55 lb Bumper Plates

Vulcan 55 lb Bumper Plates Description:

Vulcan Bumper Plates are built to endure the rigors of Olympic Weightlifting and CrossFit® workouts. Unlike lower-priced brands, our bumper plates are made of a harder and denser rubber compound, resulting in a much thinner profile that allows for more plates to fit on the bar.

Many competitors claim to have equivalent rubber hardness, but their 10 lb and 15 lb bumper plates often "waffle" easily when dropped. The typical bumper plate features a thin pressed steel insert that can detach over time with repeated drops. Our inserts are forged solid steel and anchored into the plate. We were the first to introduce this technology in 2011, and to this day, we have replaced fewer than a dozen bumper plates out of multiple tons sold.

When lifting our bumper plates, you'll immediately notice how snugly they fit together on the bar, along with the dead blow/low bounce effect they exhibit when dropped. This creates a distinct sound compared to the clanking and basketball-like rebounding typical of lesser brands.
