Ghost Strong
Ghost Roller J-Cup
Surplus Strength’s Stealth Spotters are a low-profile pair of safety spotter arms built around a gussetless, hand-welded American steel design that takes up dramatically less rack space than traditional spotter arms — reviewers consistently measure roughly 7” of upright space used, versus ~14” for a comparable design like Titan’s or Rogue’s Monster line. Each arm runs 27 3/16” long, offers 20”+ of flat catch depth plus a face-guard lip, and is built from a 3/8” welded steel mounting channel with a 1/4” laser-cut vertical face and a 1” stainless-steel mounting pin. Every contact point — barbell, upright, and the underside — is lined in UHMW to prevent metal-on-metal contact and protect knurling and rack finish alike. They mount to any 3”x3” rack with 1” holes on 2” spacing (concentric or offset patterns, 50mm spacing included) using just 3-4 holes instead of the 7-8 a conventional bracket needs, and each arm weighs about 25 lb. Sold in pairs for $550 direct from the manufacturer (Textured Black or Textured Red), with owners commonly reporting 10-14 day lead times. The compact bracket design means it relies on a rear pin for rotational stability — leaving it out introduces play, so it’s treated as a required step, not an optional one, across multiple independent reviews.

Rack attachments bolt or pin onto a power rack or squat stand to expand what it can do — J-cups and safety arms/straps (the essentials), plus dip bars, a landmine, a lat pulldown, weight-plate storage, roller J-cups, and more. They turn a rack into a whole gym.
An attachment must match your rack’s upright size (2x2, 2x3, or 3x3) and hole pattern/hardware (e.g. 5/8-in vs 1-in holes, Westside spacing). Attachments are usually series-specific — a Monster Lite J-cup won’t fit an Echo upright — so confirm the fit before buying.

The Stealth Spotters draw a rare convergence of independent praise – three YouTube reviewers, an in-depth blog review, and a 131-upvote r/homegym thread all lead with the same headline benefit: a roughly 7” upright footprint versus ~14” for a typical safety-arm design, freeing up holes for pulley systems, safety straps, and other rack attachments in space-constrained garages. Build quality is the standout dimension – 3/8” welded steel mounting channel, UHMW lining everywhere the arms touch a barbell or upright, and reviewers across six-plus months of use report clean welds and minimal wear. The weakest dimension is functionality: the gussetless design that makes the arms compact leans on a rear pin for rotational stability, and skipping that pin introduces noticeable play – a requirement, not an option. Value is the other soft spot: at $550+ per pair (versus roughly $351 for Rogue’s Monster Safety Spotter Arms 2.0), they carry a real premium, and buyers should expect a 10-14 day lead time.
