CURT 70146 is a custom tow bar base plate for 2019-2021 Chevrolet Silverado 1500, 2021-2024 Chevrolet Suburban/Tahoe & GMC Yukon/Yukon XL, 2022 Chevrolet Silverado 1500 LTD. Fitment details: Z71 Only (Suburban, Tahoe); AT4 Only (Yukon XL, 2021-2024 Yukon).
It is for dinghy towing the vehicle with a tow bar. The base plate bolts to the vehicle frame and gives the tow bar a solid attachment point, and it spreads towing forces equally to reduce stress on the frame. The twist-lock tabs install and remove as needed, and the base plate is concealed for a factory look. It is physically tested to gross vehicle weight rating (GVWR). Safety cables and installation hardware are included; the tow bar is sold separately.
