Ladder Bar Frame Rails w/Brackets

The Chassis Engineering Ladder Bar Frame Rails with Brackets (C/E3673) are a welded pair of rear frame rails designed for high-performance chassis fabrication and custom frame construction. Built from heavy-wall 2 x 3 x 0.083-inch steel tubing with integrated ladder bar brackets, these rails deliver the structural rigidity and precision geometry required for serious off-road, motorsport, and specialty vehicle builds where frame stiffness directly impacts handling and safety.

Each rail measures 83 inches in length and arrives as a matched pair weighing 44 pounds total. The ladder bar brackets are factory-welded in place, eliminating fitment guesswork and ensuring consistent suspension geometry across both sides of the frame. The 2 x 3-inch tube profile provides optimal strength-to-weight efficiency in rear chassis applications, while the 0.083-inch wall thickness maintains adequate material for welding and load distribution without excess weight. These rails ship in natural (uncoated) steel, allowing buyers to finish them according to their specific build requirements—whether that means powder coating, welding directly into an assembly, or integrating them into a larger frame structure.

Ladder bar frame rails serve the builder, fabricator, and motorsport enthusiast who demands precision components for rear suspension architecture. These rails are ideal for custom hot rod frames, off-road vehicle builds, drag racing chassis, and any application where controlled rear-axle location and vertical compliance are critical. The welded-in-place ladder bar brackets simplify alignment during frame assembly and reduce the fabrication time required to achieve suspension geometry targets.

Chassis Engineering is recognized in the hot rod and custom fabrication community for producing dimensionally accurate frame components that meet the exacting standards of professional frame builders. These ladder bar rails reflect that reputation—they are manufactured components, not generic tubing, with brackets pre-positioned to OEM or spec-sheet geometry. Verify compatibility with your specific frame design and suspension system before purchase.

All welding and fabrication should be performed by qualified personnel following applicable safety standards and local building codes.
