Dropped Crossmember Kit 2x3x60 Ladder Bar

The Competition Engineering Dropped Crossmember Kit 2x3x60 Ladder Bar (Model C3059) is a weld-on suspension component designed for drag racing and performance vehicles that require precise chassis geometry tuning. This 60-inch-wide ladder bar is engineered to lower the rear axle centerline by 3.5 inches, which reduces wheelbase compression during hard acceleration and improves weight transfer characteristics—critical for consistent traction off the line and minimizing wheel hop.

The kit features 2x3-inch mild steel tubing with 0.120-inch wall thickness, providing the structural rigidity needed to handle repeated launch forces without deflection or fatigue cracking. The dropped geometry allows builders to maintain a low center of gravity while keeping the rear suspension geometry neutral, which is essential in high-horsepower applications where rear-end angles directly affect launch angle and straight-line stability. As a complete weld-on kit, all components arrive ready to fabricate—no additional machining or modifications required. The natural steel finish requires surface preparation before welding and post-installation corrosion protection.

This crossmember is built for dedicated drag racing platforms, bracket racing cars, and street/strip vehicles where suspension tuning directly impacts elapsed times and consistency. Builders working with independent rear suspensions or converting classic vehicles to modern rear-end housings rely on dropped crossmembers to achieve the correct pinion angle and ride height without compromising drivability or longevity. The 19.45-pound component integrates with existing frame rails and requires competent welding equipment and fabrication experience to install safely.
