🔥 BSM Billet Knuckles – Development Update #2 🔥
Some people still believe that because the OEM knuckle is cast steel, aluminum could never compete.
We're here to show that great engineering isn't just about the material—it's about the design.
Months of engineering, simulation, and manufacturing have gone into creating what we believe is one of the most advanced billet front knuckle designs ever developed for the Honda/Acura platform.
DC2 • DC4 • DB8 • EG • EH • EJ
The latest machining update is here, and we're getting close! The majority of the CNC operations are now complete, with only three machining operations remaining before these move on to welding, final machining, inspection, and assembly.
This isn't simply another billet replacement for an OEM part. Every feature has been engineered with performance in mind.
âś… Integrated roll center correction âś… Suspension geometry correction âś… Modular serviceable design âś… Significant weight reduction compared to the OEM knuckle âś… Optimized for strength, stiffness, and motorsports use
While some existing designs focus primarily on replacing the factory casting, we chose to rethink the platform from the ground up—adding functionality and performance rather than simply changing the material.
The first production sets are getting closer every day, and we can't wait to share the next phase of development.
🔥 Built through endurance. Perfected through precision. Ready to change the game. 🔥
What you’re looking at is not just another billet part—it’s the result of serious development, engineering, testing, and vision coming to life at Blacksite Motorsports.
These BSM Billet Front Knuckles represent a huge step forward for the Honda and Acura performance world. Since the early 2000’s, when Moore Performance brought their legendary axle design to the scene, few have pushed billet front knuckle development at a production level. They were ahead of their time.
We believe we are RIGHT ON TIME.
The first 10 sets are now making their debut here at Blacksite Motorsports. Once CNC machining is complete, each set will be expertly welded by our team, then paired with ball joints, Centric bearings, and Karcepts hubs before heading out for pre-production release.
First applications include:
DC2 / DC4 / DB8 / EG / EH / EJ
These designs are configured to use OEM-height ball joints while delivering true geometry correction for lowered cars:
âś… +1.5" LCA / lower ball joint roll center correction âś… -1.5" UCA correction âś… Optimized steering arm height to help reduce bump steer âś… Improved handling and suspension response âś… Increased rigidity with reduced deflection under load
Built from Billet Aluminum, these knuckles are approximately 40% lighter than OEM, allowing for a faster-reacting suspension while providing a structure that is many times stronger and far more rigid than the factory design.
This is aerospace-inspired engineering, designed with one goal in mind:
To perform. To endure. To win.
The future of Honda and Acura suspension performance is taking shape right here.
At BSM, we do not build parts on hope, hype, or luck.
Nothing by Chance.
Blacksite Motorsports is getting closer to the official release of our BIG Spline Torsen CR-V Rear LSDs — and yes, they are here, tested, and proving exactly why we built them.
We have tested these units many times with great success, and they continue to show what the AWD Honda platform has needed for a long time: stronger engagement, better consistency, and a far more serious rear differential solution for builds that are done asking factory parts to do motorsports work. These units have been tested to 1600 HP with no failures and have also seen 7.47s in the 1/4-mile with Wanted Performance on their 1600 HP K-powered EG.
So no, this is not just another “upgrade” for people hoping stock parts survive real power. This is a proven solution for builders who expect the rear driveline to actually do its job.
Our BSM BIG Spline Torsen CR-V Rear LSD is designed around the Wagon 25-spline axle flange configuration, giving the CR-V rear differential a more capable spline arrangement for delivering more consistent power transfer than the standard CR-V setup.
BSM BIG Spline Torsen CR-V Rear LSD
Pre-launch units available by select inquiry
Expected pricing: $1050 + shipping
Limited quantities available for consideration before full release
Tested to 1600 HP with no failures
Seen 7.47s in the 1/4-mile
Designed for Wagon 25-spline axle flanges
Delivers more consistent power transfer than the standard CR-V setup
We are not announcing these as a full open public release just yet. However, we are willing to consider a select number of pre-launch sales for serious builders who understand what this part is, what it does, and where it belongs in a proper AWD Honda build.
