Question For Rear Bump Stops

Currently I am re-doing my suspension (going with Dobinsons again with their MRR kit) and im changing out my bumpstops. I've already got the replacement for my front ones from durobumps, however I'm stumped on what to do for the rear. With a 3 inch lift do I need their extended height ones for the rear? And how necessary is their flip kit for the rear?

 

Every truck is different, even two trucks of the same model year with the same components may require a slightly different height bump to get the most travel out of the setup while not damaging shocks or leaf springs. Ideally you would cycle your suspension to max compression and extension to determine the appropriate limits, and adjust bumps accordingly. U-bolt flip kits don't change much, as the springs still ride on the same point on the axle, but best to have them installed before cycling, if you decide to go that route.

 

AccuTune came out with new ones that are adjustable.
