I have a 2015 SLT Yukon SWB. Love it.. except the fact that it came with halogens and I went with Autoride instead of Soft Ride.. Well the second one is kind of a lie. I wanted Autoride.. but didn't realize that GM went into "Sports Car" mode when they designed it. Meaning that yes the Yukon handles damn near as nice as a Camaro, but the ride suffers once the air shocks pump all the way up to 10. The Lighting situation on the other hand is BULLSH!+!!! for a $70K vehicle.. especially when U get HIDs on a $30K Camaro. Anyway.. After talking with [email protected] I purchased the Beltech Springs and shock extender in an effort to fix my 'ride.." make it softer when hitting bumps. I did all the work myself but after changing all of that.. I ended up with a "Cadillac-ish ride" by modifying the Auto Ride Sensor Rods. Tony's kit came with a set, with recommendation of 3inches between connector to connector... I purchased 4 "rods" from Home Depot, screws actually, and cut them down using a hacksaw and a vice. I took it a step further by going down to 2.5inches. This lowered my vehicle too much.. causing me to cut a 10X24 machine screw to a length of 2.8 or 2 - 3/4. RIDE SO MUCH BETTER. Second... The lights. Just go on Amazon and look up MOSTPLUS 80W 8000LM 6000K CREE LED Headlight Kit Xenon White Bulbs (H8/H9/H11). . They are as bright as my CTS-V's.. and any other luxo brand I can think of. Cost me $50 and took me a blazing 10 minutes to install.
