1275cc Low compression - low drag slipper type piston in standard size for modern day compression ratios and unleaded fuel.  Typically installation will result in a minimum 8.8:1 compression ratio but on some pre-1984 Metro versions it was higher.  Current pistons differ from the 60s originals, improved with a "low drag" slipper skirt design and a shorter lighter wrist pin.

Wrist pin height is 1.4689", crown has 8cc dish, and they have two 1.5mm compression rings and a 4mm oil ring. From the top ring to crown these measure about 7mm and the high compession P21253 piston have 10mm gap from top ring groove to crown. Sold each - 4 per engine required.

Now Nural stamped 87-521711-00. AE Hepolite is now owned by Federal Mogul and trademarked "Nural".

Piston Fact File
Created: January 30, 2000
Over the years, there have probably been a dozen "stock" 1275 pistons. Currently, three different designs are available from AE/Hepolite as "stock" replacements. All have an 8.4cc dished top, but compression ratios are carried by changing pin height (Pin height is the distance from the top of the piston to the center of the wrist pin- see dimension "A" shown here).
