3. Assemble the side brackets to the crosstube assembly as shown above. The bracket flanges point outboard for 37-1/2" and 38" wide frames.

The bracket flanges point inboard for 34" wide frames. Slots in the crosstube must line up with the holes in the side brackets. (Caution: Do Not

drill new holes in any receiver part.)

4. Install the 1/2-20 x 1-1/2 hex bolts, hardened flat washers, and flange locknuts as shown above. Do not substitute regular nuts for the locknuts. Tighten all 1/2-20 fasteners with torque wrench to 90 Lb.-Ft. (122 N*M)

5. Read the General Notes and then continue installation by following the instructions for your particular vehicle application which is listed on the following pages.

Note: check hitch frequently, making sure all fasteners and ball are properly tightened. If hitch is removed, plug all holes in trunk pan or other body panels to prevent entry of water and exhaust fumes. A hitch or ball which has been damaged should be removed and replaced. Observe safety precautions when working beneath a vehicle and wear eye protection. Do not cut access or attachment holes with a torch.

Spare tire carrier will have to be modified to retain under vehicle stowage.

Spare tire can also be relocated elsewhere on the vehicle.

Installation depends on vehicle configuration: Configuration 1: Configuration 2: Configuration 1 - All holes require drilling

1. Position and center the receiver assembly on vehicle frame. Locate rearmost slot in receiver 1" forward from the edge of the large existing hole at the end of the frame. This is

required so that the forward attaching flange does not ride on the crossmember rivet. Clamp receiver to the frame.

2. Center receiver crosstube assembly on vehicle and tighten the 1/2-20 hex bolts installed as shown on page 1 to 90 lb.-Ft.(122 N*M)

3. Using slots in brackets as templates, center punch and drill six

(6) 1/2" diameter holes in frame. Install fasteners as shown for configuration 1.

Configuration 2 - uses existing holes

1. Position and center receiver over large existing hole at the end of the frame. Center and forward slots will match with existing holes. Secure with fasteners as shown for configuration 2.

2. Center receiver crosstube assembly on vehicle and tighten the 1/2-20 hex bolts installed as shown on page 1 to 90 lb.-Ft. (122 N*M)

General Notes

1. Attachment holes must be drilled for most applications. In some cases existing holes in frame may line up with some of the holes in the receiver side brackets. When holes do not match precisely, file or grind material from the vehicle frame to match the hole in the receiver side bracket.

Warning

2. When positioning receiver on vehicle frame, make sure that the crosstube assembly does not contact any gas tank supports or spare tire hanger brackets if vehicle is so equipped.

3. Be careful to avoid drilling into the fuel tank, wires and fuel or brake lines that are sometimes located inside the vehicle frame sections.

4. Deburr all edges of any holes drilled through frame and/or crossmembers. Proper deburring will ensure that fasteners and side brackets will sit flat.

5. Always wear safety glasses when drilling.

6. License plate mounting bracket will have to be relocated on vehicles without a factory installed bumper.

This product complies with safety specifications and requirements for connecting devices and towing systems of the state of New York, V.E.S.C. Regulation V-5 and SAE J684.

: do not correct hole mismatch by drilling, because drill can suddenly bind causing drill motor to "kick back" or drill

bit to break, possibly resulting in personal injury.
