Our 4-Link Solid Axle Rear Cradle Conversion for the CTS-V is finally here — the result of countless hours of design, testing, and fabrication. We built this system from the ground up to give CTS-V owners a reliable, high-performance rear-end solution that can handle serious power and repeat passes at the track.
This cradle replaces the heavy OEM IRS assembly with a fully bolt-on, lightweight chromoly setup that accepts Mustang-style rear suspension geometry. The design allows you to run an 8.8” or 9” Mustang housing, use adjustable torque boxes, and make easy suspension adjustments for different track conditions.
Built for strength, simplicity, and serviceability — this cradle is what the CTS-V rear end should’ve been from the start.
