This is eye opening and quite upset I'm so late to reading all this. Amazon got them in stock for 53 bucks. Well worth a shot. I have a 2014 Sierra 5.3 with adjustable petal, I've read plenty about the wood trick and all. I've always said this truck is god awful slow for acceleration time. I go in my girlfriend's newer v6 Grand Cherokee and it's like a ROCKETSHIP compared to my truck. This is WELL worth a shot. I checked and I have the older part number. Not alot of flex to it but I think I'm going to give this a go as well. Sent from my SM-N950U using Tapatalk
