  1. Everything I get here is the best!!! 5 Star Review

    Posted by on May 2nd 2018

    I’ve done injectors hpop rebuild fuel mods oil mods and a lot of other things I can’t even remember. I got ahold of a real diesel mechanic who did the research and sent me to Riffraff. I ordered bocoos of stuff from them. I talked to Clay at least 3 times and it was like visiting with an old friend. We changed to different tuner with dial on the dash and I’ve got the best ride with awesome power and I mean real power!!! 2001Excursion 7.3. I’ve been pulling disaster relief trailers all over the east coast since last hurricane season and headed out this weekend for another trip. You bet I’m keeping Riffraff’s number.

    Was looking around for a piece of pipe, nobody had anything in town. Ordered this, came in a couple days later and had it on in about two hours. Perfect fit! As always the Riff Raff crew knows what we’re looking for.

    Product was an exact perfict fit to delete my muffler, and Riffraff's excellent customer service got it here two days earlier than it was even supposed to. This is absolutely the best place to order any parts from, hands down. Thanks, Riffraff!
