KMC Grenade Crawl Beadlock Wheel
The Grenade Crawl is a beadlock wheel from KMC offered in a broad range of sizes and bolt patterns. Choose Satin Black or Machined, in 17, 18 or 20 inch diameters.
With five bolt patterns and five size and offset options, it covers a lot of off-road builds. Beadlock wheels are for off-road use only. Browse more wheels to compare other styles before you decide. The wheel has 37 variants across finish, size and bolt pattern, so work through bolt pattern first, then size and offset. A wide 20x10 at -48mm sits further out than a 17x8.5 at 0mm, so check fender and suspension clearance before ordering.
Universal. Sizes: 17x8.5 0mm, 17x9 -38mm, 18x9 -24mm, 18x9 +10mm, 20x10 -48mm. Bolt patterns: 6x139.7, 8x165.1, 6x135, 5x127, 8x170. Finishes: Satin Black or Machined. Off-road use only.
