A little more power, a lot more sound, and a stance that completely changes the look.

With the DOD delete and performance upgrades complete, this 2018 Escalade was dropped on a Belltech 3/5 lowering kit to eliminate the factory rake and give it a lower, sportier stance.

Kooks headers and a Corsa cat-back make sure you can hear the difference, too.

FROM THE HUB.

404.7 WHP / 419.6 LB-FT

With a stock 2018 Escalade typically putting down around 340 WHP on our dyno, this combination picked up roughly 65 horsepower at the wheels while keeping all the comfort and usability you expect from an Escalade.

Not bad for the family hauler.

Getting ahead of a problem before it becomes a failure.

The owner of this 2018 Escalade was concerned about the well-known DOD lifter issues and wanted to add a little more power while we were in there.

We performed our DOD delete package with an upgraded camshaft, then added Kooks headers and a Corsa cat-back to let the new combination breathe.

Here’s a look at the process from the engine stand to getting everything back where it belongs.

Sometimes it doesn't take much to completely change the look of a truck.

This 2025 F-150 is a year-round daily driver, so the goal was to give it a sportier stance without sacrificing its ability to handle New England winters.

We dropped the rear 3" with UMI lowering shackles to eliminate the factory rake, then added 24x10 Vossen HFX6 wheels in bronze wrapped in General G-MAX tires. Gloss black Ford Performance fender bezels replaced the factory yellow accents, and the bedside decals were removed to clean things up.

A relatively simple combination, but a huge difference in the overall look.

KTR's favorite customer back with his third vehicle this year. This time, it's his 2025 F-150 daily driver.

A leveled-out stance, bronze Vossen HFX6s, General G-MAX tires, and a few carefully chosen appearance upgrades completely changed the personality of the truck without sacrificing its year-round usability.

We get to see some pretty serious combinations roll through KTR.

This C6 Z06 belongs to a professional race car driver who built much of his personal street car himself and brought it in to rent some time on our Mainline ProHub Dyno.

With a wild engine bay and over 1,100 horsepower at the wheels, there’s a lot to appreciate about this one.

Looking forward to seeing it back at KTR after the next round of upgrades.

FROM THE HUB.

1,116.7 WHP.

This C6 Z06 recently rolled into KTR for some dyno rental time, and it certainly made the most of it.

The owner built much of the car himself and worked with Tuned by Shawn to dial in the Haltech engine management system remotely, using our Mainline ProHub Dyno to put the combination through its paces at wide open throttle.

There’s still more left in it, too. Fuel supply became the limiting factor, so we’re looking forward to seeing this C6 back on the hubs after a fuel system upgrade to find out what the combination is really capable of.

Look what stopped by KTR for some time on the dyno.

This C6 Z06 has a serious combination under the hood.

Simple formula. Big transformation.

Whipple power, lowered suspension, upgraded brakes, and the right wheel and tire combination turned this regular cab shorty into a proper street truck.

These trucks respond incredibly well to the right combination of upgrades.

Another regular cab shorty F-150 in for one of our most popular combinations.

This 2016 came in as a mild-mannered pickup and left as a street performance truck with some attitude. A Whipple supercharger adds the power, while IHC suspension, upgraded brakes, and a fresh wheel and tire package completely transform the stance and driving experience.

It's a combination we've done on several of these trucks now, and for good reason. Whipple and IHC make great bolt-on packages that work extremely well on this platform.
