BUGPACK forged flanged crankshaft for high-horsepower air-cooled VW engine builds — forged from 4340 chromoly steel with nitrided Type-IV main journals and Chevy rod journals. The 6-bolt, 6-pin flange eliminates flywheel-to-crank movement that costs power and durability at high RPM. Select your stroke from the dropdown.

Application

  • High-horsepower air-cooled VW engine builds requiring a forged crank
  • Builds spec'd for Chevy rod journals (2.000" small-block Chevy)
  • Type-IV main journal compatibility
  • Flange-style flywheel mounting (6-bolt, 6-pin)

Why a forged crank

Cast cranks fail at high RPM and high load. A forged 4340 chromoly crank, properly nitrided and balanced, is the foundation for any engine making real power. The Chevy journal allows use of a far wider range of high-end aftermarket rods (Carrillo, Eagle, Manley, Scat, etc.) than the OEM VW journal sizes permit — cost-effective compared to building around custom VW-journal rods.

Great Value
Size: 4 Panels, Color: Grey, Size: 4 Panels, Color: Grey
These are great value and ideal for a divider that needs to be moved or maneuvered a small distance on a regular basis. Assembly is quick with a drill (don't over-tighten). Fabric seems of good quality and the unit seems sturdy expecially when linked together.

Great value, perfect for our infant room!
Color: Black, Size: Standard - 4 Panel
Great product, sturdy design and easy to build! It is a fairly light weight item, which aids in the maneuverability of the divider. The color was as described and is dark enough to block the light from our sleeping infants! I do love that you are able to see through the slats and see the child sleeping- if you are looking for something with MORE privacy, this is not it. It has great coverage area and is dark and a wonderful value for the price, however, you are able to see through the areas where each panel connects!

Don’t waste your money or time!
Color: White, Size: Standard - 4 Panel
Don’t waste your money. The instructions make no sense and the metal poles are either sized wrong for the product or screw holes are incorrectly placed, but no two poles matched in size and placement making it impossible to put this together without the panels being warped. No matter how I tried to switch the poles to see if I had them wrong, they always turned out warped and incorrectly fit. I finally gave up and threw everything out - I wasted $50 on this junk and because I didn’t try to put it together immediately after I bought it, it is way too late for a refund. Lesson learned!

Sturdiness
Color: Black, Size: Standard - 4 Panel
Not so sturdy. It worked well for its intended job, but, it has to be secured to the floor for long term use.
