What does 'A/G-Body' mean?

GM A-body cars were produced from 1964-1981, and G-body cars from 1982-1988. These cars share similar suspension mounting points, so this kit fits both. Common models include the Chevelle, Malibu, Grand Prix, and Regal.

What is the benefit of being able to re-valve the shocks?

Re-valving allows you to fine-tune the shock's damping characteristics to match your driving style, track conditions, or vehicle setup. By changing the valve packs, you can adjust how the shock responds to bumps and dips, improving handling and control.

What does '12in x 175lbs/in' mean?

This refers to the spring's length and stiffness. 12 inches is the free length of the spring. 175 lbs/in means it takes 175 pounds of force to compress the spring one inch.
