With spindles only, you can select parts that work with the bearings and hubs you use. If easy maintenance matters, look for grease zerk EZ Lube spindles, and confirm your hubs fit the spindles you choose. This setup helps you zero in on the fit you need without guesswork.
They can make routine greasing simpler. A grease zerk E-Z Lube version feeds grease through the spindle to the bearings, and hubs have fit perfectly on E-Z Lube spindles when the bearing sizes match. Some builders pack bearings, remove the zerk, and use a bearing buddy—pick the maintenance method you prefer.
Choose Spindles Only that accept the same bearings and seals as your current hubs. When the bearing sizes match, the hubs fit correctly on the spindles. If you want simpler maintenance, look for an E-Z Lube style with a grease zerk. After assembly, verify the hubs seat fully on the spindles before towing.
Match the spindle to your 3,500 pound hub and bearing set, and confirm brake compatibility. Install notes mention smooth installs on 3,500 pound axles and that 12" brakes are a big upgrade on heavier setups, so choose brake size to suit your weight. If you notice uneven tire wear later, inspect for bent components before replacing parts.
Yes, if the brake flange and rating match your setup. 12" electric brakes are used on heavier builds like 5,200 lb and 7,000 lb. Confirm the flange style, and make sure your hub and wheel bolt pattern match your wheels. If you're increasing capacity, check that your trailer frame and suspension are strengthened to handle the load.
