3.5in 3 Bolt Cover Plate

The 3.5in 3 Bolt Cover Plate from Quick Time Performance is an essential engine accessory for builders and enthusiasts working with modified powerplants. This precision-engineered component seals the bellhousing area where the engine block meets the transmission, protecting critical internal components from debris, oil spray, and environmental contamination. Whether you're upgrading a street engine, prepping a race build, or completing a custom engine swap, this cover plate ensures a professional installation and maintains engine cleanliness during operation and storage.

Designed with a 3.5-inch diameter opening and three-bolt mounting pattern, this cover plate integrates seamlessly with Quick Time Performance's modular bellhousing system. The three-point fastening design distributes load evenly and prevents vibration-induced loosening during high-RPM operation, a critical consideration for turbocharged, supercharged, or stroker engine builds. Measuring 5 x 1 x 5 inches and weighing just 1 pound, the compact design minimizes installation footprint while maintaining structural rigidity, making it ideal for tight engine bay configurations where space is at a premium.

This cover plate is essential for any serious engine builder integrating Quick Time Performance bellhousing solutions into LS-series engines, small-block Chevys, or other modern performance platforms. Installation requires basic hand tools and takes minutes—simply align the three bolt holes with your bellhousing flange and secure with appropriate fasteners. Mechanics and enthusiasts rely on this component as part of a complete powertrain assembly, ensuring proper alignment, reducing parasitic losses, and protecting long-term engine durability in both street and competition applications.
