Starting at $25.95, AutoBuffy stocks 1 suspension strut brace bracket cover caps from URO for the Bmw X3. This plastic or metal cap clips over the strut brace bracket at the top of the strut tower, protecting the mounting hardware and brace ends from road grime, moisture, and corrosion. When it cracks or goes missing, exposed metal corrodes faster, leading to premature bracket and brace wear.
The main decision comes down to material, OE fit versus universal fit, and whether you need a single cap or a pair. Most Bmw X3 owners replacing a cracked or missing cap are best served by an OE-spec replacement that snaps onto the existing bracket without modification. If the bracket itself has corroded, look for a cap bundled with new hardware.
| Option | Best for | What you get |
|---|---|---|
| OE-replacement plastic cap | Direct, rattle-free fit on an undamaged original bracket | Exact-fit clip-on cover molded to match factory dimensions; typically sold as a pair |
| Heavy-duty ABS plastic cap | Higher-mileage vehicles in wet or salted-road climates | Thicker walls and UV-stabilized material for longer service life compared to standard OE-grade plastic |
| Metal (stamped steel or aluminum) cover cap | Performance or track builds where the strut brace sees higher stress | Greater crush resistance and corrosion resistance; may require minor fitting; adds minimal weight |
| Universal cap with adhesive or zip-tie retention | Budget repair or temporary fix when an exact-fit part is on back-order | Low-cost cover that protects the bracket from further moisture exposure; less secure than a clip-on fit |
Open the hood and locate the strut brace bracket at the top of each strut tower. Use a trim tool to pop off any remaining pieces of the old cap, then clean the bracket surface of rust or debris before pressing the new cap firmly into place until the retention clips engage. No lifting or wheel removal is needed, making this one of the simplest suspension-related jobs on the Bmw X3.
