Auto Power Roll Bars are essential safety components for various motorsports and performance driving activities. They provide crucial protection for drivers and passengers in the event of a rollover or collision. This article explores the different types of auto power roll bars available, their construction, and their applications.
Types of Auto Power Roll Bars
Auto power roll bars are categorized based on their design, intended use, and installation method. Common types include:
Street Roll Bar
Designed to enhance the aesthetics and provide a degree of protection in street-driven vehicles. They typically allow for rear seat retention and are constructed from 1.75″ x .120″ DOM mild steel tubing. Installation usually involves bolting the roll bar to the vehicle’s chassis.
Street-Sport Roll Bar
This type of roll bar caters to high-performance street cars. It often includes features like a bolt-in harness mount for easy installation of safety harnesses and a removable horizontal harness bar. Constructed from similar materials as the street roll bar, it offers enhanced safety for spirited driving. This allows for easy harness installation and access to the back seats.
Race Roll Bar
Engineered for competitive racing environments, including solo, autocross, and high-speed time trials. They feature a diagonal cross brace and often a harness mount tube. Autopower tailors the tube size and type to the specific vehicle and racing application. Race roll bars for heavier vehicles might use 2″ x .120″ ERW steel. Some race roll bars offer optional bolt-in diagonal and harness tubes for added versatility.
U-Weld Roll Bar
This option provides a cost-effective solution for those with welding skills. The cross brace and harness mount tubes are tacked in place, while the rear braces are not notched. The mounting pads can be welded or bolted to the car.
Bolt-In Roll Cage and U-Weld Roll Cage Kits
For comprehensive protection, bolt-in and weld-in roll cages are available. These provide a six-point mounting system and conform closely to the car’s interior. They are designed for various racing disciplines, including road racing, drag racing, and rally racing. Rally cage kits are specifically designed for rally racing and meet SCCA PRO RALLY competition requirements.
Auto Power Roll Bar Construction and Installation
Auto power roll bars are typically constructed from high-strength steel tubing, such as DOM (Drawn Over Mandrel) or ERW (Electric Resistance Welded) steel. DOM tubing is generally preferred for its superior strength and consistency. Most Autopower roll bars and cages are MIG welded for maximum strength and durability. Installation varies depending on the type of roll bar or cage. Bolt-in systems are designed for easier installation, while weld-in systems require professional welding expertise.
Conclusion
Choosing the right auto power roll bar depends on the intended use and the level of protection required. From street-driven vehicles to dedicated race cars, Autopower offers a wide range of options to enhance safety and performance. Consult with a qualified professional to determine the best solution for your specific needs. It is crucial to install the roll bar or cage before painting or coating to ensure proper fit and avoid damage.
