These people are thieves. You spend $1600 on a part, 800 of that is the core charge. You take your old part in and get refunded the core charge. After your part is installed you get bAck on the road and there is either something wrong with the part or it isn't the right part, since they don't always have the exact name brand part so the part number isn't the same. You are at their mercy there.. and more than once we have gotten the wrong part. So after going through 3 belts in 4 days, we take the part out and take it back... They won't return the part, they won't replace the part and they won't give you your money back, they give you back your part and you lose $800 that you paid for the part that didn't work because it had been installed. How you're going to know it doesn't work or is wrong before you install it I'm not quite sure.. unless you're psychic. So they get to keep that part if you want your core back that was originally in your truck. Which still worked but had been making a noise and trying to be proactive to prevent a breakdown, we had replaced.. what a scam. So now they have their part back which they can sell to somebody else and we are out $800. If I could do negative Stars I would. read more
