Racers and hot rod builders, here's a simple but crucial part: hub seals. This Allstar Performance pack gives you 10 seals, perfect for doing a few cars or keeping spares. They're made for Wide 5 hubs, you know, the classic pattern. Their big claim is the low-drag design. Why does that matter? Less friction on the wheel bearings can mean a tiny bit more power makes it to the ground and less heat buildup in the bearings – every little bit helps on the track or strip. Their main job is to keep the grease packed neatly inside the hub and around your wheel bearings, and keep dirt and grime out. A failed seal lets grease leak out and junk get in, which is a fast track to a burned-up bearing and a bad day. These are a standard maintenance item for anyone running older-style spindles and hubs. Toss this 10-pack in your toolbox; you'll need them eventually.
