NOTICE

Supply of many sought after parts is limited. Covid ripple-effect economic disruptions have hampered our company's ability to restock items reliably. We are doing what we can to recover from the changes to our industry and the effects they have had on our business, but currently a lot of shipments are delayed and our response time to emails are slow (we are severely short-staffed).


Please do NOT email to inquire for stock status. Instead, to get stock status, place an order request, and the items will ship if they are in-stock, OR we will post an itemized stock status for delayed items typically within 2-3 business days.

Placing an order request adds you to the reservation waitlist for out of stock items. We work diligently to source and fulfill backordered items as best we can -- backorders with unreliable restock ETAs are VERY frustrating for us as well. You can trust that even if we can't reply to your email, we ARE working on it and will contact you when we have any updated news to share. And of course, you can also email to cancel un-shipped/un-paid items at any time as long as they are not special order or made/machined-to-order.


Please only continue if you are prepared to be PATIENT. Your requested items might be significantly delayed by supplier-level backorder timeframes, and we usually aren't given reliable ETA information.

Thank you for your continued support and understanding.

Barrel Shims (aka Barrel Spacers, Cylinder Shims), 90.5/92mm, Type 1 Based Engines, Set of 4


 
Barrel Shims (aka Barrel Spacers, Cylinder Shims), 90.5/92mm, Type 1 Based Engines, Set of 4 are used to adjust the VW Engine's Deck Height for proper compression and combustion.

At ACN we feel that optimum deck height is between 040-.060", but the engine's compression ratio must also match the cam you are using.
