*Ceramic Coating Details -

The Turbo Black ceramic was formulated for exhaust temps up to 2000*F and will hold in at least 60% of the heat from radiating out under your hood. Not all black coatings will achieve that function. These coatings have been specifically formulated for use on military aircraft.

By retaining the heat energy your turbo will spool up faster and more efficiently. We double coat the outside of the housing to protect it from rusting and it results in a much longer attractive finish while retaining heat. The two main functions of the coating is appearance and function longevity of your engine parts and gaining a more efficient running engine.

Please Note: We have head rumors of "knock-off" Garrett turbos being sold at very low prices.  We may be more than other companies but you can rest assured we get them directly from Garrett unlike many other resellers.

  1. Great Turbo 5 Star Review

    Posted by on Jan 31st 2016

    I bought this turbo to replace my stock one back in November and has been great ever since. Spools up fast, sounds like a jet engine, and less smoke. Only issue I had was the intake boot was a little long but I made it work. This is a great turbo!! Oh and check your up pipes, much easier to change while your switching turbos.

  2. Awesome Turbo!!! 5 Star Review

    Posted by on Jan 18th 2016

    This was a great addition to my truck. It just runs so much better, I can't wait to pull my 5th wheel. Had stock turbo w/Banks 1.0 AR housing, ATS compressor housing and Wicked Wheel. No comparison!
    Sounds like jet plane! Also EGT's down, power up, less smoke!
    I got ceramic coated turbine housing, love it!
    The turbo is all around top quality. Comes with everything for install!
    Check your up-pipes before doing turbo, much easier to do while turbo is out.

  3. WOW 5 Star Review

    Posted by on Jan 13th 2016

    Bought this to replace my stock turbo that seized after 13 years and 297,000 miles. Also bought the billet wheel to replace the stock wheel. This thing screams like there is no tomorrow. Paired up with EBPV delete pedestal, 4" exhaust and new intake my truck runs like a champ.

  4. Intake hose 4 Star Review

    Posted by on Dec 25th 2015

    Intake hose that is supplied is 1/2 inch too long other than that its a great product

  5. So far so good. Quick spool thankfully and not too loud. 5 Star Review

    Posted by on Nov 25th 2015

    After reading several reviews on this terrible I was worried it was going to be too noisy. It has been great noise level wise. I installed a wicked wheel two which was supposed to help spool time and noise levels. It has been great so far and I couldn't be more pleased.

    Riffraff shipped it immediately along with my International Up Pipes which are also great quality.

    Both of these products were high quality and a great addition to my 7.3.

    You won't regret purchasing either of these products from Riffraff.

  6. Worth it, 4 Star Review

    Posted by on Oct 31st 2015

    Excellent experience with Riffraff and a product that was what I was expecting. The 38r completed the other upgrades done to my 7.3. I now have a truck that pulls a heavy load with ease and is a blast to drive. No need to spend $60k on a new truck just to get a smogged out dog.

  7. Awesome Turbo 5 Star Review

    Posted by on Oct 9th 2015

    This thing is great spools super fast nice cool EGT's can't beat RiffRaff service or price !!!!

  8. Excellent upgrade from stock! 5 Star Review

    Posted by on Sep 28th 2015

    I bought this after deciding to do the EBPV delete, hoping that it would help with the light towing I do. With the stock turbo, something as simple as hauling my 17.5' bass boat would cause compressor surge and often times over-boost, kicking off cruise control. With stock injectors on a flash tune, I can tell a HUGE difference in performance not to mention the lovely sound we all like to hear from a turbo. :)

  9. Really enjoy this turbo!! 5 Star Review

    Posted by on Aug 26th 2015

    It was a straight forward installation and the addition of this turbo really took advantage of the 160/30% over sized injectors and the T500. These trucks should have come with this turbo from the factory. The quality is oustanding, and with my set-up, it's not laggy. The whistle and performance is intoxicating.

  10. Awesome upgrade and awesome service from Clay as usual! 5 Star Review

    Posted by on Aug 13th 2015

    Stock turbo quite literally blew apart, so my hand was forced. Already have 238/80 injectors in the truck, and with the tunes from Gearhead the 38R is a phenomenal upgrade. Quick to spool, smooth even power delivery, and of course that whistle! 6.0's have nothing on the sound it makes.

    Love love LOVE this turbo, absolute must if you're looking to upgrade your 7.3.

    As usual, huge shout out to Clay for his amazing service and always returning phone calls the same day!
