Hot Rods was recommended by my mechanic over Wiseco, due to quality of product. Full bottom end rebuild was quick and easy with this kit, that includes everything needed, including new oil seals. You will need to buy oil. Ran the Blaster all last weekend without mechanical issues. Appears just as strong or stronger than before the rebuild, and did not touch the top end. Great product and worth the additional $15 - $20 more than Wiseco.
