KTM 890 Duke DukeR 790 HD Cylinder Head Stud Kit by EDR Performance Superhooligans

FINALLY A SOLUTION FOR WEAK HEAD GASKETS ON KTM TWINS!!

We are pleased to announce our custom HD Cylinder Head Stud kit availability for the KTM 790 and 890 engines.

We have found the oem cylinder head bolts lack the strength to hold up to big power and high speeds. Not only in the fact it is a bolt, instead of an actual stud and the material is an extremely low quality at best.  For the average everyday commuter they are fine, but for those of you out ripping these things HARD, racing them, track-days and such the head gaskets will start to fail!  Our custom ARP 8740 Chrome moly stud kit gives you much higher clamping load on the cylinder head so when the pressure is up due to higher heat, more load, higher speeds,  more compression and horsepower, your head gasket will hold! 

J-formed rolled threads after heat treat for maximum strength. Heat treated to deliver strengths of 180,000-210,000 psi!
