Maximize EcoBoost Engine Performance

Cutting-Edge Guide Bushings & Tooling Bits
  • Superior Quality: Our drill bit tooling surpasses Aerospace standards, offering precision and durability.
  • Efficient Repairs: Drill and tap bolts that break inside the crankshaft without removing the crankshaft bolt or harmonic balancer.
  • Avoid Costly Repairs: Prevent the risks associated with traditional methods that can lead to an engine teardown.
Common Issues with Crankshaft Bolts
  • Risk of Breakage: Crankshaft bolts can break when torqued past OEM specifications.
  • >When It Occurs: This often happens during the removal, replacement, or adjustment of the harmonic balancer or pulley.

An engine pull and tear down is over 35 hours...these kits can fix it in about one hour!

To date, the only solutions have been to either pull the motor and have the crankshaft machined, or to freehand drill the broken bolt and attempt extraction with an easy-out, which always risks breaking as well. The goal with the 3.5L EcoBoost Crankshaft Repair Kit, as with all ProMAXX Tool kits, is giving technicians much more productive repairs and an immediate return on their tool investment.
