Darton 3UR MID Liner Sleeves

With these sleeves, you can bore your 5.7 liter 3UR engine anywhere from 94mm to 100mm! Combine this with a BC stroker kit, and you can get up to 6.8 liters out of your block!!

Keep in mind that these typically have a 6 week wait time, you will need custom made pistons to fit, and also custom head gaskets. We can help you get these as well and have built more than a few 3UR engines now! 

Let us know your build priorities/goals, and we can help you achieve them!
