After nearly 2 years in development, countless prototypes and revisions we have a lightweight yet strong drop knuckle for the S/R/Z32 chassis Nissan's. They come with dual caliper brackets as standard, high-quality PTFE lined spherical bearings throughout and have all new kinematics to drastically improve anti-squat, bump steer, camber gain curves and raised roll center height.
What makes these rear knuckles different to other drop knuckles?
Our rear knuckles are not just drop knuckles, they have different suspension arm mounting points which results in altered and improved camber curves and bump steer. This results in far more grip and very predicatble grip. Seperate to having all new kinematics these rear knuckles use spherical heim joints (a common size also incase you need to ever replace them), and have dual caliper brackets as standard.
Do these rear knuckles have clearance for GTR axles?
Yes, there is enough clearance for GTR axles.
Do you make these with a "fork" style strut mount?
We don't. We only make the version seen here.
How do I get the most out of these knuckles?
To get the most out of the kinematics improvements, an S14/S15/R33/R34 rear subframe is suggested. Alternatively, if you have an S13/R32 subframe you can use our anti-squat reduction weld in kit, if that has been done then suggested traction rod length for this is 225mm, measuring from centre hole to centre hole.
If you are running either;
S13/R32 subframe we recommend a traction arm length of 218mm measuring from centre hole to centre hole.
S14/S15/R33/R34 subframe we recommend a traction arm length of 203mm also measuring from centre hole to centre hole.
Do you make these with brake mounts to suit Wilwood calipers?
At present we are only making the 1 version of the rear knuckles which is for dual 2 pot Nissan calipers (R32, R33, R34, Z32 etc.).
Will these fit my car?
We can only confirm fitment for the vehicles listed above under "confirmed fitment" however also take note that as mentioned in the product description aftermarket traction, toe and camber arms are required and they must have heim joints for misalignment.
How long is the warranty on these rear knuckles?
All GKTECH suspension products come with a lifetime warranty against manufacturing defects.
The Teflon lined heim 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" spherical bearings and are readily available through your local autoshop.
Are these rear knuckles legal for use on street cars?
Our understanding is that any suspension arm with a spherical bearing is not legal for street use in Australia. However we do recommend that you contact your local RTA for clarification/confirmation. Whether you use these on public roads is at your discretion and we will not be held resonsible for the outcome.
