Vortex SP614K Black 6mm Slider Swingarm Spool

I hate any type of aluminum on swingarm spools. Why? Because anodized aluminum doesn’t hold up and looks sketchy after just a few uses. Delrin is a trademark DuPont name but the principal is the same. Polyoxymethylene (Industrial plastic) works best and holds up extremely well. The outer and inner part of this spool is Polyoxymethylene and the part that comes into contact with your tool is soft aluminum. If they made this entirely of Polyoxymethylene they’d have a winner. BTW, the pitch on the bolts that with these spools is 1.25.

Awesome alternative to much more expensive axle block sliders and doubles as spools. ($120+ would be cheaper to replace the swingarm) They are 3 piece design to alleviate mounting hole sheering and allow puck rotation in event of a lowside. If you actually ride, you do NOT want 1 piece spool sliders! If solid piece design dig in, they will tear your mounting hole.

Not much to say about these but they are extremely solid, bolts are not cheap metal and the finish of the pucks is much more appealing then spools I have had in the past.Sits up on my pitbull stand with no issues! Thumbs up!

Son una estafa cuestan más de 30$ y son realmente pequeños y desechables

Had them on another zx6 and was totally satisfied that's why I reordered for a new zx6!

Perfect fit and functionality...

$34 for a light two piece plastic design is to expensive. Id prefer the sliders to be a one piece and some kind of rubberized material, because as of now it's more of a spool than a slider
