• Fitment: match the bolt to your vehicle's make, model, year, engine, and axle version; use your VIN for precise compatibility.
• Kit contents: some sets include nuts and washers — check the package contents before ordering to avoid missing parts during installation.
• Corrosion protection: zinc-coated or otherwise treated bolts last longer on Estonian roads, especially given winter salt exposure.
• Side and axle: verify whether the bolt is intended for front or rear axle and left or right side.
• OEM vs aftermarket: OEM bolts guarantee exact fit; quality aftermarket alternatives can be cost-effective — check the strength class.
