Different manufacturers use different measurements, which makes it difficult to compare parts with each other. Therefore we decided to unify how parts are measured on this page. Please be aware that we do not have every single part to confirm measurements. If you find that something has different measurements than in the description, please let us know - we are more than happy to update the listings to their correct, unified measurements.
We decided to go with metric measurements since most parts are measured this way anyway, and it's what most of the world uses.
Axle
Width: Axle width is measured from the outside of the hex nut to the outside of the hex nut on the other side. This is the best measurement because you will know exactly where the wheels will be mounted and what they might add to the width.
Weight: Weight of an axle is measured with all attachments like knuckles, steering links, and servo mount, but without any wheels and suspension links.
Links
Length: Link length is measured center-to-center between the mounting holes.
Compatibility
Compatibility is always to be considered from the stock SCX24 - and in regards to that, the one physical change that really matters are the link lengths - there are four in total:
- Lexus GX470 Specific 128.1mm (AXI-1800)
- Short/Medium/Long (AXI31613)
- Long Wheelbase 133.7mm (AXI204000)
- X-Long Wheelbase 153.7mm (AXI204001)
So every SCX24 model falls in one of those four categories. Of course some parts are only compatible with a specific model, like for example bumpers, but all more generic parts can be categorized in one of those four.
