LEGO 42126 V-8 4×4

Sometimes a LEGO set needs just a little more content. 42126 is one of them.
Instructions may be found on Rebrickable.com.
LEGO 42126 was introduced in the Summer of 2021, and I was immediately drawn to the pickup as it included some features I like, such as steering, suspension, a decent (at least in the USA) price, and it’s Orange! But there were serious features lacking such as four wheel drive, a V-8 (I know, I know, a Raptor, and many of Ford’s F-150s use a turbo V-6), and the rear suspension geometry was weird. I agree with others, that some parts of the design like the rear taillights and the front headlights are a little off. But, like 8081, I saw some potential here, and I ordered the set.
In fact, before I even received my copy of 42126, I was designing and a building a new chassis. The V-8 was easy enough to add, as the space under the hood is extensive. Adding in a front drive axle was a little more complicated. To keep the width, steering geometry, and suspension travel the same as 42126, adding a front drive axle would take a little work. I used a floating differential design, which allows the differential to move freely as the suspension travels through its movement. The steering link was flipped upside down, and relocated in front of the drive axle. The suspension swingarm and shock absorber mounds did not change.
Immediately behind the engine firewall a differential that connects to the V-8, and the rear axle. The rear axle is changed to replicate a better movement of the rear Raptor. LEGO noted how the half module offset of 42126 was a feature they had to work on to get the placement of the axle correct. However, this feature was only needed as the pivot point of the rear axle was so to the rear of the pickup. By moving the pivot point of the rear axle farther forward, the travel pivots less, and creates a better axle movement of more up and down. This also helps place the axle better when one side is up, and the other down.
While I made no changes to the exterior, I made minor changes to the interor. The colors of the seats have been changed so they match one another a little better. Finally, with a little bit of cross frame bracing, the pickup was done. When 42126 finally arrived, I removed the bed, the doors, the hood, and the roof from 42126, and my F-150 was done.
I like making modifications of sets more than I like making B or C models of them. As such, this project was an enjoyable one for me. I worked fast, and I liked the improvements I was able to make to the original. I like the look of 42126, so keeping this consistent was fine for me, and the additions of the V-8 and the four wheel drive was a fun challenge to pursue. Now to see if I can do a Sport Truck version of 42126. Stay tuned….
Happy building!
