Jeep 4.0 inline Six Cylinders are EXTREMELY common to Crack, Bust, Slap, And even have wrist pin noises. Dex highly recommends getting ahead of the issue with New Updated pistons and keep your engine one the road and avoid having to purchase a used engine with the same problematic pistons or causing so much damage to your engine that it becomes unfit to rebuild.
These are New Seal Power pistons for STOCK BORE SIZE!! Already pressed onto rods, ready to drop in and solve some noise issues. Rings will need to be installed. At the moment we are just doing stock bore size but if this works we may look into alternate bore sizes.
You'll see prices below, and at if you cancel out the Connecting Rod core charge, you should have around $435 in a set of pistons that should keep your engine going for a long time. I do want to work on a service where you can send yours in and we just change them on your rods and avoid core charges. But if you do send your old Piston/Rod assembly back I will issue the Full charge back to you.
CORES Be sure to keep rod caps in factory location per rod, If caps gets mixed up I can't risk re using them as a rod so no core refund, and I do provide return label with purchase.
New Seal Power Pistons - $189
New Rings Mahle or Hastings $71
Press on/off/clean Labor $175
Connecting Rod Core Charge $120 ($20 each rod)
If Return Shipping cost more than average, I may subtract from return core prices. If that is a concern, may be best to email before hand.
Total Cost $555 or $435 after core exchange (rod casting # will vary, but will work)
Questions- Email Me at dexjeeps@gmail.com
If you would like to just send me your rods/bad pistons and avoid the core charge I would gladly entertain doing it that was as well, just email me.
