Series 4 - Single Beadlock Wheel

Belak Industries Series 4 - Single Beadlock Wheel: Built for the Strip

The Belak Industries Series 4 - Single Beadlock Wheel is a three-piece drag wheel engineered for hard-launching cars that need to clamp a slick and keep it seated. The single outboard beadlock ring locks the tire bead in place under low pressure, and the exposed hardware around the lip gives it that unmistakable purpose-built drag look. Within the Belak lineup, the Series 4 stands apart with a clean spoke face and a milled treatment across the front.

Sizes and Fitments Stocked

The Series 4 comes in 17 and 18-inch diameters, with widths of 9.5, 10, 11 and 12 inches to cover both front runners and wide rear setups. Offsets in stock run +7, +20, +26, +39 and +58, so you can dial in poke or tuck depending on your chassis. Bolt patterns cover 5x112, 5x114.3, 6x114.3 and 6x135.

Concrete examples on the shelf include the 5x112 18x10 +7 and the wider 5x112 18x11 +20 for European platforms, the deep 5x114.3 18x12 +58, and for truck and six-lug builds the 6x135 17x9.5 +26. Browse everything in your pattern on the 5x112, 5x114.3 and 6x135 size pages.

Finish

The Series 4 is offered in a Milled finish, keeping the face bright and machined against the beadlock ring.

Price and Who It Suits

Pricing runs from $2,300 to $2,500 per wheel depending on size and bolt pattern. This is a serious drag and track piece for someone who wants a beadlock that holds a slick lap after lap, not a street-cruise wheel. If you want alternatives in the family, the Series 2 Single Beadlock shares the single-lock concept with a different face, the Series 2 Double Beadlock clamps both sides for the highest-power rears, the Series 2 Monoblock runs as a single-piece build, the Series 2 Non-Beadlock drops the lock ring for street use, and the Series 2 Single Beadlock Full Polished swaps the milled look for a polished finish. See the full range on the Belak Industries brand page.
