Brandon Bridges Verified Owner Friday, Sep 22 2023 (about 2 years ago) XRAY 48P Spur Gear “H” (87T) I dove deep into a rabbit hole of figuring out which spur gear worked best for my application (Dirt Oval).
This spur gear has been extremely strong holding up for multiple race days after stripping over 1 spur per race day on average from a competing brand.
This spur gear also runs truer than the other brands I tested.
The price is high for a spur gear, but not for how long it lasts. This is now all I run View all reviews
