You have gotten straight answers. You need a lifter that has pressurized oil to the bearings on a street app, plain and simple. There are lifters that do that and there are also quite a few that dont. How many people on here or people that you know personally that run solid rollers IN A MOPAR on the street? MRL's are just the best solid roller I have found for the money PERIOD. Not a commercial, just a straight answer.
