"A replacement seat slider is designed to fit your OEM factory style seat bracket of your Jeep. 4WD sells replacement ones individually for YJ model Jeeps and Rugged Ridge manufactures them. The sliders are made for the front seats only and for the passenger side you may need to drill new holes to your factory seat bracket to make things compatible. These seat sliders can be great upgrades after your existing slider is worn down from years of use. 4WD is your one stop shop for all things Jeep seat related from sliders to covers to headrests. "
