This does not fit Xray 2019 XB2D. Amain shows it will but they are mistaken. Correct part# for that car is XRAY365878

Great spurs! Perfectly round, and buttery smooth! Over a years worth of racing on turf with a 5.5!

What reviewers say

Three reviews with mixed results. One reviewer praises a 81T variant as round and smooth after more than a year of turf racing with a 5.5 motor. Two reviewers using the 78T variant report it does not fit Xray 2wd buggies or the 2019 XB2D; one says the bore is too small, and another says a supplier listing claims compatibility that is incorrect and gives a different part number for that car. The reviews point to a recurring fitment problem with the 78T variant, while the 81T has only one positive report.

  • + Round and smooth running
  • + Durable over a year of racing
  • − Does not fit some Xray 2wd buggies
  • − Bore reportedly too small
  • − Listed compatibility appears incorrect
