🔧 BDS 2.5” Coil-Over Suspension Lift Kit with FOX Performance Elite Shocks

For 2019–2024 Chevy Trail Boss & GMC AT4 1500

Give your Trail Boss or AT4 1500 a true performance makeover with this 2.5-inch lift kit featuring FOX Performance Elite 2.5 coil-overs from BDS Suspension. While it’s called a 2.5” kit, actual ride height is closer to 4.5” with the coil-overs installed—giving you the extra clearance and aggressive stance your truck was built for.
