... get coilovers.... so these were an obvious early supporting mod

I'm happy
