Series 4 Wheel - Single Beadlock Billet Outer Lip
Belak Industries Series 4 Wheel - Single Beadlock Billet Outer Lip: Track-Ready Three-Piece Drag Wheel
The Belak Industries Series 4 Wheel - Single Beadlock Billet Outer Lip is a three-piece drag and grip wheel built to lock a tire in place under hard launches. The single beadlock uses a billet outer lip that clamps the outer bead, so you can run low tire pressure without the bead walking off the rim. The face is a clean, spoked drag design, and the three-piece build lets Belak set specific widths and offsets for tight fender work. It sits in Belak's Series lineup as the beadlock-and-billet-lip option.

Finish
The Series 4 comes in a Milled finish, showing the machined face and billet outer lip against the wheel body.
Price and who it suits
Every size and bolt pattern is priced at $1,495 per wheel. This is a serious drag and track wheel for builds that need beadlock security at low pressure — anyone chasing traction on slicks or drag radials in a 15-inch package. If you want the beadlock without the billet outer lip, the Series 2 Single Beadlock is the sibling to look at, while the Series 2 Single Beadlock Billet carries the billet lip on the Series 2 face. Prefer a solid one-piece? The Series 2 Monoblock drops the beadlock entirely, and the Series 2 Non-Beadlock is a street-friendly alternative.
