Pistons take the actual explosion. Thousands of times a minute each one is fired down its bore and hauled back up the con rod, which is why a spare one on a desk always draws a look.

This mini is a piston on its con rod in stainless steel and alloy, with the crown, skirt and pin detail all modelled. Roughly 3 to 4cm with the ring and around 25g, in five finishes photographed individually.

Questions

Is the photo the exact finish I will get?

Yes. Every finish is photographed individually and the picture changes to match your selection.

Does the con rod move?

Treat it as a solid piece. The piston and rod are cast together with the detail modelled in.

How big is it?

Roughly 3 to 4cm long including the ring and around 25g, so it has heft without weighing your pocket down.

What is the delivery time?

Two weeks maximum, worldwide. Free in the UK, a flat 9 pounds everywhere else, tracked either way.

Piston and rod in one piece

Crown, skirt and the little pin detail are all there. The gunmetal finish looks like a used part in the best way.

Rainbow piston is the one

The oil slick colours over the machined shapes look brilliant. Heavy enough to feel proper on keys.

Sarah K· Norwich· 13 July 2026✓ Verified buyer

Good casting, edges crisp

Nice solid piece and the rod is straight. The crown edge is a little sharp when it is new, softens with pocket wear.

Gold piston gift

Got it for an engine builder and he clocked the con rod shape immediately. Photo matched the finish spot on.
