Finish Your Rear End Build With A Clean Professional Look

Sometimes it is the small details that really bring a build together, and this Wehrli 12 Bolt Rear Differential Cover Bolt Kit does exactly that. Instead of sticking with basic hardware, this upgrade gives your Powerstroke a clean and refined look that stands out the moment you take a closer look underneath. The stainless steel ARP fasteners not only look great, but they also offer the kind of strength you want when everything is buttoned up tight. Additionally, the 12-point design gives you a more precise and secure fastening surface compared to standard bolts. This is the kind of upgrade that makes sense when you have already invested in a quality differential cover and want everything to match that level of detail. The included washers complete the setup and help distribute load evenly across the cover. Over time, the corrosion-resistant finish keeps everything looking fresh even in harsh conditions. It is a simple upgrade that adds both confidence and a polished finishing touch to your truck.

Precision Hardware Upgrade Designed For Wehrli Differential Covers

This bolt kit is engineered specifically for use with Wehrli 12 bolt rear differential covers, including part number WCF100172, on 1998.5-2024 Ford F250 and F350 Super Duty trucks. Each kit includes 12 high-strength stainless steel ARP fasteners along with 12 matched stainless steel washers for consistent clamping and proper load distribution. The 12-point bolt head design allows for improved torque application and better tool engagement during installation. Furthermore, stainless steel construction provides excellent resistance to rust and corrosion, making it well suited for trucks that see tough weather or off-road conditions. This kit replaces the standard socket head cap screws typically included with differential covers, offering an upgrade in both strength and appearance. Fitment has been specifically selected for Wehrli components, so compatibility with factory or other aftermarket covers is not guaranteed. The hardware is carefully chosen to ensure proper fit and reliable performance when paired with the intended application. It is a focused upgrade for builders who want dependable fastening with a clean, uniform finish.
