We got sick of not having better billet main caps available so we designed and had our own made!
Estimate delivery for the caps is November. The deal is you get a decent discount for helping us get some of our money back early so we can keep doing R&D!
There's a few things we wanted to address;
- Made out of a high grade 4140 which is preferred for Barra main caps. Costs more but it's ~45% stronger and not too hard. This is important as if the caps are harder than the block is becomes very difficult to get a good roundness and finish on the tunnel. The hardness also makes the caps brittle which is not ideal for that sort of part
- Fixed the offset tunnel found on other options which makes machining harder and cost more
- Fixed the depth and width of the bearing tang groove so that bearings aren't being pinched and distorted or twisted
- Made by a repetition style machinist with custom fixturing to ensure great dimensionality and consistency
- Clearly marked with a window to engrave the blank caps once assigned
