Cylinder stud bolt set consisting of:

  • 4x stud bolt M7x158mm (thread length 20mm + 25mm)
  • 4x washer M7
  • 4x nut M7 (stepped)

Ideal set for cylinders which are driven with a thick spacer for a long connecting rod.
18mm longer than the standard bolts.
An ideal complement are the high-strength Naraku collar nuts which are much harder than the nuts supplied by Polini.

Optimal wenn die originalen Stehbolzen zu kurz sind

Diese Zylinderstehbolzen sind die Beste Lösung wenn man z.B.Zylinderköpfe mit höherer Verdichtung verbaut.

Leider nicht günstig, aber gut.

Diese Stehbolzen wurden in einer 150 VBB mit 125er PX Motor verbaut. Durch 60 mm Hub und Dichtungen waren mir dir 140 mm Stehbolzen einfach zu kurz. Bin mit dieser Qualität bei dem Preis sehr zufrieden!
