Had to replace a broken name brand spring. This one has held up for 4 races in my gokart so far.

Ich finde diese Ventilfedern sehr gut waren einfach zu installieren aber man bräuchte ein Ventilfederkompressor um die Einzubauen, außer man möchte sein Finger opfern, die sind bisher nicht kaputt gegangen und lassen denn Motor mehr als 7000 Umdrehungen drehen, ich hatte es gemessen mit einem Umdrehungsmesser es waren irgendwie so zwischen 7,500-8000 Umdrehung aber ich finde es sehr gut

installed these 26 lb valve springs on a Predator 212 build that’s running a performance cam, billet rod, billet flywheel, and governor delete. Stock springs start floating valves way too early once you raise RPM, and that’s exactly the problem these fix. First thing I noticed is the spring quality. The wire diameter and finish look consistent, no weird bends or uneven spacing. They dropped onto the retainers without any fitment issues. Definitely recommend using a valve spring compressor tool — trying to do these without one is just frustrating.
