A shocking difference.
Purchased the Bilstein 5100's to replace the inefficient ranchos that came on my 2015 GMC sierra 1500. Install was a breeze, remove upper bolt and lower bolt, remove old shock and in stall the new. The ride is firmer in good way, and it feels more planted. Going over rough roads or bumps you feel them, but it settles much faster than before. Overall huge improvement.
