10-031-20 Knuckle Performance, Super Narrow triple tree kit. 39mm

The Bare Knuckle Performance Super Narrow triple tree kit for 39mm fork tubes is the original choice for builders wanting a slimmed-down front end. These gloss black powder-coated trees are 1 inch narrower than a stock Narrow Glide, with a 6-inch center-to-center tube distance. The kit includes everything you need for the swap: a steering stem, tapered flange washer, ARP stem bolt, and a dedicated 1-inch diameter stainless steel wheel axle. The axle is crafted from 17-4 series polished stainless steel for maximum strength and a lasting shine. The trees feature integral steering stops and are drilled for standard 3-1/2 inch riser spacing and a 3/8-inch headlight mount. It is a comprehensive universal kit that delivers a high-end, custom aesthetic with rock-solid performance.
