The definition of OEM replacement exhausts

OEM exhaust replacement systems should have the following characteristics:

  • Exhausts must suit a specific asset type and model
  • Replicate the OEM exhaust path without modifications
  • Compatible with OEM engines and bolt onto turbo outlets
  • V-band clamps and hardware should match existing OEM exhaust parts

What makes our OEM exhaust upgrades better?

Combining specialised product offerings and unique insights allows us to create the perfect exhaust system. Aletek exhaust systems increase on-site productivity. Our OEM exhaust upgrades are available as complete systems or parts for direct installation on Cat®, Komatsu, Hitachi, Liebherr and Terex assets.

Invest in the productivity of your fleet

Mining operations, fleet performance, and maintenance have the same goal: productivity. A haul truck, dozer, or excavator’s exhaust system is subject to significant operational demands.

  • Reduced downtime and maintenance expenses through improved reliability
  • Proven operational durability
  • Commitment to keep essential asset parts in stock for less downtime
  • A strategic upgrade that reduces TCO by 30% (estimated)
