love the blue great locknut but don't know why it comes in a six pack.

Bobby RVerified owneron Team Losi Racing 4mm Aluminum Serrated Locknut Set (6) (Blue)

Work well until about the 10th tire removal (the small plastic eyelet pops out the center) which basically means they work great if you solely use them to race and not for everyday use. I like them, just not for that price when my stock set lasts 3x's longer.

These hold on really well to the rim!!! Never had one back off so far. And very light weight, less rotating mass

What reviewers say

Three verified owners of the blue 4mm aluminum serrated locknut set (six pack) rate it 3 to 5 out of 5. Reviewers praise the blue colour, a secure hold on the rim with no backing-off reported so far, and light weight that reduces rotating mass. One reviewer reports the small plastic eyelet popping out of the centre after about ten tyre removals, which they say limits the locknuts to racing rather than everyday use. That reviewer also finds the price high compared with a stock set that lasts about three times longer. One reviewer questions why the set comes in six. Sample size is small.

  • + Holds well on the rim
  • + No back-off reported
  • + Light weight, less rotating mass
  • + Blue colour
  • − Plastic eyelet pops out after about 10 tyre removals
  • − High price relative to stock locknuts
  • − Best suited to racing rather than everyday use
