    Anyone changed seat cushions yet?

    Got mine done. Went with the seat shop durafoam. I figure being 290lbs I need a durable seat cushion! I think the old one has had enough.

    Anyone changed seat cushions yet?

    5 years and over 70k miles of hauling my big butt around have taken a toll on my seat cushion. I’m finding foam under the seat now so I know it’s time. I don’t want to go OE again since it will probably fail again in a few years. I’ve seen Geno’s and The Seat Shop with “upgraded” cushions. Has...

    Need help deciding on flowmaster muffler

    I have a Super 40 and love it. Of course I still have cats and resonators. I imagine without cats it would sound even better!

    Quaker stateU.D oil

    I’m a QSUD user as well, went 7500 miles on my first service with it. Have about 700 miles on the second. Engine runs quietly like I think it should. 5w30 has done well. I’ve noticed a slight drop in mileage but if it protects my valvetrain it’s worth it.

    this is the muffler for hemi

    I’ve been a Flowmaster guy since 2003 when I got my first V8 car (Lincoln Mark VII) and I’ve had their mufflers on everything since then. Stainless Super 40 on my Hemi, same muffler on my OBS Chevy, and soon to have an original 40 on my 4.3 S10 I just bought.

    2015 6.4 Hemi valve train is smoked and getting a new motor

    Mine has 101k on it and has had those startups randomly during the 5 years I’ve owned it. It makes me cringe and also makes me want to throw the for sale signs on it too. Mine just rolled out of the CPO 7/100 warranty too.

    Cam and Lifter failure

    I’ve seen over 10 Hemi valvetrain failures at my work alone. One was a 2013 Ram that had 177k, another was a 2011 Ram 2500 with 90k, and the others were 2013 and 2015 Chargers that had anywhere from 40-110k miles. These are Sheriff’s Department vehicles other than the 2500 which is a public...

    Better flowing intake for 5.7 w/Ecodiesel lower airbox

    Has anyone who has done this modification noticed improvements in fuel mileage? I wonder also if my exhaust would sound a little throatier under throttle.

    Gas mileage!

    According to my cluster, I average around 17.5 with a 5.7/6 speed. I've stretched mine to 21-22 on road trips.

    Engine chatter upon startup

    My truck has done it a handful of times since I’ve owned it. Most recently after it sat for 8 days after a vacation it did. I’ve since changed the oil to QSUD 5w30 with hopes it delays the camshaft and lifter death. My truck has 94k on it.

    Suggestions for a good quality sunshade.

    I own the WeatherTech shade. 4 years of Georgia heat and many trips to Florida and it still has held up like new. In fact, it’s seen in my avatar.

    Driver Seat noise

    Did you ever get yours fixed? Mine started doing it.

    Driver seat noise?

    Mine is doing it now, I can feel it, usually when I think I am making a left turn, it's driving me nuts.

    Calling QSUD Users!

    I’m sold! After 9200 miles it has more moly than what I am swapping from has in a VOA (Havoline HM Syn Blend 5w20)
