I spoke with Mathews, Hoyt,and PSE, they all stated that once you PURCHASE REPLACEMENT LIMBS, RISER, or CAMS, that part is WARRANTED to the one that PURCHASED it, regardless if the original bow purchase was from a private citizen. Oh, when you buy and install replacement parts on your vehicle, they are warranted, as long as you purchase from and have them installed by an authorized dealer. Man better call a dentist, there are alot of exposed nerves out there. it will all be alright, have a great season. just Rod
