Thumper Thin Bumper Weight Plates

Name: Thumper Thin Bumper Weight Plates
Brand: Weight It Out
Rating: 4.75 (4 reviews)

The ‘Thumper’ Thin Bumper Weight Plates are Weight It Out’s ultra-thin bumper line, built around a solid steel core encased in a compression- molded polyurethane shell rather than the crumb rubber used in most bumpers. The 45 lb plate is only 1.3” thick – roughly half the width of a standard 45 lb bumper – letting lifters load far more weight onto a barbell, specialty bar, or plate-loaded machine sleeve before running out of room. A 90 durometer rating makes the plates dense and firm with noticeably less bounce than a typical rubber bumper, though reviewers note that firmness also means less floor and barbell protection than a true competition bumper on hard drops. Plates are sold in pairs across five weights (2.5-45 lb), backed by a lifetime warranty, and are made in the USA.

What is a Weight Plate?

What weight plates are

Weight plates load your barbell — but “plate” covers two very different tools. Bumper plates are rubber discs around a steel hub, all the same ~450mm diameter, built to be dropped from overhead without damaging your floor or bar; they’re the default for Olympic lifting and CrossFit. Iron/steel plates are denser and thinner per pound, cheaper, and quieter to load, but most aren’t made to be dropped — better for slow, controlled powerlifting-style work.

What actually matters

Bumper vs. iron. Buy bumpers if the bar might hit the floor; iron (or rubber-coated iron) for controlled lifts and compact loading.
Weight tolerance. How far a plate strays from its stated weight (±1% is tight, ±3% loose). It barely matters for general training but adds up if you chase a specific total — which is why serious lifters add small change / fractional plates.
Collar fit & bounce. The center hole should fit your bar’s sleeve snugly; rubber durometer (around 88 Shore A) controls how “dead” a dropped plate lands.
Coating & set composition. Virgin rubber holds up and smells less than recycled crumb rubber; plan a starting set (usually a pair each of 45/25/10/5 lb plus change plates) around the lifts you actually do.

Who it’s for

Every barbell gym needs plates. Most home lifters should start with a bumper set, then add iron, change, or specialty plates as a second purchase once they know what their training is missing.

The ‘Thumper’ Thin Bumper Weight Plates win reviewers over on raw functionality: a 45 lb plate barely thicker than a standard 15 lb bumper means a lot more weight fits on a barbell, specialty bar, or plate-loaded machine sleeve before running out of sleeve length. Build quality is the standout dimension – a solid steel core wrapped in a dense, 90-durometer polyurethane shell reads as a genuinely different (not novelty) design, with accurate weight (44.9 lb measured on a labeled 45 lb plate) and tight tolerances. Durability under impact is the weakest dimension: that same low-bounce firmness means less floor and barbell protection than a true competition bumper on hard or overhead drops, and reviewers specifically flag them as a poor fit for heavy overhead work.

+Functionality: 45 lb plate is only 1.3" thick -- about half the width of a standard 45 lb bumper -- so far more weight fits on a barbell or machine sleeve before running out of room (Garage Gym Reviews)
+Build quality: solid steel core wrapped in a compression-molded, 90-durometer polyurethane shell measured at 44.9 lb on a labeled 45 lb plate, within the advertised 1.5% tolerance (Garage Gym Reviews)
+Value: praised as a genuinely different, non-"novelty" design rather than a white-labeled rebrand of an existing plate (Garage Gym Reviews)
+Durability: backed by a lifetime warranty, cited by shreddeddad as justification for the premium price (shreddeddad.com)
+Versatility: dense, low-bounce polyurethane shell gives noticeably less bounce than typical rubber bumpers when dropped (shreddeddad.com)

−Durability: thin, dense construction offers less floor and barbell protection than a true competition bumper on hard drops -- reviewer specifically would not recommend them for heavy overhead work (Garage Gym Reviews)
−Value: premium pricing versus standard bumper plates -- roughly $260-270 for a 45 lb pair (Garage Gym Reviews, shreddeddad.com)
−Functionality: difficult to grip when lying flat on the floor (shreddeddad.com)
−Build quality: requires strong collars to prevent wobbling on the bar (shreddeddad.com)
−Versatility: only the 45 lb pair was available for hands-on review at launch, so lighter weights in the line (2.5-25 lb) are unverified by independent testers
