Dazakoot 16" Double Tender Spring Kit for Trailer Lines — 2PCS with Protective Sleeve & No-Tool Aluminium Clasp

Dazakoot 2PCS 16" Double Tender Spring Kit is a heavy-duty suspension accessory that secures and protects trailer air and electrical lines by suspending them away from the road and chassis.

This 16-inch double tender spring assembly from Dazakoot is engineered to prevent cables and air hoses from dragging, chafing, or being exposed to road hazards. Built for fleet, owner-operators, and trailer service technicians, the kit replaces common OEM parts and helps maintain clean routing of lines under a wide range of operating conditions. The package includes two springs, a locking aluminum clasp, protective sleeves, and durable hanger brackets for quick, no-tool installation.

How does the tender spring protect my trailer lines during operation?

The spring acts as a shock-absorbing buffer between the suspension and the routed lines, keeping hoses and wires elevated and reducing contact with debris or the ground. Its galvanized carbon steel construction offers elasticity to absorb movement while the protective sleeve prevents abrasion and UV damage.

• Absorbs suspension travel to prevent tugging on fittings and connectors.
• Protective black sleeve stops abrasion from chafing and sunlight.
• Galvanized finish resists rust for long-term outdoor exposure.
• Rated to handle up to 30 lbs per spring for secure support.

What makes this Dazakoot kit easy to install and compatible with my rig?

Installation is designed to be simple and fast—no specialty tools required—using an aluminum locking clasp and heavy-duty hanger bracket that attach to common suspension rods and frames. The kit includes an extra spring tube and an additional hook so you can adapt the mount to different suspension rod diameters and trailer setups.

• No-tools aluminum locking clasp for fast connection and removal.
• Extra spring tube included for flexible routing options.
• Hanger bracket fits a range of suspension rod sizes with rubber cushioning.
• Works with standard 3-in-1 air line kits for semi trucks and trailers.

How durable is the tender spring kit in harsh road environments?

Durability is a focus: the core spring uses galvanized carbon steel for strength and corrosion resistance, while hanger clamps are formed from 304 stainless steel with rubber cushioning to resist rust and vibration wear. The result is a kit built to withstand continuous flexing, moisture, and road contaminants.

• Galvanized carbon steel spring maximizes lifespan and elasticity.
• 304 stainless steel hanger clamps resist corrosion and water damage.
• Rubber cushioning reduces metal-to-hose abrasion and vibration noise.
• Protective sleeve shields lines from UV and physical wear.

Can I replace OEM tender springs with this Dazakoot kit?

Yes. The Dazakoot 16" Double Tender Spring Kit is suitable as a replacement for several common part numbers and aftermarket assemblies, providing comparable function and fit with enhanced corrosion protection. Verify fitment against your vehicle’s suspension geometry before installation.

• Compatible replacements include Mytee 9420-2, Velvac 580070, and Tectran models.
• Choose which spring tube to use depending on hitch and trailer configuration.
• Check suspension rod diameter and clearance for optimal routing.
• Designed for semi-truck trailer air and electrical line protection.

Who is this for: The Dazakoot 16" Double Tender Spring Kit is aimed at professional truck mechanics, fleet maintenance teams, and owner-operators who need a reliable, corrosion-resistant solution for suspending air and electrical lines. It's ideal for anyone replacing worn tender springs, retrofitting older trailers, or upgrading to a more durable, easy-to-install assembly that reduces wear and the risk of line damage.
