The latest Ultra4 race of the season wrapped up last weekend in Jay, OK. The Visions Off-Road race was like no other – east meets west, double points, and a week of packed events for the whole family. Safe to say this was equal racing, equal vacation. Our friends over at Drivingline have a fantastic race recap that dropped yesterday, be sure to check that out. We’ll let them cover the recap. For this week’s post, I wanted to spend a little time on all these 4600 Broncos that seem to be dominating the Spidertrax Stock Class this season.

A few seasons back, our good friend & world-class racer Brad Lovell rang my cell. Of course, an out-of-the-blue call from Brad is nothing out of the ordinary. There’s always something going on in racing. However, this call had some big news, bigger than usual, and it needed to be kept quiet. While we all knew Ford was working on a new Bronco, thanks to plenty of spy photos and stories that leaked on the web, what wasn’t known was just how serious and intense the Ford Motor Company and the Ford Racing Team were treating this launch. They didn’t want to release just a sexy new machine, and yes, the new Bronco looks great. Instead, they wanted a machine that was an off-road powerhouse, and they knew they needed the best off-road racers in the world to make that happen.

Lucky for us, we get to work with the best off-road racers in the world. As I understood, my call with Brad was the first “off-road manufacturer” entry into the mix. The racers know what they want to see and who can make the things they need, and the most amazing part is that the Ford Racing Team supported the racers 100%. Playing an integral part in all things axle related, we worked across the field to select the best components while staying within the strict rules of the 4600 stock class. Dana rear ends, portal front axles, and Spidertrax Spider 9 Pro Series Hubs and Axle Shafts became part of a powerhouse of products and improvements to make this one of the best 4600 vehicles yet. I lost count of how many conference calls I enjoyed with all of the racers, engineers, planners, and marketing people. This project was, without question, the most intense and impressive race program I’ve ever worked on.

The final creation, the 4600 stock class Ford Broncos you have likely seen since the kick-off of this year’s King of the Hammers, is a force to be reckoned with. Race after race, the 4600 Ford Broncos (there are three in total) have dominated the field, and last weekend’s Vision’s Off-Road Race was no exception. Bailey Cole, Brad Lovell, and Vaughn Gittin Jr rounded out the Spidertrax Stock Class 4600 top three, and yes, these are your three Broncos in the Wild. Congratulations to all three drivers, not only for last weekend’s race but for the entire season to date. These Broncos are amazing machines, but these are the drivers that make it happen.

Next up in the 2022 Ultra4 Tour is an all-new Visions Off-Road Race in Jay, OK. Created as part of MidAmerica’s Off-Road programs, this double points, east meets west showdown, promises not to disappoint.

For those making to journey to Oklahoma, be sure to say hi. We’ll be there supporting race teams, showing off a few new products (like our brand new Sway Bars) from Levi’s Shirley’s base camp, and enjoying the racing. Best of luck to all racers, we look forward to seeing everyone out there, and for those unable to make the journey, keep an eye on live coverage by MOA.

A little history lesson to kick things off. Back in 2005, we created an all-new product category called The Spider 9®. This new performance axle swept the rock crawling and racing scene, winning more podium finishes than any other axle on the planet. They found their way into some of the most advanced lightweight US military-tactical vehicles. They even landed underneath the latest Batmobile. Things are good, we’re plenty busy, and we couldn’t be more grateful.

Good Engineers never sleep though and are always on a mission to make things better. For years, we’ve been asked to dive into sway bars. No specific direction was ever given, outside of the obvious – current sway bars are a mismatched hodge-podge mess of poor-quality parts. Sure, we can manufacture a quality product, but that alone is never enough. Could design improvements be made to a product category that is now decades old? Turns out, that answer is yes. We are thrilled to launch an all-new product category, the first since the release of the Spider 9®. Introducing our all-new Sway Bars. There’s a lot to uncover in this fresh take on an old product, so let’s dive right in.

7075-T6 Construction

There are a number of options on the market for sway bar arm material. Some of the most affordable versions are made of mild steel plates, not a terrible option when it comes to strength but the weight is less to be desired. Generally, these look rather awful as well. A few of the latest options are using 6061-T6 aluminum, a material you will find in our popular Wheel Spacer Kits. While a great wheel spacer material, the tensile strength of 6061-T6 is far from ideal for situations subject to high bending loads (such as the arm itself) and high fatigue (such as the splines). It machines great and is cost-effective, but outside of that, it wouldn’t be the first choice for a sway bar arm.

All of our Sway Bar Arms are machined out of billet 7075-T6. This unique blend of aluminum started its life in the 1940s, becoming a near-instant standard in high-performance aerospace applications. High tensile strength, good ductility, tough, fatigue-resistant – all at a fraction of the weight of steel. Often 7075-T6 is described as a material that is both as strong as steel and as light as aluminum, which in summary is quite accurate. With this improvement in material, the end result is one of the strongest Sway Bar Arms that is also manufactured as one piece. No messy bolt-on end tabs to assemble a rod end, used primarily to lower costs on manufacturing and aid in distributing loads on otherwise insufficient materials. Simple bolt your rod end directly to the Sway Bar Arm, and that is that.

