First off, congratulations on the purchase of your LS Fab Universal Scissor Hinges and thank you for your order and support! We put this list together to help you have the best chance of success with your hinges and learn from our experience.
- There is a left and right hinge. The direction of the bolt heads and assembly of the hinges is different from passenger side to driver side. We recommend bolt heads facing outward of the box — this also makes the LS appear in the proper direction.
- Tighten or loosen each bolt to the desired function of the hinge. If your gas struts are overpowered, you can tighten the bolts a bit to slow the opening of the tilt bed down. Don’t over-tighten though, as it can prematurely wear the bushing out and they won’t operate smoothly.
- When mounting, don’t leave more than 4-5″ of overhang ahead of the hinge. These are designed to mount as close to the front as possible to keep everything tight — more overhang than that and the floor can contact or drag when opening.
- Hinges need to be mounted at 90 degrees when the bed is fully closed. They can close past 90, but that’s not how they’re intended to be used — at the bottom they should be nice and straight, at 90 degrees.
- If disassembling the hinges for paint or powder coat, take lots of good assembled photos of each hinge — they’re different from passenger side to driver side.
- If powder coating, do so with some spare 3/8″ hardware in the holes, as tolerances are super tight and if powder coat gets into the hardware holes, they may not fit the 3/8″ bolts.
- Leave a ~1/2″ gap at the back of the tilt bed frame to allow it to hinge out and away as the bed opens — the hinges articulate in a curved motion, slightly moving the floor away as it opens.
- If you have any issues at all, reach out to us! If you happen to melt the bushing or run into any trouble, we’re here to help or get you replacement pieces. Good luck with your install and thanks again for your order and support!
