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.

• Feels like training with steel

• Protects floors like a bumper

• Reduces noise and vibration

• Offers unmatched durability and impact resistance

• Maintains tight tolerances and consistent geometry

With a 90 durometer rating, these plates are dense and firm. They protect your floors without the excessive rebound you get from traditional rubber bumpers.

KEY FEATURES

• Premium polyurethane enclosure for reduced noise and superior floor protection

• Ultra-thin profile allows more weight on the bar

• Olympic standard 2" center hole fits all Olympic bars
