Question:

2018 Chevy Colorado here. Best choice spring system for constant truck bed weight of 600lbs? Tembren bump stops, Tembren springs or Sumo springs? Thanks for your help. Ron

Hey Ron! At 600 lbs I would get the SumoSprings Solo Custom Helper Springs # SSR-212-40. These have 1,000 lbs of load support so they can handle whatever you're carrying plus a little extra if needed. They're also more forgiving when compared to the Timbren so you won't end up with a rough ride.

What are you carrying in the Colorado?

Thanks for the information and prompt response! I’m carrying a GFC pop up camper (400 lbs) plus build stuff.

@RonnieA you're welcome! With a GFC camper and the additional gear staying in the bed, I think the SumoSprings will be a great match for your setup. They'll give you the support you need without making the Colorado unnecessarily stiff.
