Question:
I have a 2021 GMC Sierra 1500 AT4. Will this fit or do I need spacers because of the factory lift?

Expert Reply:
The Timbren Suspension Enhancement System item # T53MR includes a 1" spacer that is optional for install. The suspension enhancement system should have a 1/2" to 1-1/2" gap between the rubber spring and contact point of your 2021 GMC Sierra 1500 AT4 when empty. A partial load, or other accessories will reduce or eliminate the gap. The overall height of this system is 5 3/4" so you if have larger than a 1-1/2" gap you will need to add the Timbren 1" Spacer item # TA25723-90AD00 or the 1/2" spacer item # TA25722-90P00.
This is the severe service kit that is typically used with a slide-in camper or salt spreader. If you need something less heavy duty you will want the SumoSprings Solo Custom Helper Springs item # SS45FR.
