This is it folks... You bring us your 392 HEMI Wrangler and we give you back a 426 HEMI stroker powered monster. This price includes everything from A to Z.

Its time for another legend to make its way into the Wrangler platform. The legendary 426 HEMI. Not just any 426, OUR Gen3 426 HEMI stroker engine. Since 2006 we have been in the business of developing, building and improving the newest HEMI platform. No other shop, Jeep, HEMI performance shop or otherwise has the experience and portfolio that we do (see our primary site here www.modernmusclextreme.com).

This performance upgrade will net you nearly another 100hp over top of the stock 392 HEMI. Not to mention the added torque and wicked sound of the custom performance camshaft. This will definitely set you apart from the crowd and pull those 40s and your boat or camper like it isn't even there.

This Conversion Includes:
  • Our 426 HEMI Engine
  • Long Tube Headers and High Flow Cats by ARH
  • Custom Chassis Dyno Tune by MMX
