OUR ONLINE CHECKOUT is CLOSED and we are NOT accepting any NEW orders at this time.

We are still fulfilling and shipping previously submitted and/or delayed order requests (as product availability allows) UNTIL NOVEMBER 15th 2022.

But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items).

Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. But we continue to endeavor to answer email inquiries as best we can. And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. It is still UNCERTAIN, but we may re-open a substantially downsized version of our store again in the Spring of 2023.

We sincerely appreciate your patience, understanding during this period of restructuring and/or closing. And a huge thank you to all of you whose support and loyalty we have been the beneficiary of over the 23 years that we have worked diligently to support the information and parts needs of the aircooled VW community!

4340 Forged Chromoly Super Race Type 1 Crankshaft, 76mm Stroke, Type 1 Rod Journals, 003-4376VW
4340 Forged Chromoly Super Race Type 1 Crankshaft, 76mm Stroke, Type 1 Rod Journals, 003-4376VW
 
4340 Forged Chromoly Super Race Type 1 Crankshaft, 76mm Stroke, Type 1 Rod Journals, 003-4376VW is a fantastic medium stroker crankshaft for budget builders. Made from 4340 Forged Chromoly, You'd need well over 250hp to out-do this crankshaft! Made from 4340 Forged Chromoly, this will rev as fast as your connecting rods and pistons will allow! 4340 Cranks are a step above cast and 4140 chromoly, and are great for applications around and over 200hp! The 76mm stroke is an excellent choice for all engines with the "mid stroker" build. This crank works best when used with 5.5" Rods, and "B" Piston and Cylinder Sets. This is a new crankshaft, so both Main and Rod Journals are STANDARD.

Case Clearancing for a 78mm crankshaft is not a big deal, the bigger the bore the less clearancing you'll have! If you have a small bore, you may have some clearancing for the rod nuts, at the cylinder spigots, and a little bit at the roof of the case also.

Another method is a rod length change. The logic behind this combo is as follows. "B" Pistons are designed for 5.4" rods. Since you are using a 78mm crankshaft, that's a 4mm smaller stroke (1/2 at the top, and 1/2 at the bottom). 2mm = .080" lower piston at TDC. We use .100" LONGER rods to put the piston .020" higher than stock, very easy to shim for, and you may not need shims at all!

Be sure to check piston skirt to Crankshaft CW Clearance during assembly, but this is usually not a problem due to the 5.5" rods!

These cranks are a GREAT way to build an engine with more grunt ON A BUDGET!!!