For the AWD Honda crowd pushing real power, this is one of those parts that separates the people who say they are building AWD from the cars that actually hook, transfer, and survive.
Because at some point, the rear differential needs to stop being a passenger and start becoming part of the solution.
Billet AWD Parts Don’t Assemble Themselves… Unfortunately.
Another 3 Billet RT4WD Viscous Couplers are being staged for assembly at Blacksite Motorsports.
Seen here waiting on their remaining parts and components are the billet carrier bearings, which arrived yesterday courtesy of UPS. Today, the coupler bodies arrive with the shafts, input flanges, output flanges, and carrier bearing access doors.
And because apparently we like staying busy, this batch will be followed by 10 more RTAWD Viscous Couplers for CR-V differential assemblies.
Things are starting to pick up.
A few weeks ago, we also received the first of 10 new Torsen Big Spline CR-V LSDs — the same LSD platform used in the @Wantedbee 1600HP AWD Civic running 7.47s in the quarter-mile.
So yes… while some people are still debating whether Honda AWD works, we’re over here building the parts that prove it does.
Nothing By Chance.
Follow Blacksite Motorsports for the next stage of the build.
The difference between AWD that works and AWD that actually performs comes down to the differential.
The Blacksite Motorsports LLC RTAWD Torsen LSD is built for CR V, Element, and Crosstour platforms to eliminate wasted power and turn traction into real performance. Using a true gear driven torque sensing design, it instantly sends power to the wheel with grip, delivering smoother launches, stronger corner exits, and consistent control under load.
Engineered around a 25-spline wagon axle setup with a fully forged Torsen body and gear set, this is one of the strongest and most durable LSD options available. It is designed to outperform OEM solutions while supporting both standard and custom builds.
This same LSD design has already been proven in extreme conditions. Tested by Wanted Performance in their 1600HP K series Civic, it has gone 7.67 in the quarter mile, demonstrating real world strength and reliability at the highest level.
Compatible with 1st, 2nd, and 3rd gen RTAWD differentials, this is what completes an AWD build and makes it perform the way it should.
Inside the Blacksite Motorsports RTAWD CR-V Viscous Coupler.
This is the RTAWD Internal Hydraulic Viscous Coupler, a fluid-filled hydraulic damper designed to manage torque transfer between front and rear under load.
This coupler uses shear load of viscous fluid to engage power transfer to the rear, instead of the OEM clutch design that relies on wheel speed variance between front and rear to hydraulically engage clutches. This creates smooth and consistent power transfer from the transfer case to the rear differential to the rear wheels.
Nothing By Chance.
Follow to learn what really happens inside the Blacksite Motorsports RTAWD system.
Most people see the Honda Dual Pump Assembly as just another part. At Blacksite Motorsports, we see it for what it really is. An advanced torque management system that was ahead of its time.
Inside this system, primary and secondary oil pumps work together to generate pressure from wheel speed differences driving a piston that applies load to the clutch pack and transfers power to the rear.
We adapted this pump for motorsports with refined internal changes and shimming strategies to control pump pressure. The primary pump housing acts as a pressure differential system balancing output from both pump gears to force pressure build up and engage the dual pump piston which then applies the clutches and sends power through the carrier to the rear wheels.
Every component from the gears to the housings to the sealing surfaces plays a role in how that power is delivered. This is where real engineering happens and where performance is either gained or lost.
This design builds on our previous innovations refining how these systems operate under load to deliver more consistent and controlled AWD performance.
This isn’t just a viscous coupler it’s a complete AWD solution.
Our RT4WD Billet Viscous Coupler has been proven across both Honda and Mitsubishi AWD platforms delivering controlled power transfer where it actually matters.
Everything you see comes in the box. 79 viscous plates, 38 centering rings, coupler shaft, CV joint delete, carrier bearings and mounts, and no cut flanges designed to accept our 1310 billet driveshaft system. Built using OEM bearings and snap rings just like the factory intended.
This is how you take an OEM concept and evolve it into something capable of real performance without compromise.
