PISTONS AJS TWIN 9:1 +040
A +040 oversize, 9:1 compression piston listed for the AJS twin motor, not a Triumph fitment.
This one falls outside what we usually handle. The description on file reads PISTONS AJS TWIN 9:1 +040, which is a piston for an AJS twin motor, oversized at +040 with a 9:1 compression ratio, not a Triumph part at all. We don't have any additional catalog appearances or notes on file to expand on it further.

Given it's an AJS part and not something we stock deep, treat this listing as informational rather than something we've verified fitment on ourselves. If you're chasing a piston for an AJS twin, give the shop a call and we'll see what we can do to help confirm before you commit to an order.
The part number R1035/040 also shows up as R1035.040 in some listings — same part, just written with a different separator.
