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.Free Shipping on orders over $250

The GKTECH axle spacers are CNC machined from billet aluminium and are concentric in design to ensure the perfect fit. Our V2 version goes between the driveshafts and the hubs and eliminates the need for longer bolts which under high loads can strip out.
We now have the option of a spacer as thin as 5mm which is perfect for lowered cars however when running extended LCA's, S14/S15 subframe in an S13 or running bolt-on dual caliper brake kits the 10mm-15mm are more suitable.
Without axle spacers the hub is moved out and as such the CV's become more and more prone to damage. These axle spacers resolve this issue.
Sold as a PAIR NOTE: Running 10mm or larger spacers will require you to modify the OEM axle nut in order to use the split pin.
Alternatively, you can run a suitable thread-locking compound. NOTE#2:The further that you space the hub out from the drive shaft the less spline engagement that you have.
For most cars this will not be an issue but if you're running high levels of torque and/or you have had issues with stripping splines in the past then please keep this in mind.
FAQs
Will these fit my car?If you are unsure please measure the spline on your axles but unless your car is a GTR or a Z32 TT, or you know it's been upgraded then it will most likely have non GTR/Z32 TT axles (it's an expensive upgrade so isn't all that common).
Do you make these in other diameters or widths?
We're not making these in any other sizes at this point in time.
Do I need these?
If you are moving your hub out for any of the following reasons: running a dual caliper bracket, you're running extended LCA's or you're running an S14/S15 subframe in your S13.
Ideally the amount that you're spacing out your hub, you want to space out your drive shafts.How do these compare to the bolt on kind that you used to make?The bolt on kind under high loads was prone to destroying the supplied grade 12.9 hardware.
The slip in spacers don't have this issue however they do reduce the spline contact between the axle and the hub. Ie. the spline is 2.36 (60mm) in length so if you add a 0.19 (5mm) spacer then you're reducing the spline contact by 8% or going to the 0.59 (15mm) spacer reduces the contact by 25%.
This shouldn't be an issue for most cars but there is the increase in chance of stripping splines (albeit we haven't seen it happen).
