I installed sliders from PP Engineering and thought others might benefit from my experience.
The sliders are top-notch, rock (pun intended) solid and fit perfectly. The rear notched holes help address individual frame idiosyncrasies. The sleeved inserts really snug-up the front and middle attachments. No drilling required.
I primed them with Magnet Paints Chassis Saver (UPC99) and then finished them with their Monstaliner bedliner in black which matches the night armor very well. BTW-Monstaliner will send color chips if you're thinking of using a different color.
The sliders seem to improve the on road handing although it's very subtle. Feels like the X hugs the road a little tighter and doesn't hunt around as much traversing pot holes and rough patches. Center of gravity???
Attached are pics to document the steps.
