2020 - 2024 CBR1000RR-R SP EDR Cylinder Head Stud Kit HD

EDR Performance is a leader in Performance & Engine Builds with multiple national championships, club championships around the world, HUNDREDS of race wins around the work, multiple track records, Daytona podiums and more. EDR built and tuned engines have always been the top placing and highest trap speeds in the MotoAmerica/AMA series year after year.  

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, that is a TTY and no reusable and very prone to failure when more power is added. These oem bolts are not great, instead of 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, roadracing them, drag or roll racing them, track-days and such the head gaskets will start to fail!  Our custom EDR design and spec 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! 

We have found the newest Honda's to be one of the most powerful engines out there, especially with our EDR ECU FLash. We have seen over 210 rwhp on them with stock engine components and even got them up to 220rwhp! However the head gasket does take a beating and typically will last only 1 season at best. Honda does not interagte the cyilnders into the upper crankcase so they are more prone to lose a HG before engines with 2 piece case/cylinders.

Now with our stud kit that is a non issue!  Also our stud kit has the ability to be used again and again during refreshes, unlike the cheap oem bolts your stock engine uses that are one time use. If you are going to push your Honda to the limit, insist on the best, EDR Performance Head Stud kits!
