Here is the final installment of my Ridgecrest crawler build, Stage 3. For this stage of the build I will be adding AR60 universals, aluminum shocks, under drive ring and pinion for rear axle, aluminum c-hubs, aluminum knuckles, aluminum lockouts, HD motor plate and a 55t motor. I will also be adding a few hop-ups from Vanquish Products as well. If you have never heard of Vanquish Products, check them out!! Their machine work and quality control is second to none. I will be adding a set of their DH wheels and titanium steering links to this build. So, let’s get started!!
The first hop-up I started with is the under drive ring and pinion for the rear axle. Adding the slower gear set to the rear axle will keep the front axle spinning faster in all situations. This will help with tight turns, and getting the front tires to pull up steep ledges. It can also help alleviate torque twist/chassis roll while on the throttle, which all shaft driven crawlers suffer from. The difference in the gearing between the front and rear after this modification is very slight, but it makes a pretty big difference. The old ring and pinion had a 13t pinion, with a 38t ring gear. This HD under drive combo has a 13t pinion and a 43t ring gear. It may sound like a big difference, but it really isn’t. Original ratio was 2.92:1. The new ratio for the rear axle is 3.30:1.
Make sure the axle shafts are pulled out of the differential assembly. Then you can remove the differential. I used a paper towel to wipe most of the grease away, makes working on the assembly a lot easier.
Now we can install the new 55t motor. I already installed the pinion gear onto the motor shaft. We just need to set the proper gear mesh and tighten everything down. The easiest way to set gear mesh is by inserting a small piece of paper between the spur gear and the pinion gear. Hold the two gears together with the paper in between and tighten your motor mount screws. Remove the paper and you should have a little bit of play between the two gears, which means you are good to go.
Here is a link that will give you some tips for proper build up of our competition shocks.
One change I made here was to use the rubber bushings that come with the new aluminum shocks in the shock cap, instead of the plastic ball studs. In order to keep the bushings in good working order, and free to move back and forth a little, I swapped the self tapping plastic screws for machined M3 flathead screws. The finer threads on the M3 screw shouldn’t tear the upper shock bushing like the stock self tapper would over time. I also went with a flathead screw over a buttonhead to let the upper shock cap pivot better as the suspension cycles.
Next we will address the front axle. I am going to install AR60 universals, aluminum c-hubs, aluminum knuckles and Vanquish Products titanium steering links.
Next we need to remove the inner axles. But, to get them out of the housing you will need to remove one screw from each lower shock/link mount. Removing those will allow the flange on the inner axles to slide out with out hanging up on the link mount screws.
Slide the new aluminum c-hubs into place. I clocked them back just a little to help with tight turns. Make sure the c-hubs are oriented correctly, the longer ear on the hubs should be on the bottom of the axle.
You will need the bearings, king pin sleeves and kingpin screws from the old knuckle/c-hub assembly. So, pull them apart and grab what you need to build the new knuckles up and bolt them into place on the c-hubs.
You will need to replace the old self tapping knuckle screws with 10mm long machined M3 screws. The stock knuckles were held in place by plastic self tapping screws, but you can’t use those screws in the new c-hubs as the hubs have a machined M3 thread in them. So, you will need some M3X10MM machined screws to complete this step. Part number for those is AXA115. There are 10 screws per package, so one pack is enough to do the job.
Next we need to bolt the tie rod arms onto the knuckles. But, you will need to swap the stock plastic self tappers for machined screws again. Luckily they are the same length as the kingpin screws from the previous step, and you will have some leftover to use here as well.
Now we will assemble the Vanquish tie rod and drag link. Pretty straight forward, thread the rod ends onto the linkage and pop the ball studs into place. You will have to fine tune the lengths of both the tie rod and the drag link once they are bolted up, in order to ensure the tires are straight and the servo horn has even throw to both sides.
Next I installed my Vanquish DH comp wheels. They are machined aluminum, and the weight of them alone should be sufficient in most situations. If I find the front is too light I will add some weighted slugs to the front wheels.
That wraps up Stage 3 of this Ridgecrest crawler build. I am going to try and shoot some video of this stage too, just to see/show the difference in performance over Stage 2. Stay tuned!!

Axial recently received the newest video production from Busted Knuckle Films called Rock Rods 3. It documents the “Rock Bouncing” craze that has taken over the 1:1 world in the southeastern US over the last few years. For those that haven’t heard the term “Rock Bouncing”, it is almost like rock crawling meets extreme hill climbing. And when I say extreme, I mean it! Most of the obstacles in this video are nothing short of brutal. All of the video footage was shot on privately owned land as well, so these are not your typical weekend trails. And your local trails are definitely not the place to hone your personal rock bouncing skills either, so please keep that in mind and tread lightly.
If you love the sound of built V8 engines roaring up to redline, the sound of expensive metal components colliding with rock and all around general carnage, this video is for you. The high speed action starts right away with the first chapter, and doesn’t let up for the entire 90 minute video. Highlights include a few south eastern competitions as well as some weekend trail run footage. Most of the rigs in Rock Rods 3 are sporting big block engines, heavily trussed one ton axles or 2 1/2 ton axles, overbuilt custom tube frames, hydraulic steering, huge custom cut tires, 4 wheel steer, etc. The video footage is creatively shot using multiple camera angles by some very brave cameramen who are constantly dodging flying rocks and debris. The drivers in this video are extremely talented as well using a combination of throttle and finesse to clear some jaw dropping obstacles. So, if you even remotely consider yourself a gearhead this video will not disappoint. Order up a copy for yourself, strap into your 4 point sofa harness and enjoy the wild ride that is to come!!

Dan found the Geocache on Oct 4th, his birthday, which was quite a long journey for him coming all the way from North Dakota. Way to go Dan!!!!!
Here is what he had to say about his adventure.
“I want to first say thanks to Axial for a great geocache! I recently saw your post on facebook that two of Axial’s geocaches were still out there to be found. I couldn’t believe that no one had found them yet! With my birthday coming up on October 4th, my wife and I decided to plan a trip to Cocoa Beach to look for cache #4. We flew from Minot, North Dakota to Miami (1950 miles) and drove up the coast (206 miles) to the cache spot. When we arrived at the coordinates, it was getting dark and had started to rain so hard that we had to take shelter. The lightening was intense and knocked out all lights in the area, so we decided to wait until the next morning, Oct. 4th (my birthday) to search again for the cache. We looked at the pictures on the blog page and were certain we were at the right spot. We got up early the next morning and headed back to the cache spot. After a few minutes of searching, I saw the green box. I could not believe I found it! Upon opening the box I was excited to find an XR10 kit. What an awesome birthday present!
I’ve been geocaching for years and have found numerous caches, but this was the best cache “booty” ever.
I regret that I was not able to bring my Wraith along for the ride, but will send pics of my crawler at home in North Dakota. My Wraith is pretty much stock except for a couple minor tweaks like Jamie Varner (MMA fighter) driving but I would like to customize it more in the future.
Thanks again for the adventure and the prize!”
Dan scored a complete Axial XR10 Rock Crawler… well almost complete, and some cool Axial swag only available to the Geocache finders. Dan, we are sending you the missing parts bags so you can assemble the kit.
