Clip in tabs are a must have for vehicles that have the shoulder portion of their harnesses bolted in, rather than wrapped around a harness bar.  If you need to take the seat out for any reason (to clean, or access the battery) clip-ins make it quick and easy to disconnect the harness. Versus if you have a standard tab, where you will need to use tools to remove the harness.  These Clip-in Kits are only designed for the shoulder belts of the harness, since the lap belt tabs are sewn in, and not easily switched out.  If you would like a lap belt section with clip-in tabs - see our Latch and Link Lap Belt or 5.3 Custom Harness. Kit includes: One Clip-in tab One eye bolt One large washer One lock washer One nut (Two kits required per harness)
