Eaz-Lift ReCurve R3 Weight Distributing Hitch System

Product Overview

The Eaz-Lift ReCurve R3 is a weight distributing hitch system with adjustable sway control designed to improve the safety and handling characteristics of your trailer and tow vehicle combination. It provides constant sway resistance through a full range of angular rotation, independently of trailer tongue weight.

Ratings when used as a weight distributing hitch with spring bars:

Important Notes:

• Do NOT exceed the towing vehicle manufacturer's load rating.
• Read all instructions and check package contents before beginning installation.
• CAUTION: The tongue weight rating of the spring bars represents the capacity of a pair of bars, not an individual bar. Always use a pair of spring bars of the same weight rating.
• WARNING: Disable tow vehicle's electronic sway control when a hitch with built-in sway control is in use.
• Dealer/Installer: Be sure customer receives installation instructions after hitch has been installed.

Parts List

The ReCurve R3 system includes various components. Refer to the diagram for part identification.

Ball Mount Installation

Determining Ball Height:

1. The height of the ball must be determined before assembly. Measure the trailer from ground level to the top of the ball coupler, ensuring the trailer is parallel to the ground.
2. Add approximately 1/8" for each 100 lb of tongue weight to compensate for vehicle squat.
3. Example: If coupler height is 17" and tongue weight is 600 lb (6 x 1/8" = 3/4"), the hitch setting height (to top of ball) should be 17-3/4".
4. Write down the ascertained height.

Adjusting Shank and Securing Ball Mount:

1. Slide shank into sleeve receiver; insert hitch pin (48021) and spring clip (48766).
2. Slide ball mount up or down the shank until the nearest dimension is obtained and holes align. Insert bolt (9c), lock washer (9f), and nut (9d) in the bottom hole, but do not tighten yet. This will temporarily secure the hitch head.
3. The thumbscrew (48037) is used to achieve the correct downward angle for the spring bars. Start with the top plate of the ball mount level with the ground to determine the initial spring bar angle.
4. Adjusting the spring bars down increases preload, distributing more tongue weight to the front axle. Angling them upward reduces preload, distributing less weight to the front axle. The goal is to have both the tow vehicle and trailer level with the ground.
5. CAUTION: Avoid excessive spring bar preload, which can unbalance tow vehicle axles. Insufficient preload can result in too much weight on the rear axle.
6. To make hook-up easier, raise the front of the trailer and the back of the tow vehicle slightly using the trailer tongue jack. This reduces tension between the spring bar and hook-up hanger.
7. Once the desired spring bar angle is set, insert the top bolt (9c) with serrated washer (9a). Install a second serrated washer and nut (9d) to secure the unit.
8. Before tightening bolts, ensure the set screw is locked. Tighten the top bolt to 260 ft lb torque and the lower bolt to 260 ft lb torque.
9. After the first day of towing, check the set screw for tightness.

Diagrams:

• Figure 1 illustrates maximum tilt down and up with the thumbscrew.
• Figure 2 shows the ball mount adjustment range (7-3/4" total adjustment, 1-1/4" per adjustment).
• Figure 3 shows the bolt-together ball mount.

CAUTION: Do not adjust air shocks or air bags to support trailer tongue weight. Use them only for added weight in the rear of the tow vehicle.

Hook-Up Brackets Installation

Spring Bar Insertion:

• Spring bars can be inserted into either side of the Ball Mount. The Spring Bar Locking Device automatically locks the bar in place. To remove, swing the bar to disengage the device and lift the bar out.

Positioning Spring Bars:

1. With the tow vehicle coupled and sway control off, position the spring bars alongside the trailer frame. Rotate the trunnion so it aligns squarely with the trailer, with the spring bar studs equidistant from the center of the ball.
2. Use the spring bar studs as a reference for the approximate mounting location of the hook-up brackets along the trailer frame.
3. The hook-up brackets have a 2" offset from the frame clamping location to the center of the channel accepting the spring bar. The offsets on the two brackets are opposite to allow installation on either side of the frame. Brackets can be inverted for bottom mount couplers.
4. Determine the required offset and install the brackets on the appropriate side of the trailer frame.

Installing Hook-Up Brackets:

1. Insert the hook-up bracket insert into the bracket with the raised boss facing upward.
2. Insert 1/2" flat head screws through the bracket holes, corresponding to the trailer frame height and required orientation.
3. Place the hook-up bracket spacer onto the screws, against the back of the bracket.
4. Position the hook-up strap on the opposite side of the trailer frame, aligning its holes with the screws.
5. Install the 1/2" serrated flange nuts. Snug the nuts so the bracket is held but can still slide.
6. The bracket height is set to ensure level spring bars. Adjust the ball mount's tilt using the thumbscrew for additional spring bar preload.

Loading Spring Bars:

1. Use the Hook-Up Tool: Insert the pivot pin into the hook-up hanger's pivot hole. Position the spring bar in the tool's throat and rotate the handle upward until the bar seats on the hanger. The spring bar stud should align with the slot in the hanger.
2. If the stud doesn't fall freely into the slot, check hanger placement and ensure sway control is disabled.
3. Secure the spring bar by inserting pin (48743) through the hanger's pivot hole.
4. The hanger should rotate to accommodate the angled bottom of the spring bar. Ensure the bar's bottom contacts the hanger across its entire width.
5. Confirm the spring bar stud is centered in the hanger slot and the ball mount is centered.
6. Re-measure the distance from the coupler center to the hook-up hanger center on both sides; they should be equal. Reposition hangers if necessary.
7. Tighten the nuts in an alternating pattern to securely clamp the hook-up hanger and strap to the trailer frame.

Releasing Spring Bars:

1. Raise the trailer front and tow vehicle rear approximately 3" using the trailer tongue jack to release tension.
2. Remove the pin (48743).
3. Insert the Hook-Up Tool pivot pin into the hanger's pivot hole with the spring bar in the tool's throat.
4. Rotate the tool downward to relieve spring bar preload. Remove the tool.

How-to-Use

Activating the Sway Control System:

• Simply tighten the activation bolt until the desired sway resistance is achieved. Use wrench (48758) for activation bolt (11, 7c).

Disengaging the Sway Control System:

• To disengage, loosen the activation bolt until the clamp force is removed. This is recommended for hook-up and travel in adverse road conditions.

Storage:

• Store the hitch in an area protected from environmental elements.
• Remove preload from the sway control system before storage by repeating the disengagement steps.

ReCurve Maintenance:

• Lubricate the trunnion spindle using the factory-installed grease fitting.
• Ensure this area is sufficiently lubricated with a suitable wheel bearing grease before each use.
