Buying advice

When choosing a differential kit, consider your vehicle's axle type and intended use (daily driving, off-road, or performance). Selectable lockers offer best control but are costly and require installation; automatic lockers are simpler but may cause on-road noise. Limited-slip diffs are great for mixed use. Check compatibility with your vehicle and budget for additional parts like ring and pinion if needed.
