• Sidewinder Replacement for Dexter Fifth Wheel Pin Box
  
• To match up a sidewinder to your 2008 Palamino Fifth Wheel pin box, you will need to call the trailer manufacturer with your VIN or serial number and they can provide the coupler type and part number. I checked with Dexter and they do not make pin boxes, so the pin box you have is manufactured by another company. With age and use, the manufacturer name may have rubbed off, especially if it was a sticker. Once you find the manufacturer name and part number, you can easily match it up with the

• Cougar SAB 293 Trailer Not Level With 5th Airborne Cushioned Pin Box
  
• Can you move the head of the HighJacker up higher on the legs? I am not very familiar with the Highjacker fifth wheels, but if they are comparable to the Reese, Curt and Draw-Tite units, you should be able to unbolt the head from the legs or sliders and move the head up. If the trailer rode level before the 5th Airborne was installed, it is possible that you have the wrong model 5th Airborne. If you can give me the make and model of your pin-box, I can make sure you have the right 5th Airborn

• Hitch Trailer Before or After Filling Air Spring on a Fifth Gear 5th Airborne Pin Box Coupler
  
• First, hitch the trailer to the truck, then add air. Proper pressure level depends on many factors like truck used and what trailer the Airborne is on. Start at 80-100 PSI, if the ride is too stiff, let some pressure out. Too soft, add some more. Do not ever exceed 120 PSI. If you cannot get a good ride, then the air spring may need to be adjusted. See page 4 of the instructions. I would let most of the pressure out before you un-hitch the trailer from the truck.
