Frequently asked questions

What is the C26637-G piston assembly?
The C26637-G is a standard-size piston assembly for the Jaguar XK inline engine. The piston reciprocates in the cylinder bore, transmitting combustion pressure to the crankshaft through the connecting rod. It's made by Nural and sold individually.
When should I use standard-size pistons?
Standard-size pistons suit a cylinder block kept at its original bore dimensions, so they're for an engine that hasn't been rebored. If your block has been machined oversize during a rebuild, you'd need the matching oversize piston instead of the standard size.
How many of these pistons do I need?
These pistons are sold individually, so you need one per cylinder. A Jaguar XK is a straight-six, so a full engine typically takes six pistons. Order the quantity to match your engine and make sure every bore is at the same standard size.
Should I choose standard, +0.020in or +0.030in?
Choose the size that matches your cylinder block. This standard piston suits a block at its original bore. A block machined 0.020 inch over takes +0.020in pistons, and one bored 0.030 inch over takes +0.030in. Measure the bore before ordering.
