I got these for a "quickie makeover" on my rear differential, because the listing showed the bolts as being a (superior) Grade 8, and because of the smooth, chromed finish. Actually, neither of those apply.The bolts are not flush as in the photos, but more like generic hardware store hardware that's not nearly as pretty. Also, the markings on the bolt itself indicate they're Grade 5 bolts, a much less expensive alternative to the Grade 8 bolts I thought I was getting.The end result of my makeover was still an improvement, but there's no way these bolts are worth the money.

The 1 Set of 12 Grade 8 Hardened Differential Cover Bolts is a set of high-strength bolts designed specifically for use with various Dana and AMC differentials, including the Dana 30, 35, 44, AMC 20, and Chrysler 8.25. These bolts are compatible with Jeep models like CJ, YJ, TJ, JK, XJ, MJ, ZJ, WJ, WK, XK. Here’s a detailed review based on the product’s features and performance:Pros:High-Strength Grade 8 Bolts: Made from Grade 8 hardened steel, these bolts are built to handle the stresses of differential cover applications. Grade 8 is a high-strength material, making these bolts much more durable and resistant to shear or deformation compared to standard bolts. This is important when working with the differential, as it experiences significant pressure and torque.Corrosion-Resistant Coating: The bolts often come with a corrosion-resistant coating, which helps prevent rust and deterioration over time. This is especially important for bolts exposed to the harsh conditions of off-roading, where mud, water, and road salt can quickly cause other bolts to rust.Perfect Fit for Multiple Jeep Models: This set is designed for Jeep models, including CJ, YJ, TJ, JK, XJ, MJ, ZJ, WJ, WK, XK, as well as a variety of differentials such as Dana 30, 35, 44, AMC 20, and Chrysler 8.25. If you're working on one of these vehicles and need replacement or upgraded differential cover bolts, this set will fit properly without the need for modifications or special adapters.Complete Set of 12 Bolts: The set includes 12 bolts, which is enough for most differential covers. This ensures you have enough hardware to properly secure the cover without needing to purchase extra bolts separately. The complete set is convenient and helps save time and money.Easy Installation: Replacing or upgrading differential cover bolts is a simple task that doesn’t require advanced tools or mechanical expertise. These bolts are designed to be straightforward to install, making them an ideal choice for DIYers and professional mechanics alike.Cons:Not for Other Differential Models: These bolts are specifically designed for the Dana 30, 35, 44, AMC 20, and Chrysler 8.25 differentials, so they may not be compatible with other differential types or vehicles. If you're working with a different vehicle or differential, you’ll need to find a set that matches your specifications.May Require Proper Torque: As with any automotive fasteners, it’s essential to properly torque these bolts to avoid overtightening or under-tightening, which can cause leaks or damage. If you’re not familiar with torque specifications for your specific differential, it’s important to check the recommended values and ensure you don’t over-torque them.Standard Bolts May Be Sufficient for Light Use: While these Grade 8 hardened bolts provide excellent strength and durability, those using their Jeep for lighter duties or casual driving might not necessarily need such heavy-duty bolts. If you’re not doing extensive off-roading or towing, a standard bolt might suffice. However, if you’re into serious off-roading or need something extra robust, Grade 8 is the way to go.Overall:The 1 Set of 12 Grade 8 Hardened Differential Cover Bolts is a reliable, high-quality option for Jeep owners who need strong and durable bolts for their differential covers. Whether you’re doing a differential fluid change, replacing worn-out bolts, or upgrading your Jeep’s differential, these Grade 8 bolts offer the strength and corrosion resistance needed for both off-road and on-road performance. With a complete set of 12 bolts, installation is hassle-free and straightforward, making them ideal for DIY repairs. Just be sure to verify compatibility with your specific differential model before purchasing. If you’re looking for secure, long-lasting bolts for your differential cover, this set is a solid choice.
