Question about Dura-Lift spring conversion kit setup

[meazz1]

I’m installing a Dura-Lift spring conversion kit, and I noticed the center bracket already has a built-in bearing. However, the kit also came with a separate bearing.
I’m planning to use a single spring since my garage door weighs under 90 lbs.
Do I still need to use the separate bearing, or is the built-in bearing in the center bracket sufficient for this setup?

bearings on the ends are what is critical. That's where the load is. Look at your end plates and see if one of them needs a bearing.
