For Subaru Outback owners and SUV drivers, towing isn’t just a utility—it’s an extension of adventure. The CURT 13570 Class 3 Trailer Hitch emerges as a cornerstone for safe, efficient hauling, combining rugged durability with thoughtful engineering. Designed to handle up to 3,500 lbs of gross trailer weight and 350 lbs of tongue weight, this hitch transforms your vehicle into a versatile workhorse capable of towing trailers, transporting bikes, or carrying cargo. In this comprehensive guide, we’ll dissect every aspect of the CURT 13570, from its industrial-grade construction to real-world installation insights, ensuring you understand why it’s a top choice for drivers demanding reliability and performance.
Engineering Excellence: Built to Withstand the Toughest Challenges
The CURT 13570 is crafted from high-tensile carbon steel, a material chosen for its exceptional strength-to-weight ratio. Unlike cheaper alternatives that use thinner gauge steel, this hitch undergoes precision laser cutting and robotic welding to ensure structural integrity under heavy loads. The dual-coat finish—a fusion of rust-resistant liquid A-coat and durable black powder coat—provides unparalleled protection against corrosion, UV rays, and road debris. This coating isn’t merely cosmetic; it’s a critical defense layer, especially for drivers in coastal or snowy regions where salt accelerates rust.
The hitch’s 2-inch x 2-inch receiver is a universal gateway to versatility. Whether you’re attaching a bike rack, cargo carrier, or tow hook, this standardized size ensures compatibility with countless accessories. CURT’s commitment to safety is evident in its rigorous testing: Each hitch undergoes real-world simulations at their Detroit facility, adhering to SAE J684 standards for load distribution and stress resistance. This means the 13570 isn’t just strong—it’s intelligently engineered to distribute weight evenly, reducing strain on your vehicle’s frame.

Installation Demystified: Tackling the Process Like a Pro
Installing the CURT 13570 is a manageable DIY project, but it demands patience and preparation. The hitch bolts directly to your vehicle’s frame, requiring temporary removal of the exhaust system and minor modifications to heat shields. Here’s a step-by-step breakdown:
- Prep the Vehicle: Park on a flat surface, use jack stands or ramps for elevation, and disconnect the battery to avoid electrical issues.
- Lower the Exhaust: Remove rubber hangers supporting the muffler and mid-pipe. Support the exhaust with a jack stand to prevent strain on components.
- Modify Heat Shields: Trim or bend heat shields near the frame to accommodate the hitch. This prevents rattling and ensures a flush fit.
- Position the Hitch: Align the hitch with pre-drilled frame holes. CURT’s vehicle-specific design ensures bolt holes match perfectly.
- Secure with Hardware: Use provided bolts and washers to fasten the hitch. A torque wrench is essential—tighten to manufacturer specs (typically 55–65 ft-lbs).
- Reattach Exhaust: Rehang the exhaust system, ensuring no contact with the hitch to avoid vibrations.
Pro Tips:
- Two-Person Job: While solo installation is possible, an extra set of hands simplifies alignment.
- Wire Pulls: Use duct tape to guide bolts into tight spaces if the provided wire pulls are insufficient.
- Post-Install Check: Test drive slowly to detect rattles, then re-torque bolts after 50–100 miles.
One Subaru Outback owner shared: “Removing the mufflers saved me hours of frustration. The hitch fit like a glove, and the powder coat still looks pristine after two winters.”
Versatility Unleashed: Beyond Basic Towing
The CURT 13570’s 2-inch receiver isn’t just for trailers—it’s a portal to endless possibilities:
- Cargo Carriers: Haul camping gear, coolers, or luggage without sacrificing cabin space.
- Bike Racks: Transport up to four bikes securely, ideal for weekend adventures.
- Tow Hooks: Add recovery points for off-road excursions or roadside assistance.
- Snow Plows: Compatible with lightweight plows for winter maintenance (check vehicle capacity).
This adaptability makes the hitch indispensable for road trips, DIY moves, or seasonal tasks.
Safety and Durability: Engineering Peace of Mind
CURT’s adherence to SAE J684 standards means the 13570 isn’t just strong—it’s smartly designed. The hitch undergoes:
- Fatigue Testing: Simulating years of vibration and shock to identify weak points.
- Load Distribution Analysis: Ensuring stress spreads evenly across the frame, not just the attachment points.
- Corrosion Resistance Trials: Salt spray tests validate the dual-coat finish’s longevity.
The result? A hitch that withstands 10+ years of abuse, from gravel roads to highway speeds.
Real-World Performance: User Experiences and Applications
- Towing Trailers: A 2024 Outback owner towed a 3,000-lb camper through mountain passes with zero sway, crediting the hitch’s rigid construction.
- Urban Use: A city driver uses a cargo carrier for weekly farmers’ market hauls, praising the easy attachment system.
- Off-Road Readiness: Overlanders pair the hitch with recovery boards and shovels, leveraging its robust mounting points.
Maintenance Tips: Preserving Your Investment
- Rinse Regularly: Wash the hitch with water after exposure to salt or mud to prevent corrosion.
- Inspect Bolts: Check tightness every 3,000 miles or before heavy towing.
- Lubricate Receiver: Apply grease to the receiver tube to prevent seizing and ease accessory changes.
