Hi I have a 03 5.9l and was wondering what the pros and cons are for changing to viper rocker arms. Is that all you have to do or should I put springs on to. I don't race the truck just pull my pontoon and jet ski and was looking for more towing power and fuel economy . The truck I all stock motor wise just [email protected] fipk ngk plugs and amsoil in motor.

Thanks Dave

IMO, dont go to the viper rr's. they're not a full rr. Go to www.harlandsharp.com and get you 1.7 non adjustable rr's rockers. You wont need anything else for the swap. They'll even fit under the stock valve covers. I have them on my 99 5.2 and it was the best mod for my money. Give'em a look and do a search on them. You'll find many happy campers with them. Good luck!

Running a set on a 3.9 and agree with Scojodak. NO problems just bolt them down and GO NO other modification nessary ; use stock pushrods, no guide plates required ,no baffle beating ,no brainer
