• Wheel lug nuts must engage with studs for 10 full turns for safety - if lug nuts cannot reach 10 turns before full torque, discontinue use
• Mishimoto recommends an alignment after installation due to altered track width
• Corrosion should be removed from the hub before installing - excessive corrosion may prevent the spacer from fully seating

Product Description

The Borne Off-Road BNWS-002-381BK Wheel Spacers add 38.1mm (1.50 inches) of track width per side to your Ford F-250 Super Duty, F-350 Super Duty, or Excursion. Built specifically for the 8x170 bolt pattern used on Ford heavy-duty trucks from 2003 and up, these spacers deliver a direct-fit, hub-centric solution forged from 6061-T6 aluminum - a material that provides an optimal balance of high strength and lightweight construction for demanding heavy-duty applications. Whether you're looking to create brake clearance, prevent tire rub with wider tires, achieve a more aggressive stance, or improve stability while towing, the 38.1mm thickness offers a substantial track width increase that transforms the truck's appearance and handling characteristics.

The hub-centric design is central to the performance and safety of these spacers. Rather than relying solely on the studs to center the wheel, the 125mm center bore provides a direct extension of the axle hub, ensuring the wheel is precisely centered and eliminating vibration at highway speeds and under heavy loads. High-strength grade-12.9 steel studs come pre-installed in each spacer, and the included grade-12.9 lug nuts complete the mounting system for a secure, reliable connection. Every spacer is precision CNC-machined to exact tolerances for a true hub-centric fit with zero play. The durable black anodized finish protects against corrosion from road salt, moisture, and trail exposure.

Installation requires no drilling and can be completed with basic hand tools. These spacers fit SRW (Single Rear Wheel) F-250 and F-350 models only - they are not compatible with dually (DRW) configurations. Before installation, remove any hub corrosion to ensure the spacer seats fully, and verify that stock studs do not contact the back of the wheel - trimming may be required for clearance. Mishimoto recommends a wheel alignment after installation due to the altered track width. Additional thicknesses from 25mm to 50mm and a blue anodized finish are available in the BNWS-002 lineup. Every pair is backed by Mishimoto's Lifetime Warranty.
