Tech: Soften Your SCX10 II Suspension – For Free!

SoftenSCX10II_Suspension

Recently we walked you through an inexpensive way to lower the CG on your SCX10 II in our SCX10 II Handling Adjustment blog. With some hardware and a little time, the rigs handling was improved for those looking to get more performance out of their trucks. Now we have another suggestion to improve handling even more and this modification is completely free, as long as you don’t charge for your shop time. This modification is to soften the suspension on the SCX10 II and it’s done by just moving parts around that are already on the truck. The rear suspension has softer springs that will be moved to the front and medium rate springs to the rear. The shock positions will then be moved in the rear to give them a softer feel. It’s pretty simple, only requires a few tools and just a little bit of time.

TOOLS NEEDED
Kit Box Wrench
2mm Hex Driver

STEP 1
Axial Suspension 2
Like many steps in customizing your rig, step one here is to remove the wheels. First unscrew the “Locker” caps, followed by the 7mm wheel nuts using your box wrench.

STEP 2
Axial Suspension 3
Let’s start at the front and remove the lower shock mounting screw from the AR44 axle  with the 2mm hex driver. With the shock dangling, slip the spring perch off the bottom of the shock and remove the soft springs.

STEP 3
Axial Suspension 4
Now move to the rear of the machine and using your 2mm hex driver, remove the upper and lower shock mounting screws.

STEP 4
Axial Suspension 5
Here are the front medium rate springs next to the rear shocks. You can just see the difference in the springs thickness. You’ll want to remove the lower perches from the shocks and swap the springs.

Axial Suspension 6
The softer springs are now set on the rear shocks and ready for installation.

STEP 5
Axial Suspension 7
So the rear springs don’t roll off your workbench, now would be a great time to reinstall them back on the front shocks, slip the perches on and screw the lower shock mount back onto the AR44 axle.

STEP 6
Axial Suspension 9
Back to the rear of the rig. Start by removing the shock hoops front the frame. We’re going to take them off the one side and reinstall them on the opposite side in a bit.

STEP 7
Axial Suspension 10
Before reinstalling the shock hoops, the center cross brace needs to be moved. Take it from its stock location and push it forward to the forwardmost holes. This is where the new hoop locations will be.

The cross brace in the new location.

STEP 8
Axial Suspension 12
The shock hoops can be installed now. Remember, you have to swap the hoops from side to side.

Axial Suspension 13
Once the hoops are in the new position, you won’t even have to relocate the body mounts, they will be in the right factory location. Bonus!

STEP 9
Axial Suspension 14
Time to bolt the shocks back in place. Screw the top of the shock into the forwardmost hole.

STEP 10
Axial Suspension 15
Mount the lower shock mount to the AR44 axles. The shock will now be on a “lay down” angle. The angle of the shock gives the shocks a softer feel while it’s compressing, thus making it feel like it has a softer spring.

SEE THE DIFFERENCE
That modification was pretty simple and probably took you under ten minutes to complete. Now the trucks suspension will have a softer feel and allow it to compress as it goes over rocks and obstacles easier. Take a look at the difference below.

SCX10 II Handling Adjustment – $3 Shock Mod

We’re guessing by now you’ve logged a lot of miles on your SCX10 II ready to run rig. The truck has probably served you well tackling new terrain wherever your adventure takes you. So what’s next? How about improving your rig for better handling on those to tough to conquer trails. The stock out of the box SCX10 II is set up for general scale trail use, but the highly capable platform can improve as you improve and the tuning trick we’re about to show you will cost you just a few bucks and will take less than ten minutes of your time to complete. What we’re going to do here is lower the CG of the SCX10 II by simply relocating the lower shock mounting point. The shock end comes mounted to the axle on its own mounting boss. But, by relocating it to the same mounting point as the lower link, it lowers the overall Center Of Gravity of the chassis and a lower COG equals better handling. Let’s get started!

WHAT YOU NEED
axa120
3x25mm Button Head Machine Screw- AXA120
3mm Thin Nylon-Lock Nut- AXA1052 (Optional)
Basic hobby tools- 2.0mm hex driver, wheel nut wrench and long nose pleirs

Step 1
SCX Shock Mod 1
Let’s get the easy stuff out of the way. Remove the wheel nut caps, wheel nuts, wheels and lower shock mount screws from all four corners of your SCX10 II.

Step 2
SCX Shock Mod 2
Now, remove the screw that secures the link to the axle and place it in your spare hardware bin.

Step 3
SCX Shock Mod 3
Take the new long 3x25mm button head screw that you spent a whole $3 on and insert it through the shock end, into the axle mount with the link in place and screw it all the way in.

Step 4 (Option)
SCX Shock Mod 4
The screw will be secure as it has been screwed into the plastic axle mounting boss. But if you want to go one step further in security to make sure that screw doesn’t back out, you can add a thing 3mm Ny-Lock nut to the end of the screw. Tighten the nut snug.

Step 5
Repeat Step 2-4 for the remaining shock/ link points.

Step 6
Reinstall your wheels, nuts and caps.

SEE THE DIFFERENCE
SCX Shock Mod 6
You can see above, the left shock is in the stock location and the right shock has been relocated to the new position in-line with the lower link. The axle is also visibly lowered on the right side in the photo. Once all four shocks have been relocated and the truck turned upright, the chassis will now be lower in comparison to the stock position.

BACK TO THE TRAIL
Now you’re ready to head back out and try and navigate some of those tough terrain features that may have defeated you prior. With the lower CG, your rig will benefit from the modification. Keep in mind, this will not be a night and day difference. You still need to choose your lines and wheel speed wisely.
