Why use reUp Short & Long Blocks and Engines

  • Quality and reliability: reUp short/long block and engine components are remanufactured in production environments with supporting quality systems.  Assembly is completed by trained personnel with the same equipment, processes, and tools used to build new units.

  • Component fallout: Core credit is determined based on visual inspection of core. No added fees are applied if components fall out later in the core process.

  • Core eligibility period:  Engine and short/long block cores are eligible for return for 6 months

  • Warranty:  Waukesha Extended Limited Warranty applies: one year from date of service or two years from sale.

  • Shipping:  Short blocks are shipped with custom skids and bags which prevent damage and corrosion during transport.
