3rd Gen F-Body LS Transmission Crossmember for 4L60E Swap
If you are swapping an LS engine into a 1982–1992 Camaro or Firebird, the 3rd Gen F-Body Crossmember (Only) 4L60E removes uncertainty around transmission placement. Designed to align with factory chassis mounts, this transmission crossmember holds the 4L60E in the correct position without any trimming or fabrication. It includes all necessary brackets and fasteners for a straightforward bolt on installation that keeps the driveline steady under load. With heavy steel construction matching the original frame geometry, this component delivers reliable support whether you’re tackling spirited road use or daily driving.
Precision Fit for Third Generation Camaro and Firebird
The crossmember is engineered to match the exact undercarriage geometry of 1982 to 1992 Camaro and Pontiac Firebird frames. By aligning to factory mounting points, it maintains proper driveshaft angle and reduces vibration that can lead to premature wear. This precision fit eliminates the need for trial and error when locating the 4L60E under the frame rail, ensuring consistent operation under heavy load. Enthusiasts benefit from a component that integrates seamlessly with the original chassis, preserving handling characteristics and drivetrain stability.
Durable Steel Design for Torque Support
Constructed from thick gauge steel, this crossmember resists flex and fatigue under high performance use. Critical weld joints are placed at stress concentration zones to deliver a rigid support structure for the 4L60E transmission and LS powertrain. The robust assembly minimizes chassis twist during hard acceleration, protecting mounting points and preventing misalignment over time. A corrosion resistant finish extends component life, even in harsh road conditions or seasonal exposure.
Simplified Bolt On Installation Process
All necessary brackets and hardware are included for a straightforward bolt on installation that requires no cutting or welding. Factory thread patterns and frame holes match the crossmember to the chassis, allowing you to secure the 4L60E in place using standard hand tools. This approach reduces labor time and eliminates the need for specialized equipment, making it accessible for both professional shops and home garages. Clear alignment guides ensure the transmission sits in the correct position from the start, streamlining the swap process.
Optimized LS Engine and 4L60E Transmission Integration
Specifically designed for LS engine conversions with the 4L60E transmission, this crossmember provides the ideal mounting location to balance weight distribution and maintain clearance for exhaust and suspension components. By positioning the transmission correctly, it preserves driveline alignment and prevents binding or noise under load. The result is a reliable connection between the motor and driveshaft that can handle increased torque and power output. This tailored solution simplifies complex engine swaps and delivers confidence in performance.
