J-Bend Mild Steel 1.750 x 4in Radius 16 Gauge

The J-Bend Mild Steel 1.750 x 4in Radius 16 Gauge from Hooker is a precision exhaust tube bend designed for custom headers, intake manifolds, and primary exhaust piping in street and performance engine builds. This component addresses the challenge of routing tubing around engine bay obstacles while ensuring smooth flow characteristics. It is ideal for fabricators and engine builders looking to enhance performance in their projects.

Constructed from mild steel, which is a standard material for high-heat exhaust work, this j-bend features a tube stock measuring 1.750 inches in outside diameter with a 4-inch radius bend. The 16-gauge wall thickness provides a balance of weldability and durability, making it suitable for street applications and moderate boost conditions. Hooker's precision bending ensures consistent geometry, which is critical for port-matching to cylinder heads.

This j-bend is particularly beneficial for those working on LS, small-block Chevy, and mid-range displacement builds. Its design minimizes flow separation and maintains pressure dynamics, essential for header scavenging and intake runner efficiency. Whether upgrading a factory header or building a competition intake manifold, this product is a valuable addition to any performance engine project.
