If you are ready to take your Frontier to the next level, this is the only system that can take it there. We are happy to release the first kit of its kind for Nissan vehicles, the CALMINI Solid Axle Swap. This kit is over 85% bolt-on with the only welding to occur on the donor axle. Our complete system allows for the entire removal of the stock IFS system and a full replacement, with a full center skid, with a solid axle out of an early model Jeep Wagoneer. The donor axle this kit is designed for is out of a 1980-85 Jeep Wagoneer model Dana 44 (D44), with a driver's side drop and a non-vacuum actuated disconnect.
