Customer q:

Hello Tech support.

I need your support.

A friend of mine can't find a piston (H687CPA STD) for his BUICK 1995 RIVIERA 3.8L V6 Supercharged, VIN 1G4GD2214S4702639. His provider sent him one piston, but it has less height than the mounted piston on his car (62.7mm vs 53.2mm).

Please tell me which model and piston size is best for this car. Maybe there is a modern analogue of the piston H687CPA STD.


drivewheel = 2WD

engine = 3.8L V6 Supercharged

make = BUICK

model = RIVIERA

year = 1995


Thank you for giving Jegs the opportunity to assist you.

For engine VIN code 1 this H687 is the correct piston for this this should have a compression height of 1.3888".

Should you need further assistance please feel free to contact us.
