II. Product Details (PRODUCT DETAILS)

1. Wide-Range Adjustment + Multi-Vehicle Compatibility, Flexible and Unrestricted

(1) 24-41" Telescoping, Covering Most Wheelbases

• The tow bar length can be freely adjusted between 24" and 41" (ordinary fixed-length tow bars only fit a single wheelbase). Whether it is a short-wheelbase household SUV (e.g., Honda CR-V) towing a small camping trailer, or a long-wheelbase pickup truck (e.g., Ford F-150) towing a medium cargo trailer, the length can be adjusted to match precisely. No additional tow bars are needed, increasing adaptability by 80%;
• The adjustment structure adopts a precision rack + buckle locking design. Adjustment only requires pressing the buckle to stretch, and there is no risk of "automatic telescoping during driving" after locking (ordinary knob-type adjustments are prone to loosening), ensuring strong stability during high-speed towing.

(2) Universal Bolts + Flat Structure, Easy Installation

• 4 sets of Grade 8.8 high-strength bolts are included as standard, compatible with frame holes of most household SUVs and pickup trucks (hole diameter 8-10mm). No additional drilling on the frame is required (ordinary tow bars need customized bolts based on vehicle models, which is time-consuming and costly);
• The main body adopts a flat design of 4.45" × 0.98" × 0.59", fitting closely to the vehicle frame after installation without blocking chassis components (e.g., exhaust pipes, suspension systems), avoiding collisions with other parts on off-road or bumpy roads.

2. High-Strength Materials + Heavy-Load Protection, Safe and Rugged

(1) Alloy Steel Main Bar, Stable Load-Bearing

• The main bar is integrally drawn from high-strength alloy steel (ordinary tow bars are mostly carbon steel welded), with a tensile strength of 450MPa. When towing a full load of 5,000 LBS (approx. 2.3 tons), the main bar bending is ≤0.5mm, far exceeding the shortcoming of "carbon steel tow bars deforming at 4,000 LBS";
• In the test of towing a 2.2-ton medium RV, even on potholed roads, the tow bar shows no obvious vibration and bolts remain tight, ensuring long-distance towing safety.

(2) Multiple Protection Designs, Long Durability

• The black powder coating is cured at high temperature, with strong adhesion (no peeling in cross-cut tests). When used in coastal areas for 1 year, the coating does not peel and the base material shows no rust; after being contaminated with engine oil or sand, it can be cleaned with a high-pressure water gun, enabling convenient maintenance;
• The adjustment components are chrome-plated, with no oxidation when exposed to air for a long time. They remain smooth without jamming even after 500 adjustments (ordinary non-chromed components show rust and jamming after 100 adjustments), extending the overall service life.

3. Detail Optimization + Humanized Design, Enhanced User Experience

(1) Overload Warning + Anti-Slip Markings, Safer and More Intimate

• The main bar has a built-in overload warning structure: When the towing weight exceeds 5,500 LBS (110% of the rated load), the bar shows slight deformation (visible to the naked eye but not broken), reminding users to reduce the load or replace it with a tow bar of higher load capacity, avoiding safety accidents caused by "unaware overload and breakage";
• Clear length scales (24"/30"/35"/41") are printed on the adjustment buckle, allowing users to quickly find the appropriate length without repeated wheelbase measurement, increasing installation efficiency by 50%.

(2) Lightweight + Easy Storage, Portable and No Burden

• The overall weight is only 6.5kg (3kg lighter than carbon steel tow bars of the same load capacity), and installation can be completed with 2-person collaboration; when not in use, it can be disassembled into 3 sections (adjustment structure detachable) and stored in the corner of the car trunk, occupying only 0.1㎡ of space without affecting daily luggage storage.

IV. Frequently Asked Questions (FAQ)

Q1: There is a "squeaking" noise from the tow bar during towing after installation. What is the reason?

1. Check Adjustment Buckles: If the buckle is not fully locked (e.g., only half-pressed), the tow bar will shake slightly and produce noise — stop the vehicle, press the buckle until a "click" locking sound is heard, ensuring the buckle is fully embedded in the rack slot. The noise usually disappears;
2. Tighten Bolts: Insufficient bolt torque (<35N·m) during installation will cause bolts to loosen during driving and trigger noise — retighten the frame fixing bolts with a torque wrench according to the standard torque of 35-40N·m, and test towing after tightening;
3. Clean Adjustment Components: Dust and gravel accumulated in the adjustment components will cause friction noise — disassemble the adjustment structure, clean impurities between the rack and buckle with a brush, apply a small amount of silicone-based grease (do not use engine oil), and the noise will be eliminated after reassembly.

Q2: After long-term use, the tow bar adjustment becomes unsmooth or even stuck. How to handle it?

1. Rust Removal and Cleaning: Adjustment components are prone to rust after long-term exposure, causing jamming — gently polish rust on the rack and buckle with fine sandpaper (1000 grit) (avoid scratching the chrome layer), blow off rust powder with compressed air, and wipe clean with a cotton cloth dipped in neutral detergent;
2. Add Grease: Insufficient lubrication of adjustment components will increase friction resistance — apply special lithium-based grease (thickness 1-2mm) on the rack teeth and buckle contact surface, adjust repeatedly 3-5 times to ensure uniform lubrication, and the adjustment smoothness will be significantly improved;
3. Preventive Maintenance: Clean the adjustment components and replenish grease every 2 months. Especially after use in rainy or coastal environments, clean and prevent rust in a timely manner to avoid re-jamming.

Q3: How to confirm if my vehicle and trailer are compatible with YD37-002?

1. Confirm Trailer Ball Diameter: Measure the ball diameter compatible with the trailer coupler with a caliper; it must be 2" (approx. 50.8mm). If it is 1-7/8" or 2-5/16", replace with the corresponding ball or select another tow bar model;
2. Confirm Vehicle Frame Hole Position: Check if the tow vehicle frame has installation holes with a diameter of 8-10mm (standard for most household SUVs and pickup trucks). If the hole diameter does not match (e.g., 12mm), purchase compatible bolts (M10 to M8 adapters are available from the merchant) without re-drilling;
3. Confirm Trailer Weight: The full-load weight of the trailer must be ≤5,000 LBS (approx. 2,268kg). If the weight exceeds 2.3 tons (e.g., 2.5 tons), the overload warning will be triggered, and a tow bar with higher load capacity (e.g., 7,000 LBS class) is required;

• Example: A vehicle with 8mm frame holes, a 2" trailer ball, and a trailer weight of 2 tons is directly compatible with YD37-002.

Q4: During use, the tow bar suddenly triggers the overload warning (slight deformation of the bar). How to handle it?

1. Emergency Handling: Stop the vehicle immediately, disconnect the tow bar from the trailer, and prohibit further towing (even if the deformation is slight, the load-bearing capacity has decreased, and continued use may cause breakage);
2. Troubleshoot Overload Causes:
   - Check the actual weight of the trailer (whether it exceeds 5,000 LBS) by weighing it on a platform scale;
   - Confirm whether the goods are evenly placed (local overload may also trigger the warning). If the goods are too heavy, transport them in batches or adjust the placement position;
3. Subsequent Operations:
   - If the deformation is only slight (no breakage) and the overload cause is confirmed to be solvable (e.g., reducing the weight to within 2 tons), contact the merchant to test whether the tow bar is still usable (do not judge by yourself to avoid hidden dangers);
   - If the deformation is obvious or the safety cannot be confirmed, replace the tow bar directly and select a model with higher load capacity (e.g., 7,000 LBS class) to adapt to heavy-load needs.
