i currently have some djm 2" drop shackles on my silverado. but i have heard that djm is a shitty brand, should i take that in to consideration n replace them or ignore that n keep them??. i've had them for about 2 months now and havent had any issues. n if i were to replace them, what brand do yall recommend?? also, ive heard that ground force shackles are a bit taller n provide like a 2.5 drop. anyone else heard bout that??
