Round Chromoly Chassis Tube, 1-1/2 x 0.095 Inch, 3 Foot Length
This 1-1/2″ chromoly tube features a 0.095″ wall, offering robust performance for chassis construction and minor repairs. The 3′ length is ideal for shorter segments, supports, and mounting points. It is designed for easy fabrication with standard tubing tools and provides a solid balance of strength and weight. Suitable for automotive and hot-rodding projects where chromoly’s superior ductility and impact resistance matter.
Round Chromoly Chassis Tube, 1-1/2 x 0.095 Inch, 7 Foot Length
This 7′ chromoly tube mirrors the 3′ option but extends the reach for longer frame sections and mounting frameworks. With a 0.095″ wall, it provides strong resistance to bending while remaining workable with common tubing equipment. Ideal for home fabrication projects, race cars, and off-road builds requiring extended runs of chromoly tubing. The long length reduces joins and increases overall frame integrity.
Allstar Chrome Moly Round Tubing 1-1/2in x .083in x 4ft
With a slightly thinner wall than the typical .095″ options, this 4′ chromoly tube offers flexibility for less demanding structural sections while maintaining chromoly’s favorable strength-to-weight ratio. The .083″ wall makes it a viable choice for smaller braces, door bars, or light-duty chassis components. Its 4′ length is convenient for mid-length frame segments in hobbyist builds or repairs requiring moderate strength and good formability.
Allstar Chrome Moly Round Tubing 1-1/2in x .095in x 7.5ft
This 7.5′ tube combines a robust 0.095″ wall with a convenient length for longer sections and continuous frame members. It is well-suited for race car chassis rails, roll cages, and structural components where consistent diameters are required. The longer length minimizes splices, aiding in stronger, cleaner builds with fewer joints. As with other chromoly tubes, it requires proper welding techniques and post-bend support to preserve strength.
Allstar Chrome Moly Round Tubing 1-1/2in x .065in x 7.5ft
This 7.5′ chromoly tube with a thinner wall of .065″ offers enhanced flexibility and lighter weight. It is useful for intricate chassis components, light-duty brackets, or non-load-bearing frame sections where precise bending is essential. Care should be taken to ensure wall integrity is maintained during fabrication, and welding should be performed by experienced personnel to avoid compromising strength.
Allstar Performance Chrome Moly Round Tubing 1-1/2in x .095in x 4ft
This 4′ length of 1-1/2″ chromoly with a .095″ wall delivers reliable performance for mid-length frame sections and mounting points. The tube’s temper and strength characteristics support high-stress zones while remaining workable for basic cuts and welds. It serves well in racing chassis, roll bars, or custom fabrication projects where durability is essential.
Allstar Performance Mild Steel Round Tubing 1-1/2in x .120in 7.5ft
Note: This option is mild steel rather than chromoly, but it is listed among tubing options of similar diameter for comparison. It uses a thicker wall at 0.120″ and provides high strength for budget builds where chromoly is not required. If chromoly is a priority, this should be considered only for non-critical sections to maintain overall safety and performance standards.
Buying Guide: Key Purchase Considerations
When selecting 1.5″ chromoly tubing, consider: diameter consistency and wall thickness, which impact strength and weight; grade and alloy composition, affecting weldability and ductility; tube length to minimize joints and speed fabrication; compatibility with welding methods (MIG/TIG) and heat input; project requirements, including load paths, mounting points, and safety margins; and handling and storage, as chromoly can be sensitive to bending and scoring. Compare all-weld vs. bolted connections, and plan for future modifications. For longer frames, heavier walls (.095″) provide rigidity, while lighter options (.049″–.083″) reduce weight but require careful design. Ensure compliance with applicable safety standards for automotive and racing applications.
Additional Comparisons
- Wall thickness: .049″ to .095″ options balance weight and strength; thicker walls offer higher stiffness but add weight.
- Length: longer tubes reduce joints but can complicate handling and bending; shorter lengths are easier to maneuver in tight spaces.
- Brand variance: Allstar and Speedway Motors provide multiple wall options; verify the exact spec before purchasing to match your build plan.
- Welding requirements: chromoly requires precise welding and post-weld heat treatment depending on grade; ensure your welder has chromoly experience.
- Durability considerations: for high-stress applications like roll cages, prioritize .095″ wall with high-quality chromoly grade; for interior braces, lighter walls may suffice.
