CheeMuii 20" Double Tender Spring Kit with 3-in-1 Semi Truck Air Line Holder — Galvanized Spring & Stainless Steel Holder

CheeMuii's 20" Double Tender Spring Kit paired with the 3-in-1 air line holder secures and protects truck air hoses and power cords while adding durable, rust-resistant support on trailers and semi trucks.

This two-piece set combines a galvanized 20-inch double tender spring with a robust stainless-steel 3-in-1 holder so fleets and owner-operators can keep service lines organized, tensioned, and shielded from abrasion. Built for heavy-duty commercial use, the components replace common OEM parts and are designed to resist corrosion, reduce line wear, and simplify retraction and storage of air hoses and electrical leads.

How does the spring kit protect and manage air lines?

The 20" double tender spring stores and buffers air hoses and cables under tension, preventing slack that can snag or drag. Its galvanized carbon-steel construction maintains elasticity and toughness under repeated use while minimizing rust in harsh weather.

• 20-inch length for extended reach and smooth retraction
• Galvanized finish reduces corrosion on exposed springs
• High-tensile carbon steel for lasting elasticity under load
• Protective plastic sleeve prevents entanglement with hoses and cords

What makes the 3-in-1 air line holder reliable on trucks and trailers?

The holder is fabricated from widened stainless-steel and fitted with an anti-slip rubber pad so hoses and power cords stay put during transit. Wide, painted hooks and a thick carbon-steel hook core provide strong, stable bearing capacity and resist deformation.

• Three-channel design organizes multiple lines (air, electrical, power)
• Anti-slip rubber pad secures hoses on rough roads
• 2" widened hooks fit large diameter crossbars without slipping
• Galvanized/painted surfaces protect against rust and chipping

Can this kit replace common OEM parts and fit my vehicle?

Yes — the CheeMuii kit is intended as a direct fit or compatible replacement for many popular part numbers and works across trucks, semis, trailers, and tractors. Check measurements against your current assembly; the strengthened hooks and universal design accommodate most commercial vehicle crossbars and mounting points.

• Compatible with Tectran 9421-2 and similar models
• Replaces Automann 177.3007, Tramec Sloan 451748, and others
• Wide hooks and 9.5 mm thick carbon-steel hook for flexible mounting
• Designed for trucking environments: road vibration and weather exposure

Who is this for? Drivers, fleet maintenance technicians, and owner-operators who want a rugged, long-lasting solution for storing and protecting service lines will benefit most. If you need corrosion-resistant components that reduce line abrasion, simplify cable management, and swap into common OEM setups, this CheeMuii spring kit and holder offer a practical, heavy-duty upgrade for everyday fleet use.
