The V4 GKTECH Super Lock S-chassis front drop knuckles have been developed with the learnings from our previous 3 versions of knuckles and we now present a lightweight, sheet metal design after hundreds of hours of FEA (Finite Element Analysis) to improve the strength of the product but also keep the weight down.

These bad boys are able to achieve around 70 degrees of steering lock with ease!

They are not for the faint hearted being our pro knuckle and feature offset caster trail and adjustable Ackerman, that's right, adjustable Ackerman so that you can really dial in your front end and be unstoppable

- Spindle height raised 40mm's for roll centre and bump steer correction

- Around 70 degrees of steering lock

- Lightweight (S13 version is 3.1kg and S14/S15 is 3.15kg)

- S13 and S14/S15 specific versions

- Offset caster trail

- Adjustable Ackerman

NOTE: Our offset steering rack extenders offer an additional 19mm's of steering rack travel and help to avoid steering bind. They are required to get maximum steering lock and as such, are recommended.

NOTE#2: Steering lock of 70 degrees quoted is based on having wheel clearance. If you have high offset wheels and your wheel hits the chassis then you may get less than this amount of steering lock.

NOTE#3: Will not work with some brake caliper adapter kits.

NOTE#4: Does NOT have a provision for ABS

Best suited to be used with our Super Lock LCA's which can be seen here

FAQ'S

What's so good about these knuckles?

A lot of people think that the best thing about knuckles (aka uprights) is getting more steering angle to drift however the main advantage of installing knuckles is the roll centre correction and bump steer correction. Extremely lowered vehicles typically handle poorly, with drop knuckles like these installed the handling will improve dramatically as your lower control arm and castor (aka tension) rods are sitting near horizontally which brings them back to where they were before the car was lowered = good.

How do these differ to the V3 knuckles that you used to make?

The V3 knuckles have a shorter steering arm and also adjustable Ackerman to increase the amount of steering lock that is obtainable when matched with our Super Lock LCA's. Also, our V4 knuckles have in built caster trail.

How hard are these to fit?

They are quite easy to install but mechanical knowledge is certainly required. Remove your standard knuckles and the knuckles will bolt straight in.

Do you make knuckles for other cars?

We make knuckles for S and R chassis Nissans, we don't make them for any other cars.

How much angle can I get from these knuckles?

Depending on the width and offset of your rims, and whether you're running standard lower control arms or notched/modified lower control arms (or standard) you will see between 55 degrees - 70 degrees of steering lock. With the use of our Super Lock LCA's combined with appropriately sized wheels you will see around 70 degrees of lock.

Do I need to do any other modifications to get the most from these knuckles?

Yes, notched lower control arms or at least modified bump stops will help get more from the knuckles and rack spacers are recommended or alternatively longer tie rods or some of our tie rod ends (adjustable length) but to get the absolute most of these knuckles our Super Lock LCA's, our offset rack spacers (or rack relocated using bolt on rack spacers) and appropriately sized wheels are required.

Can I do backwards entries with these?

Good question, we have seen our customers do that with these knuckles!

Provided you have enough lock, clearance (and skill) we don't see why not!
