Classic Pontiac cars were big and heavy which requires more strength 

from your shock absorbers to maintain stability and control .

Our Extra Heavy Duty shocks utilize a 

50% bigger piston (1 3/8")

 and twice the oil capacity compared to a heavy duty shock.

The larger piston area spreads the load over a wider area which 

provides more control while maintaining a comfortable ride.

The larger oil capacity allows the shock to dissipate

 the heat faster and thus work more efficiently.

Choose hydraulic for period correct shock and ride:

 or

 pick gas charged for quicker response and a crisp feel.
