GMC Denali Sierra Denali electrical assistance 2021-2026 one-year warranty - Formula Plus (front and rear)

Hayroud Formula shocks for GMC Yukon Denali - the peak of control and performance. Formula Plus shocks are specially designed for GMC Yukon Denali owners who do not accept compromises. If you notice abnormal vibrations in the Sierra's bed or "stiffness" when passing over bumps, it is time to replace the worn magnetic suspension system with the approved Hayroud Formula alternative. Technical specifications for Yukon Denali (2021-2026): Full compatibility with ADS system: the shocks are equipped with a smart electronic valve that immediately communicates with the Sierra computer (Plug & Play), maintaining driving modes and preventing error messages on the dashboard. Control over bed sway: in 6.2L and 5.3L engines, torque is high; Formula provides superior stability, preventing the Sierra's rear from deviating during acceleration or towing. Custom engineering for tough tasks: the shocks are designed to withstand the weight of the Sierra off-road (Off-Road) while maintaining the smooth luxury known in the Denali class on highways. Exceptional durability: using high-viscosity hydraulic oil and double O-rings ensures a long lifespan even in the harshest temperatures. 💡 Tips and questions for Sierra Denali owners: Q: Are the shocks installable on the regular Sierra? A: This version is dedicated to the Denali or models equipped with an electric suspension system (with fuses). If your vehicle has standard mechanical shocks without electricity, we provide the specific mechanical version. Q: Do I need to do a "tracing" or programming after installation? A: Absolutely not, once the original fuses are connected, the system will recognize the new shocks and any limited speed alerts will disappear immediately. Q: Are they capable of load and tow? A: Yes, Formula shocks are reinforced to withstand load pressure in the bed without losing their shock absorption ability.
