Meet the next generation of bumper plates. Our new ‘Thumper’ Thin Bumper Plates deliver the same proven engineering and performance as our blue line—now with a refined, all-black aesthetic. Designed for serious lifters who want maximum durability, minimal bounce, and the thinnest footprint in the industry.
WHY THESE PLATES ARE BETTER
These plates are built from solid steel cores encased in a compression-molded polyurethane shell—not basic rubber or crumb rubber.
This matters because basic rubber plates commonly deform, warp, chip, smell, and bounce excessively. Rubber also breaks down over time and often has inconsistent density and weight tolerances. Our polyurethane construction eliminates those issues entirely—delivering a cleaner, thinner, more durable plate with far less bounce, zero odor, tighter weight accuracy, and a finish that won’t shed or leave residue on your floors or equipment.
