Custom Steel Crossmember Kit for Corvette C3 – Designed for 8L90 Transmission Swap
Upgrade your Corvette C3 with our custom-fabricated steel crossmember kit, purpose-built to fit the GM 8L90 transmission. This solution is ideal for builders looking to modernize their drivetrain while retaining accessibility and maximizing clearance.
🔧 Key Features:
Modular & Removable Design: This crossmember is fully bolt-in once installed, allowing the transmission to be removed at any time without needing to remove the engine or lift the body off the chassis. Designed with serviceability in mind.
Weld-On Flange System: The original crossmember must be cut, after which the included CTC Customs flanges are welded to the frame. This creates a strong, clean mounting point for the new removable crossmember.
High-Strength Steel Construction: Built to withstand the torque of modern drivetrains, this crossmember offers the strength and reliability needed for performance applications.
Clearance for 2.5” Oval Exhausts: Specifically designed to allow routing of dual 2.5” oval exhaust pipes under the car, providing enhanced ground clearance—ideal for lowered cars or track builds.
✅ For use with ENERGY SUSPENSION 31108G transmission mount (not included).
🛠 Installation Notes:
Cutting of the original crossmember and welding of flanges required.
Professional installation recommended.
Whether you’re doing a full restomod or just upgrading your transmission, this crossmember makes your 8L90 swap cleaner, smarter, and more future-proof.
