12 Pcs Rocker Arms and Lifters with Gaskets Kit Compatible with 3.6L Engine Challenger Avenger Grand Caravan Promaster 1500 2500 3500

To do both heads you need 24 of each. I did not catch this when ordering. I realized it the day off dismantle. I had to buy extra ones at higher prices locally

I purchased these to fix the infamous 3.6 tick in my bank 2 side of the engine: parts fit into place. Once the engine was started, it began idling rough and throwing the P0300 random misfire code. I checked compression on both sides. Bank 1 was good. Bank 2 had zero compression. After a week of investigation, it turned out that the lifters we’re about a millimeter too short and the rockers were pitched at an angle that didn’t allow the Caleb to close at all. I replaced the new parts with Mellen brand parts and the engine fired up nicely. Perhaps these parts that I bought here are meant for something else. Definitely not a 2012 jeep wrangler sport with the 3.6

Lifters are too short and rocker arms dimple are to shallow and don't allow lifters it sit properly

I did change one side after my OEM lifters barely started making noise, changed the 12 rocker arms and lifters and after all the work and money to do this change the noise was 10 times worst, my jeep sounds like a diesel now, I know I have to wait for the lifters get fully lubrication but even after 2 weeks of use the noise persists. Make you a favor and buy OEM or any other good known brand. My return window is closed now, that means I am screwed.

Don’t waste your money on these, spend the little extra and buy oem ones from dodge, I installed these and they make all sorts of noise! Sometimes you gotta bleed the air out of the hydronic lifter, but even after a week of driving they are still way noisey.

Couldn’t use
