• Made for 1963–1987 Chevy C10 and C20 2WD frames
• Compatible with common LS and LT transmission bolt patterns
• Designed for direct bolt-on use without welding

How does this crossmember improve driveline stability and ride quality?

The crossmember’s heavy-duty steel construction and stable mounting points reduce drivetrain flex and movement under load, which can lower vibration and produce smoother gear engagement. A rigid, properly positioned support keeps the transmission aligned with the driveshaft, improving longevity of mounts and U-joints.

• Thick steel structure minimizes flex under torque
• Powder-coated finish resists corrosion and road wear
• Adjustability lets you fine-tune transmission position for proper driveshaft angle

What’s involved in installation—do I need special tools or welding?

Installation is intended to be straightforward: bolt the crossmember into place using the supplied hardware and secure the transmission to the mount. No welding is required, but typical automotive hand tools, a jack or lift, and basic mechanical experience make the job easier and safer.

• Includes necessary fasteners for mounting
• No welding or frame cutting required for standard installs
• Recommended: floor jack, jack stands, and torque wrench for safe alignment

What comes in the package and are instructions provided?

The kit contains one adjustable transmission crossmember and the hardware required for installation. Written instructions are not included, so having a repair manual or online installation guide for your vehicle and transmission is advisable.

• 1 x Adjustable transmission crossmember (powder-coated)
• Mounting bolts and necessary fasteners included
• No printed instructions; use a service manual or online resources

Who is this for: This crossmember suits classic Chevy owners restoring or upgrading C10/C20 trucks with LS or LT powerplants who want a durable, adjustable support without fabrication. It’s ideal for mechanics, hobbyists, and custom builders looking for a bolt-in, corrosion-resistant solution to stabilize the transmission and improve drivetrain alignment while retaining serviceability.
