Z1 has the gears and the seal/bearing kits to go along with them... Good guys over there!! The gears are around $550.00 and the seal/bearing kit is around $200-250. Depending on the shop, the install could be anywhere from $200-400 or sometimes higher. Plan on at least $1000 invested, if not $1300-1500. Well worth the money if you have no aspirations of throwing any boost at your Z
