ST Guitar Tremolo Bridge 52.5mm

Replacing a worn or mismatched Strat-style tremolo bridge can turn into a frustrating fit problem: the spacing may look close, but the mounting holes still have to line up. This 52.5mm ST bridge set is intended for many modern Squier Strat and Mexico Fender Stratocaster-style guitars, as well as American Standard-style ST models. It includes a push-in tremolo arm and mounting accessories, so it’s aimed at players who want a replacement set rather than a bridge alone. The key decision is whether your guitar’s existing layout matches its measurements.

Where it shines

The useful detail here is the combination of stated string spacing and mounting-screw spacing, not simply the vintage-style look. String spacing is 2-1/16 inches (52.5mm), while the mounting screw spacing is listed as 2-1/16 inches (53mm). That makes this a more considered purchase than choosing a bridge by appearance, especially if you’re replacing an existing unit and can compare its layout before ordering.

For example, if the current bridge on your Strat-style guitar is worn or you’re assembling a replacement setup, you can compare the string spacing and screw positions with the guitar, then judge whether this set is a plausible match. It’s a great fit if you want a complete tremolo bridge set with a push-in arm for a compatible ST-style guitar. If you prioritize a quick visual upgrade, the chrome finish and classic design may appeal, if you prefer a no-fit-risk replacement, buying only after confirming the body’s mounting layout is the more sensible route. The listing itself advises checking both the mounting holes and the space allowed by the pickguard.

Highlights

The bridge is made from solid zinc alloy and is described with a chrome finish. The included push-in tremolo arm is a practical part of the package for players who use a tremolo bar, if you don’t use one, that feature may matter less than getting the bridge dimensions right. Mounting accessories are included, but the product details don’t specify exactly which individual pieces are in the set, so don’t assume it includes every part needed for every guitar or setup.

The compatibility wording is broad rather than universal: it names many modern Squier Strat and Mexico Fender Stratocaster models, plus American Standard-style ST bridges. That’s helpful as a starting point, but the guitar’s actual hole pattern remains the deciding factor. On the spec sheet, the listed mounting spacing is 53mm, while the string spacing is 52.5mm, keep those as separate measurements when comparing your current bridge rather than treating them as interchangeable.

Best use cases

This set makes most sense for a player replacing a tremolo bridge on a Strat-style guitar who can check the existing measurements first and wants the arm and mounting accessories in the same package. It may also suit a parts-upgrade project where a classic ST-style design is the goal, provided the guitar’s routing and mounting points match. It’s not for you if you need a bridge guaranteed to fit an unmeasured guitar, or if your instrument uses a different mounting arrangement. The stated fit covers particular Strat-style families, not every electric guitar.

Is it worth it?

Consider it when you have a compatible ST-style guitar, want a chrome-finish replacement with a push-in arm, and can verify the mounting layout before committing. The included pieces may be more convenient than sourcing a bridge and arm separately, especially for a straightforward replacement. The trade-off is that the listing does not establish universal fit or detail every included mounting part. If you can’t compare your guitar’s holes and pickguard clearance with the stated dimensions, a model-specific replacement is a safer buying approach than relying on the family name alone.
