Crafted from **ARP s proprietary 300M steel**, these bolts are heat-treated to an impressive **1,000,000 psi tensile strength**, ensuring they can withstand the brutal forces generated in top fuel drag racing, where ring gear loads can exceed 10,000 lb-in of torque. Each bolt features a **fine-threaded 7/16-20 thread** with a **1.000" shank diameter**, optimized for maximum clamp load distribution across the ring gear s mounting surface, preventing slippage, distortion, or catastrophic failure. The bolts are **nitrided for superior corrosion resistance**, making them ideal for high-humidity environments or repeated washdowns, while their **customized head design** with a **13/16" hex body and a 1.000" bolt circle** ensures proper alignment and torque application, reducing the risk of cross-threading or stripping. Engineered with **ARP s signature high-performance features**, including a **smooth, polished finish** for easy installation and a **precision-ground thread** for consistent torque retention, these bolts are a direct replacement for OEM components but far exceed their capabilities. Whether used in **top fuel dragsters, super stock cars, or high-performance street rods**, this bolt kit provides the critical structural integrity needed to handle the most demanding racing applications while maintaining durability over countless high-speed runs. Built to ARP s rigorous standards, this kit is a must-have for any serious racer looking to eliminate ring gear failure and maximize performance.
The **ARP 672036010836 Top Fuel Ring Gear Bolt Kit** is designed for high-performance applications, particularly in Ford and Strangemotor builds where extreme stress and torque are involved. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.
---
### **Pros**
1. **Superior Strength and Durability**
ARP bolts are forged from high-strength steel and heat-treated to extreme specifications, far exceeding OEM standards. These bolts are engineered to handle the immense loads generated in top fuel drag racing, where ring gear torque can exceed 10,000 lb-ft or more. Their high tensile strength and fatigue resistance make them ideal for applications where failure is not an option.
2. **Precision Threading and Fit**
ARP bolts are machined to exacting tolerances, ensuring a perfect fit with the ring gear and yoke. This minimizes the risk of stripping or misalignment, which can lead to catastrophic failure. The threads are also coated with a lubricious finish to prevent seizing, even under extreme heat and vibration.
3. **High-Temperature Performance**
The bolts are designed to maintain their strength and integrity under high-temperature conditions, which are common in drag racing engines. This prevents thermal expansion issues that could compromise bolt integrity or cause binding.
4. **Corrosion Resistance**
ARP bolts are often coated with a protective finish (such as black oxide or other proprietary treatments) that resists corrosion, which is critical in environments where engines are exposed to moisture, salt, or other corrosive agents.
5. **Warranty and Reliability**
ARP is a well-established brand with a reputation for quality and reliability in high-performance automotive applications. Their bolts come with a warranty, and they stand behind their products with customer support. This adds peace of mind for serious racers who cannot afford bolt failure.
6. **Compatibility with High-Performance Modifications**
The kit is specifically designed for Ford and Strangemotor builds, which often involve heavy-duty modifications like larger engines, superchargers, or nitrous systems. These bolts are engineered to support such modifications without compromising safety.
7. **Easy Installation and Maintenance**
While ARP bolts are high-performance, they are not overly complex to install. The kit includes all necessary hardware, and the bolts are designed to be straightforward to torque to specification. ARP also provides clear instructions and torque values, reducing the risk of improper installation.

### **Cons**
1. **Cost**
ARP bolts are significantly more expensive than OEM or aftermarket alternatives. For example, a set of ARP ring gear bolts can cost several hundred dollars, whereas OEM or generic aftermarket bolts might cost a fraction of that. This high cost may be prohibitive for hobbyists or those on a tight budget.
2. **Overkill for Mild Applications**
If you are not running a top fuel drag racing setup or a similarly extreme application, these bolts may be unnecessary. For street or mild racing applications, standard high-quality aftermarket bolts (such as those from ECI, JE, or even upgraded OEM bolts) may suffice without the premium price tag.
3. **Specialized Knowledge Required**
While ARP bolts are easy to install, using them effectively requires an understanding of proper torque values, bolt stretch, and the importance of preloading. Improper installation (e.g., overtightening or undertightening) can compromise the bolt s performance or lead to premature failure. This may necessitate consulting with a professional or experienced mechanic.
4. **Limited Availability**
ARP parts are not as widely available as OEM or mainstream aftermarket components. This could make it more difficult to find replacement bolts or service them in the future, especially in areas without specialized performance shops.
5. **Potential for Overengineering**
Some builders may argue that ARP bolts are "overkill" for their specific application, leading to unnecessary expense. For instance, if you are running a mild supercharged engine or a street rod, the additional strength of ARP bolts may not be fully utilized, making the investment less justifiable.

### **Conclusion**
The **ARP 672036010836 Top Fuel Ring Gear Bolt Kit** is one of the best options available for extreme high-performance applications, particularly in top fuel drag racing or similarly demanding setups. Its unmatched strength, durability, and reliability make it a critical component for builders who prioritize safety and performance above all else. However, the high cost and specialized nature of these bolts mean they are not suitable for every application or budget.
For most street or mild racing applications, there are more affordable alternatives that provide adequate strength without the premium price. ARP bolts are justified when the application involves extreme torque, high stress, or a need for absolute reliability in a life-or-death scenario.

### **Recommendation**
- **Buy the ARP kit if:**- You are building a top fuel drag racing engine or a similarly extreme high-performance setup.
- You are running a heavy-duty supercharger, nitrous system, or other modifications that generate extreme torque.
- You prioritize safety and reliability above cost and cannot compromise on bolt integrity.
- You are working with a professional builder or mechanic who understands the importance of proper bolt selection and installation.
- **Avoid the ARP kit if:**- You are on a tight budget and the application does not require extreme strength (e.g., street rod, mild supercharged engine, or light-duty racing).
- You are not comfortable with the cost or the need for specialized knowledge to install and maintain the bolts.
- You can find equally strong alternatives (e.g., ECI or JE high-performance bolts) that meet your needs at a lower cost.
For most builders, a middle-ground approach such as using **ECI or JE high-performance ring gear bolts** may offer a balance of strength, cost, and availability without the premium price of ARP. However, if you are pushing the absolute limits of performance and cannot afford any margin for error, the ARP kit is the safest choice available.
