The forward leaning K-series engine has long been considered necessary to be competitive in an “all motor” series drag car.  However, you need most HP per dollar for the best performing K-series side exit header. That is why Skunk2 Racing has introduced their ultimate free flowing, 4-1 K-series side and hood exit race header. This single kit has all the components you need for the option of having a side or hood exit header installation.

This incomparable header is engineered to produce a broad powerband starting with equal length primary tubes, then optimized using Skunk2's proven step design which capitalizes on the true merge collector and finishes with an exacting choke point to achieve that optimal powerband. This Skunk2 lean header is proven for powerful 500+hp engines, particularly with strokes from 99mm to 108mm, and constructed to last with meticulously Tig Welded 304 stainless steel - for that run-after-run performance.

Currently, the Skunk2 Racing side/hood exit header fits EG, DC2, and EK chassis's with Hasport lean mounts only. If you do not already have “lean mounts” you can purchase them HERE and HERE.

If you are racing a forward lean K-series engine in the All Motor class, you need this header!

No angle for correct throwing
Size: 1-pack, Size: 1-pack
This item does not work. It is about ) inches tall. It’s tiny to bend over and pick up the ball. Has no angel for the ball to throw accurately. Ball goes downward. Would not recommend

Cute, fun treat that’s perfect for a dog’s birthday
Flavor Name: Boy, Size: 8 Count (Pack of 1)
This Thoughtfully Pets blue dog birthday cookie is such a fun way to celebrate a pup’s special day. The packaging is adorable and really makes it feel like a treat meant for an occasion, not just an everyday snack. The cookie itself feels well made and sturdy, and my dog was very excited about it. I also liked that it didn’t have an overpowering smell and didn’t crumble everywhere when broken into pieces. It’s a great size for gifting or as a little birthday surprise, and it definitely made the moment feel more special. Overall, it’s a cute, thoughtful treat that’s perfect for celebrating a dog birthday and bringing a little extra joy to the day.
