Reese Strait-Line Weight Distribution Hitch | 66074 | 12K GTW No Shank

Tow your travel trailer with maximum stability, control, and safety with the Reese 66074 Strait-Line Weight Distribution Hitch with Dual-Cam Sway Control. This premium weight distribution system evenly spreads your trailer's tongue weight across all axles, levels your ride, and actively prevents trailer sway before it begins — letting you tow to the maximum capacity of your hitch with the confidence that comes from professional-grade towing hardware. Rated for 12,000 lbs gross towing weight and 600-1,200 lbs tongue weight.

Why a Weight Distribution Hitch Matters

If you tow a travel trailer near the maximum capacity of your tow vehicle without a weight distribution system, you'll experience several real problems:

• The rear of your tow vehicle sags, lifting the front wheels and reducing steering control
• Your headlights point upward into the sky instead of illuminating the road ahead
• Uneven tire wear on both your tow vehicle and trailer
• Reduced control over steering the entire rig
• You can't safely tow to the max capacity rated by your hitch

The 66074 solves all of these by transferring tongue weight from the rear axle of the tow vehicle out to the front axle of the tow vehicle AND back to the trailer axles — restoring level ride height and proper weight distribution across the entire rig.

Dual-Cam Active Sway Control — Prevents Sway Before It Starts

The standout feature of the Reese Strait-Line system is its dual-cam sway control — a significant improvement over traditional friction-style sway controls that only react AFTER sway has already begun:

• Straight-line driving: The cams lock in place and apply consistent pressure to both sides — holding the trailer steady against crosswinds and passing trucks
• Cornering: The cams automatically unlock and slide to allow controlled, full-radius turns with no fighting the wheel
• Sudden swerving: The cams give to accommodate the movement while still actively working to return the trailer to a straight-line angle — maintaining control during emergency maneuvers

The system is self-adjusting and self-centering — no manual intervention required during operation.

Trunnion Spring Bars — Hot Rolled and Tapered

The Strait-Line uses trunnion-style spring bars with hot-rolled, tapered construction for superior strength and flexibility:

• Bars flex appropriately over uneven terrain for a controlled, even ride
• Rounded, hooked ends work with the active dual-cam system
• Tapered design distributes force progressively rather than abruptly
• Hot-rolled steel construction for durability over years of use

Clean A-Frame Installation

Unlike some weight distribution systems that require platforms and U-bolts that interfere with trailer-mounted equipment, the 66074 uses a cleaner installation approach:

• Sway control bolts onto the A-frame trailer tongue
• Attaches to lift brackets via chains
• No U-bolts or platforms to interfere with frame-mounted gas tanks, toolboxes, or generators

Serrated Washers — Easy Head Adjustment

The 66074 uses an exterior serrated washer system instead of the traditional pin-and-washer method — meaning you can adjust the tilt of the weight distribution head without disassembling the entire head:

• Loosen, adjust, and tighten a single washer and nut on either side
• No more piling on washers with a difficult-to-access pin
• Dial in tension precisely for your specific trailer and load

Raised Hitch Ball Platform Built In

The head includes a raised platform forged into the head itself — eliminating the need for a separate raised hitch ball. One less component to source and fit.

Specifications and Capacity

• Gross Towing Weight (GTW): 12,000 lbs
• Tongue Weight Range: 600 lbs – 1,200 lbs
• Fits: 2" × 2" and 2-1/2" × 2-1/2" trailer hitch receivers rated for weight-distribution systems
• Lift-bracket positioning: Mount approximately 30" back from hitch ball
• Trailer frame space required: Approximately 5-1/2" along the trailer frame
• Maximum trailer frame width: 2-1/2" (will NOT fit wider frames)

Selecting the Right Weight Distribution System — Think "Goldilocks"

One of the most common mistakes RVers make when buying a weight distribution hitch is going too big. The right system isn't the highest-capacity one — it's the right-sized one for YOUR tongue weight:

• Overbuilt: Creates a rigid, harsh ride with a bouncing trailer
• Underbuilt: Can't distribute weight properly — virtually useless
• Just right: Distributes weight evenly without over-stiffening the connection

Calculate your needs: Trailer tongue weight + Cargo behind tow vehicle's rear axle = Combined tongue weight. The 66074's 600-1,200 lbs tongue weight range covers most travel trailer applications, but make sure your specific combined tongue weight falls within that range before ordering.

Need Less Capacity? Consider the 66021

If your tongue weight is closer to the 600-800 lbs range and you primarily tow in calmer conditions where active sway control isn't critical, the Reese 66021 Weight Distribution Kit is the smaller-capacity option in the Reese line — 8,000 lbs GTW with 800 lbs max tongue weight. Note: the 66021 does NOT include sway control (this 66074 does), so if you tow in windy conditions or have a sway-prone trailer, stick with the 66074.

⚠️ Important Compatibility Limitations

• Cannot be used with surge-type trailer brakes
• Designed for Class III and Class IV hitches only
• Should NOT be used with aluminum trailer frames
• Will NOT fit trailer frames wider than 2-1/2"

Verify all of the above against your specific setup before ordering.

What's Included

• (1) System head with raised hitch ball platform
• (2) Sway control cams
• (2) Trunnion spring bars
• (2) Lift brackets
• Lift chains
• All necessary hardware

⚠️ Required — Sold Separately

To complete your installation, you'll need the following components (NOT included with the 66074):

• Adjustable shank — connects the head to your tow vehicle's receiver
• Hitch ball with 1-1/4" diameter threaded shank

The shank and ball are not included so you can match them to your specific tow vehicle's receiver height and trailer coupler size.

Pro Tip — Balance Your Trailer Cargo First

Before investing in a weight distribution hitch, make sure your cargo is evenly loaded in your trailer to keep the weight balanced. Many "I need a WDH" problems actually solve themselves when cargo gets distributed properly. If you still have a hard time even after balancing your tongue weight, a weight distribution hitch should help — and the 66074 is one of the best options on the market.

⚠️ Professional Installation Recommended

Weight distribution hitch installation involves precise measurement, head adjustment, spring bar tensioning, and integration with your tow vehicle's existing hitch. While experienced DIYers can install a WDH, professional installation by a qualified towing/trailer technician ensures the system is set up correctly for your specific tow vehicle and trailer — important since improper WDH setup can be just as dangerous as having no WDH at all.
