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 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!
