Your gonna have a tough time finding a factory replacement set of limbs. Probabaly have to go aftermarket, but fear not. Give Barnsdale Archery a call. They make, arguably the best limbs in the industry. Elite uses them exclusively. A set won't be cheap but will be cheaper than a top shelf new bow, and you'll have and old friend to carry in the woods.
