BP Custom SCX10 II AR44 Servo on Axle Mount
About this part
The BPC SCX10 II AR44 Servo on Axle Mount gives competition oriented drivers a SOA option for the AR44 housing. This stainless steel mount adds 30 grams of weight to the axle housing. Longer link mount screws are required for installation. Made in the U.S.A.
NOTE:
- BPC components are designed for builders. Modification to these parts and/or your existing parts may be required to work with your application.
- Longer M2.6 link mount screws are required for installation. We recommend you use a 2.6x16mm length screw, and cut the screw down to the appropriate length.
- Requires servo mounts to attach the servo to the BP Custom mount.

This mount is awesome. As another reviewer mentioned, there are two styles. The more square looking mount (BPCSM2) fits the multi-piece AR44 axle by mounting with the removable link mount holes. The more slender looking mount (BPCSM2RTR) fits the single piece AR44 axles with built in truss. These are the axles that came on my SCX10II Deadbolt, and presumably other RTR SCX10II models, though make sure you check your truck. If you have an RTR, you can pick up the Axial AR44 Complete Locked Axle Set (AXI31438) and use the BPCSM2 mount. This adds $80 to the cost of the SOA upgrade, but then allows you to run metal C-hub carriers, knuckles, and link mounts. Even if you aren't going to run aftermarket metal parts, the Axial AXI31438 kit let's you fix broken C-hub carriers and/or knuckles without replacing the entire axle. As far as the actual SOA conversion/installation process goes, it fits well and mounts securely. As the other reviewer mentioned, you will need to buy/fabricate a custom drag link. Also, as is mentioned in the description, you will need to get a pair of servo mounts to complete the conversion. The suggested mounts were out of stock, so I went with the some mounts from ST Racing that were meant for the DR10 (SPTSTC91391SBK) and they fit great. Some other SCX10II SOA conversions have the servo mount built in, but I like that this leaves the option to use brass or steel servo mounts for added unsprung, non-rotational weight. You will need a second upper link mount to convert to a 4-link setup. My Deadbolt RTR had one of the plastic links in the extra parts trees and the other reviewer mentioned the builders kit having one as well. Be aware that standard metal link kits for the SCX10II will not have a fourth link for the front, so you'll need to either fabricate or purchase a link kit that is specifically four link front if all plastic links aren't your thing. Lastly, on the BPCSM2, you'll need four 2.6x16 bolts to replace the factory link mount hardware. I suggest TRA2618, as 2.5mm worked fine for me, if you don't have any 2.5/2.6mm bolts long enough. All in all, a great conversion that allows for a much smoother, cleaner suspension setup that doesn't feel like the panhard and drag link are fighting each other constantly like out of the box
I think it is the best option to mount the servo on the shaft, it fits well and no screws protrude. I will cut the two front bottom screws
Does not work with AR44 one piece axle housing as it appears to bolt on where the screws attach the lower shock mounts to the axle. The one piece housing has the lower shock mounts molded into the housing. I’ll hold onto it since I’m planning on building a lcg build with a Gspeed chassis kit and AR44 axles. Part is no nonsense and well built and should do it’s job well.
Great quality and really strong servo mount! And add some weight on front axle ??
Be wary of what axle you are using. It does not universal fit with all available aftermarket axles
Reviewers generally rate the mount well made and strong, with a secure fit and no protruding screws in one installation. The main recurring issue is axle compatibility: the mount fits multi-piece AR44 axles but does not fit one-piece AR44 housings where the lower shock mounts are molded in, and one reviewer found it does not universally fit aftermarket axles. One review refers to two mount styles (a square version for multi-piece axles and a slender version for single-piece truss axles, as found on some RTR SCX10 II models), which suggests buyers should check their axle type before ordering. One reviewer noted that cutting the front bottom screws may be needed for a clean fit, and another asked whether the mount adds front-axle weight, which is not answered in the reviews.
