Limitations: Some setups may require additional hardware for mounting brackets or brackets compatibility verification.
Buying Guide
Key considerations when choosing a tender spring kit for semi trucks:
- Load tolerance and line protection: Choose dual-tender kits for higher line mass or frequent multi-line routing. Consider single-tender options for simpler setups or constrained spaces.
- Material and corrosion resistance: Galvanized carbon steel springs endure harsh, outdoor environments better than bare steel. Look for anti-slip 3-in-1 holders and protective sleeves to guard cords and hoses.
- Mounting hardware and compatibility: Ensure the clamp holders and locking nuts fit your hose diameters and crossbar sizes. Check for adjustable or wide-design clamps if washers tend to slide.
- Length and routing: Longer springs (e.g., 20″) cover larger rigs but require more space. Shorter springs are more compact but may need more frequent adjustments.
- Maintenance and replacement: Look for straightforward installation with replaceable parts like clamps and holders. A sleeve or shield helps prevent tangling and wear over time.
