  1. If you have a 3.08 axle ratio, changing to a 3.42 or a 3.73 will make it much faster accelerating and make a considerable difference in towing ability.
  2. GM must use different wiper blade suppliers. I have never found a blade that would last as long as the original ones on my 2015 Silverado, built at Flint. I hate the adapters and find them inferior to direct fit blades. I have used Bosh Icons and they were average life. I am now using Trico direct fit, they work good an are quiet. I wonder how long these will last?
  3. The only time I remove mine is when I go the dealer for a recall. Onstar has never detected it. 2015 Silverado
  4. I have a 2015 Silverado LT Z71 4wd. I am using the KYB Gas-A-Just mono tube struts and shocks. These are their heaver duty shocks and give a firm but not harsh ride. I would recommend them.
  5. I got rid of my SRA tires at 35k miles for the same reason. I now have Michelin Defender 265-65 18 tires and have excellent wet traction on my 2015 Silverado LT Z71 crew cab.
  6. I have a 5.3, 6 speed with the 3.42 axle, it tows a car trailer just fine on regular fuel. I would not buy one with the 3.08 axle, because it has a 2000 lb lower tow rating.
  7. The Range plugs into the diagnostic connector under the dash and blocks the signal to run on four cylinders. The difference in mileage is not that much. The elite catch can catches oil vapor in the PCV system before it can deposit on the intake valves. There is no good way to prove that these modifications are beneficial without disassembling the engine. It is my belief that it better to be safe than sorry later. When I went to the dealer for warranty work, I temporarily removed both of them and the dealer never knew that the truck had been modified.
  8. I have done it every 10k miles on my 15 Silverado. Follow the instructions carefully. I sprayed it into the PCV fitting on the intake manifold. Sometimes it might run a little rough for the first few minutes after the procedure. I now have 50k miles and the truck runs great and uses almost no oil. I use Mobil 1 0W20 and change it at 5000 miles. I have a Range and an Elite catch can. Th Elite collects about 1 ounce of fluid every 1000 miles.
  9. 2015 Silverado LT Z71

    low beam: Fahren H11 60 watt,10k luman, 6500 k cool white, $39.99 a pair on Amazon. Great improvement over stock.

    Fog and driving bulbs: Alla Lighting 8000 lumen, 5201-5202 LED Switchback bulbs, $49.99 per pair on Amazon. These switch from white to amber by pushing the fog lamp switch.  Great driving lights when on low beam. I have not tried them in the fog. I have tried the Morimoto fog lamps and found them inferior to the above described bulbs.  I will sell the Morimoto's for a reduced price (used one week.)

  10. I am using KYB struts on my 2015 Z71 with Michelin Defender P265-65 -18 tires and have a good ride and handling. I once put Bilstein shocks on a 3500 Chevy van and got the hardest ride of any truck I have driven.
  11. My 2015 Silverado 1500 4x4 LT Z71, 5.3, 6 speed, 3.42 axle crew cab, runs flawlessly on 87 octane Top Tier fuel. I have tried 89 with no change in performance or mileage. Note: I am using a Range and an Elite catch can. I had no issues before making these changes. I do a CRC GDI intake cleaning every 10 k miles also. I now have 45k miles and use no oil between 5000 oil changes (Mobil 1 0W20 ) I wonder why others are having issues with a 5.3 and 87?
  12. December 7, 2019 - I still have not seen a single one on the road in Oregon. Dave, Portland
  13. I live in Portland, Oregon and have yet to see a 4500, 5500 or 6500 truck. Dropping the mediums in 2009 was one of GM's stupidest moves ever. I think dealers and former customers are still pissed off and are going to continue buying Fords. Dave, a long time GM customer
  14. The fog lights on my 2015 Silverado LT Z71 are basically, worthless even after converting them to LED bulbs. My headlights were really bad until I converted them to LEDS. The LED low beam headlights work better in the fog than the fog lights. Before spending the money for fog lights, I recommend you drive a fog light equipped truck and see if you think it is worth it.

  15. I tried NAPA Adaptive One pads on my 2015 Silverado Z71 and they put out a lot of dust on my wheels. I took them back to NAPA. I now have Akebono Proact ceramic pads. No dust, quiet, smooth. Akebono is an oem GM supplier made in the USA. The Adaptive Ones were made in China. (The Adaptive Ones on my Buick Lucerne have not had a dust issue)
