PARTS INCLUDED
  • • (1) Oil Cooler Hose
  • • (2) Worm Gear Clamps
  • • Mishimoto Lifetime Warranty
Key Benefits
  • One-piece silicone outlasts the factory hose where it actually fails - the OEM rubber hose cracks and fails at the bend under repeated heat cycling; the Mishimoto replacement is a single continuous silicone piece that holds its shape through the bend, with no weak point to split or leak on the trail.
  • Smooth internal taper prevents pressure pockets - the bore transitions without a step or ridge, so coolant flows without restriction or turbulence at the junction where the plastic joiner previously interrupted flow.
  • Reinforced fiber construction outlasts OEM rubber - embedded fiber reinforcement resists expansion, collapse, and abrasion under sustained system pressure, where factory rubber softens and degrades over time.
  • Drops in without modification β€” confirmed direct fit for the 2021+ Jeep Wrangler JL Rubicon 392, no cutting, fabricating, or adapter work required.
  • Own it for life - backed by Mishimoto’s Lifetime Warranty, your investment is protected long after install day.

The factory oil cooler hose on the 2021+ Jeep Wrangler JL Rubicon 392 cracks and collapses at the bend - the OEM rubber cracks and fails under the repeated heat cycling the 392 V8 generates in trail and low-speed use, splitting at the point of greatest flex. The Mishimoto Silicone Oil Cooler Hose replaces the factory hose with a single continuous silicone piece engineered to hold its shape through the bend, eliminating the failure mode at its source.

The bore follows a smooth internal taper through the full length of the hose, eliminating the pressure pockets and flow restriction the plastic joiner creates at the step change. Embedded fiber reinforcement throughout the silicone wall resists expansion and collapse under sustained pressure - where factory rubber softens and distorts over time, the silicone construction holds its shape and seal. Worm-gear clamps are included for a secure, field-serviceable connection at each end.

Direct fit for the 2021+ Jeep Wrangler JL Rubicon 392. No drilling, cutting, or modification required. Backed by the Mishimoto Lifetime Warranty.
