Aggregate ratings are generally favorable, with most ratings in the five-star category, but a smaller low-star share shows that experiences are not uniformly positive. The rating data does not identify customer-reported reasons, so it cannot establish fitment or installation outcomes. For a vehicle-specific replacement, confirm the truck configuration and follow the listed sealing and screw-tightening guidance.
