Buyer’s Guide: What to Consider
Choosing the right locking hubs comes down to your vehicle, driving style, and budget. This guide covers the key factors to consider, from manual versus auto to spline counts and build quality, so you can make an informed decision.
- Manual vs. Auto: Manual hubs require you to get out and turn a dial, offering full control and often more durability. Auto hubs engage when you shift into 4WD, which is convenient for daily driving but can be less reliable in extreme conditions.
- Spline Count: The spline count must match your axle. Common counts are 19, 30, and 35. Using the wrong spline count can cause poor fit or damage. Always check your vehicle's specifications before buying.
- Build Material: Look for metal construction, especially in the clutch and gears. Stainless steel or alloy parts resist corrosion and last longer. Plastic dials are common but may wear faster under heavy use.
- Vehicle Fitment: Ensure the hub is designed for your exact make, model, and year. Some hubs fit a range of vehicles, but others are specific. Double-check the OE part numbers to confirm compatibility.
- Intended Use: If you off-road frequently, manual hubs with metal construction are better. For daily driving and occasional light trails, auto hubs offer convenience. Consider your typical driving conditions before choosing.
Conclusion
Locking hubs are a small part that makes a big difference in your 4WD system. Whether you prefer the rugged simplicity of manual hubs like the WARN 20990 or the convenience of auto hubs like the FEXON, there is a set here for your truck. Consider your typical driving conditions and how much effort you want to put into engaging 4WD.
For serious off-roaders, the WARN 20990 or Mile Marker 549 are excellent choices. For daily drivers, the A-Premium auto hubs offer easy operation. Whichever you pick, a quality set of locking hubs will keep your truck ready for any terrain.
