Slapper Bars

Ive had slappers on my duster since I got it. they too angle down a bit but the only time they've ever contacted the ground is when I go over a small dirt ramp I have just near my car port. never under braking or other obstacles. then again, my car is standard height, so if you lower the car at all, you might find an instance or two where they contact.

I think those should be fine (IMO)
