When I shopped sliders it seemed every quality slider was in the 800-1k range, but I wanted them powder coated, a removable top plate and a rear kick out .. the top plate really helps keep the side of the vehicle clean , helps as a step and the kick out has helped me more than once by pushing the vehicle off of rocks and trees .
FWIW I went with white knuckle DOM tubing, 15 degree angle for clearance, and removable full top plate . Seems the shipped price was around $900 it I couldn’t be happier. Remember, one good shot to the rocker or the side of your vehicle will be a heck of a lot more than the slider cost. Learned from previous experience, It was the first mod I did to my 100
