Question:
Hello, I have a 2021 GMC 1/2 ton AT4. Have the front leveled - Rear is stock. Looking for helper springs to reduce sag. What do you recommend? Timbren T28MR or SumoSprings SS45FR?
asked by: Jon K
Expert Reply:
The Timbren Suspension Enhancement System part # T28MR and SumoSprings Solo Custom Helper Springs part # SS45FR are both great options for a 2021 GMC Sierra 1500 AT4. I recommend the SumoSprings as they don't typically ride as rough as the Timbrens but the Timbrens also offer more support. They are both however bolt-on, no maintenance options.
Please note, a leveling kit won't warranty any additional spacers to be added to the rear suspension enhancements. These kits are also not compatible on models with Adaptive Ride Control.
