Ordered 2/22/26, installed2/23/26, had a gritty sound immediately, and should've asked for a replacement then but was just happy to be mobile again, 3/29/26 left me sitting on the side of the road popping starter fuses over and over... not a decent part especially since im now realizing there is zero warranty... do yourself a favor, read the reviews before you buy and dont put money in this sellers pocket
