On my '21 Tremor with 50k miles, I replaced the factory original Tremor shocks with the Fox 2.5 Performance Series. Gotta say, it's and night and day difference. So much smoother ride. I have an aluminum flatbed and keep a small camper on the flatbed at all times. It made me regret not doing it sooner. Just thought I'd throw that out there for people that are looking into shock options.
