Keep Accidents in the Diaper, not on the Track!


About the DRE Engine Diaper

  • What does an engine diaper do?
    -When installed properly, an engine diaper (or lower engine containment device) will keep oil and debris from getting onto the track.
  • How hard is it to install?
    -It’s very easy to install! Because we incorporated quick release buckles and 4 simple straps, they install simply and snugly around your engine.
  • Why do I need an engine diaper?
    -First and foremost, safety. A DRE engine diaper is much cheaper than replacing a car. Having a DRE engine diaper also means less track downtime and there are IHRA and NHRA requirements.
  • What diaper are Sportsman required to run?
    -You are only required to run an NHRA accepted diaper, as per chart on NHRA Website.
  • What is SFI 7.2?
    -NHRA has changed the rules. YOU DO NOT NEED TO RUN a SFI 7.2 diaper to any sportsman car.
  • Why are DRE engine diapers better than others?
    -Ours are hand-crafted for YOUR engine. You gather measurements and information about your engine and we custom build your DRE Engine Diaper using only the finest materials available, such as Kevlar®. The fabric we use does not absorb oil, compared to ballistic nylon which soaks up oil.
  • Why Kevlar®?
    -Kevlar® is a high performance, light weight, thin, durable, flame resistant material. If it’s good enough for bullet-proof vests, then it’s good enough for your engine diaper!
  • Is there a guarantee/warranty?
    -Your satisfaction is guaranteed or your money back.
  • How long do they last?
    -Our Sportsman and Sportsman Kevlar diapers are made of very durable, water proof material which is easy to clean and has removable pads. They should last for years. No recertification needed. The SFI 7.2 DRE Engine Diaper is certified for 5 years, at which time it must be recertified by DRE under SFI Specifications.
  • Where are they made?
    -DRE Engine Diapers are made in Cerro Gordo, IL, USA.
