Lighting Tech Trends

When do you think the LED lighting fad is going to die out? I’m so tired of seeing all these trucks with LED strips and lightbars stuck all over them. It might have been cool a few years ago, but people need to get over putting LEDs on everything already.

First of all, we get where you’re coming from. Some guys really have gone into overkill mode with the number of LED lights on their trucks. Unless you’re driving a Baja trophy truck, it’s probably not necessary to put six huge LED lightbars on the front end. Besides, if you’re not careful, your truck ends up looking like one of those spaceships from Close Encounters of the Third Kind. It’s not ideal.

Then again, we have to disagree when you call LED lighting a fad. LED technology is the future of automotive lighting—no question about it. Why, you ask? It’s lightweight, compact, extremely reliable, generates minimal heat, and doesn’t require any fragile ballasts or bulbs. Oh, and best of all, it’s way more efficient from a power consumption standpoint, so there’s less drain on your electrical system. But don’t take our word for it—just look at all the manufacturers that have made the switch from HID projectors to LEDs recently.

So, to answer your question: LED technology isn’t going anywhere, although we do hope to see it applied more tastefully in the years to come. Thanks for writing!

Yukon Bonfire

I live in Southern California, and I recently saw a 2015 GMC Yukon burning to the ground on local news. According to the news anchor, it happened on a testdrive, when the truck suddenly shut off and started smoking, then burst into flames. I was thinking of buying a new Suburban, should I be concerned?

We also saw that story on the local news in SoCal. At this time, GM hasn’t said officially what happened in that instance, but we have a pretty good idea. Only a few days after it happened, GM issued a massive recall for 490,200 fullsize trucks and SUVs, including the ’14 Silverado and Sierra 1500, and ’15 Tahoe, Suburban, Yukon, and Yukon XL. According to GM’s statement, there is a “transmission oil cooler line that is not securely seated in its fitting” on trucks with six-speed transmissions. The company also said, “if the line is not securely seated and transmission oil leaks from the fitting, the oil could contact a hot surface and result in a vehicle fire.”

GM told the press this defect has led to at least three “incidents,” but no one has been injured. It’s more than likely that the Yukon fire you referred to was one of these three initial incidents. As far as buying a new Suburban, we can tell you that they’re very nice trucks and a huge improvement over the last generation. However, it might be wise to hold off a few weeks and see how GM handles this recall before buying.


When it comes to hateful comments on Facebook, we’ve certainly seen our fair share. It seems like no matter which type of trucks we post, there’s always someone looking to criticize them and start some drama. Most of the time, we ignore these comments, but sometimes we just can’t resist sneaking in a little smack talk—all in good fun, of course. Here are some of the comments we received—as well as our replies—after posting this ’bagged TopKick.

James Beattie: That ish is one of the most useless trucks I’ve seen...

Truckin Magazine: James, the owner actually uses this to tow his matching Tahoe on 28s, so it is far from useless. But thank you for your useless comment.

Mike Camarillo: I don’t think every truck needs to be lifted, but putting bags on this workhorse of a vehicle is pointless to me, and I’m entitled to my opinion just like everyone else. I can’t believe you guys get your panties in a bunch so easy especially since its not a picture of you or your vehicle.

Truckin Magazine: We don’t have our panties in a bunch. Just having some fun!

Ford recently unveiled its new medium-duty 2016 Ford F-650 and F-750, and we’d say it’s a pretty mean looking blend of 2015 F-150 and Super Duty styling. We’re sure someone with deep pockets will pick one up and modify it sooner or later, and we can’t wait to see the results. What kind of mods would you like to see done to this truck? Send us an email at and tell us your thoughts.

Hey Team Truckin, I really liked the “Rearend Renovation” story in Issue 5 of 2014, in which you rebuilt the axle on that Silverado. What I didn’t get is why you went with 3.73 gears. Seems a little conservative for a track-prepped truck…why not go with 4.10s or 4.56s?

Blue Bomber, the Silverado you’re referring to, is a track-ready truck as you said. However, the owner also uses it as a daily driver, so we wanted a gear ratio that worked well on both street and track. Going with a 3.73 ring and pinion allows his truck to maintain solid gas mileage and keep a low cruising rpm but also gives it plenty of punch off the line. If it was a track-only vehicle or we were using larger wheels and tires, going with a shorter rear gear ratio would make sense, but 3.73s are a good, happy medium.

Hey guys,
I’m thinking about putting a new exhaust on my 2003 Silverado 2500. It has the 6.0L gas motor. I know a lot of diesel guys run 4-inch exhaust pipes. What would happen if I ran a 4-inch pipe on my gas truck? Would it make more power, or is that overkill?

Brandon Micheau
Holland, Michigan Brandon,

It’s important to know that when it comes to exhaust pipes, bigger is not always better. If an exhaust pipe is too large, the exhaust gases slow down inside the pipe and cool off, and these cooler, denser gases won’t move as quickly out of your tailpipe. We could get more scientific and talk about backpressure and exhaust pulse frequency, but suffice it to say a huge exhaust pipe doesn’t necessarily mean more horsepower.

This is less true for diesel trucks, since turbochargers require larger exhaust diameters for higher flow and faster spooling. However, in the case of your naturally aspirated 6.0L gas motor, we’d say a 4-inch exhaust would be overkill and might even make your truck feel slower off the line. We suggest you stick with a 3-inch exhaust system, such as Corsa or Magnaflow.

• Engraved wheels... Love them or hate them? #truckporn #lowriderinspired #truckin #wheels @racelinewheels

• jerrydrztk: Why would you hate them? It’s called being different.

• n2trux: Cool to look at, but a bitch to clean. Not for this boy.

• trevor_joe: If you’ve got the money, might as well ball out haha.