Phased Splines

One of the most fun things about manufacturing all of your products in-house is balancing the challenges of innovated design and machining capability. One of the things we like least about current sway bar solutions is that once assembled, the arms themselves are always misaligned from each other. Few even talk about this anymore as it’s become such commonplace. No thank you!

The challenge we faced took the work of our entire team, from engineers to machinists, and the end result was well worth the effort. All of our Sway Bar Arms and Sway Bar Shafts are phased with each other. In sales terms, this simply means you assemble your complete Sway Bar and the Sway Bar Arms will be perfectly in-line with each other. Makes sense, looks great, and once you have it there’s no turning back.

In technical terms, we’re pulling this manufacturing feat off using a combination of two processes. First, all Sway Bar Shafts are phased from end to end. Meaning the splines on one end line up perfectly with the splines on the other end. Second, the Sway Bar Arms are phased per pair. So again, the splines on one arm line up perfectly with the splines on the other arm. That technical description is still a bit limited for my taste, but we can’t give away all of our manufacturing secrets!

Keep it Simple, Stupid

I’ve personally lost count of how many miscellaneous sway bar parts and bits I’ve seen lost on the field. More parts add complexity and pave the way for failure. Nearly all sway bar solutions in the market use the same old way of keeping the arms in place – pinch bolt, cover plate, and another bolt(s). Putting poor spline fitments aside (which leads to premature spline failure even with pinch bolts, but again putting that aside), sway bar arms are far from secure. The small cover plates easily come loose and once that happens, say goodbye to vehicle stability.

We decided to eliminate all of that and instead incorporated a pinch bolt that also locks itself into the Sway Bar Shaft. Inspired by the traditional pitman arm, this simple single bolt design provides superior clamping force (the bolt is closer to the shaft centerline) and a solid lock that is going nowhere (the bolt is keyed into the shaft notch). There should be no worry about the notch losing spline area either, we have plenty of total spline engagement, and using 7075-T6 provides all the spline strength we’ll ever need.

In Summary

We couldn’t be more proud of our Sway Bars, and we can’t wait for you to check them out in person. Thank you to the entire Spidertrax Team for many (many) months (years in fact) of hard work and dedication in making one of our best products yet. Please do not hesitate to reach out anytime to talk about how our Sway Bars will be a perfect fit for your next build, and of course, you can shop for your perfect Sway Bar by clicking here.

We’re no stranger to manufacturing a wide variety of off-road axle shafts. From the humble beginnings of the 26 spline Suzuki Samuari to the more modern 45 spline gun-drilled Ultra4 racer, if there’s a need for something stronger, something more capable, we’re in our comfort zone. So it would come as no surprise when rock crawling legend Tracy Jordan calls us up needing a portal axle shaft not yet invented, we’re full steam ahead.

Portal box axle shafts are traditionally designed around CV joints. There’s some good reason for that, many of these OE style applications depend on that constant velocity for rideability and handling. Moving over to the rock crawling world though, needs change. Serviceability, strength, and steering angle play a bigger role for those looking to tackle the planet’s toughest terrains. So, to take Tracy’s family build to the rock crawling level needed, we designed an end-to-end axle shaft solution to work flawlessly with his H1 Portal Boxes. Enter the Spidertrax Ultimate H1 Portal Axle.

We have designed, manufactured, and of course added to our online store, an axle shaft assembly to take your H1 Portal Box to the next level. Our billet one-piece stub shaft fits perfectly into an H1 Portal Box, with two inner axle shaft options to complement those popular housings & diffs — the Toyota 30 spline and the Ford 31 spline. Connecting the stub and inner axles is a specifically designed CTM 45 Series u-joint, sized like a 1350 OE joint, that completes the assembly. All said and done, this is the strongest, most serviceable, H1 portal axle shaft assembly that packs an unmatched 50° of steering.

The Batman, the highly anticipated “likely sequel” to Todd Phillips’ Joker, has been on our radar since 2019. The latest trailer above dropped this week, complete with an expected release date (March of next year), more gritty insight on other highly anticipated characters, and of course more teasing of the latest high-flying Batmobile. We figured why not wait till the movie is released to share a little more of the behind-the-scenes from our perspective, but these trailers have us so excited it’s hard to wait.

Spider 9 IFS drivetrain components are powering this latest trophy truck inspired Batmobile. While not our first time working with exotic movie builds, from the kid-favorite Monster Trucks to the highly reviewed Hobbs and Shaw, there’s something a bit different with this one. Maybe it’s the internet going crazy over these trailers, maybe it’s tied to my own childhood fascination with this particular superhero. Whatever the case, it’s a fun one to talk about and we are honored to be part of the story.
