Underbed Installation Kit and 5th Wheel Hitch for a 1989 Ford F-250 w/ 8' Bed

Question

Question:

Scott S replied to a question I submitted regrading a 5th wheel hitch system for my 1989 Ford F250 Super Cab 3/4 T 4x4 8 ft bed. Attached is a picture of my F250 leaf springs. I dont know if the picture depicts overload/lift springs. I need to determine which custom underbed kit I need, the 1110-5W or the 1100-5W based on the springs I have. Thanks

The only 5th wheel hitch that we have that is compatible with your 1989 Ford F250 Super Cab 3/4 T 4x4 8 ft. bed with lift springs and uses below bed rails is the B&W Companion 5th Wheel Trailer Hitch # BWRVK3500-5W.

If you mean Overload springs when you say lift springs then the correct below bed installation kit is the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1110-5W.

If you do not have Overload springs then the correct install kit is the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1100-5W.

This is not your traditional rail mount system, the B&W Companion 5th Wheel Trailer Hitch # BWRVK3500-5W attaches to the install kit using the turnover ball hole and the system can be used as a gooseneck hitch when the 5th wheel hitch is removed and turnover ball put in place.

Thank you for the picture. From the picture we can tell that you do not have the overload springs. That means the correct underbed kit for you is the Custom Underbed Installation Kit for B&W Companion 5th Wheel Trailer Hitches # BWGNRK1100-5W.

Answer 1

I actually recommend going with the Demco Premier Series Above-Bed Base Rails and Custom Installation Kit for 5th Wheel Hitches #DM8552005-71 instead of B&W. Mainly because B&W doesn't offer just the frame brackets separately, so…

If you look at your rear leaf springs, and see an extra leaf as shown in the diagram, you have the overload spring option. For a 1997 F350 with overload springs, you'd need the B and W Turnover Ball #BWGNRK1110. If your truck does NOT have the…

You will have to go with a sliding hitch to allow the trailer to make tight turns. For a trailer 8 feet wide the only bed length that's going to allow 90 degree turns without a slider is a stationary hitch. That being said you have two options.…

Hey Bryan, that's a good question. The pricing can definitely be misleading, but I wouldn't use it to judge the quality of the tire. A lot of that comes down to promotions, inventory, and whether you're looking at a tire by itself or…
