Vertex-10/Vertex-10W Weighted Outer Portal Covers (2) - RER43578
Pickup currently unavailable at 585 S Ferdon Blvd
Drop essential unsprung weight down where your crawler needs it most to stay planted on steep climbs and off-camber lines.
These Redcat weighted outer portal covers are designed specifically for the Vertex-10 and Vertex-10W portal axle platforms. By replacing stock covers with heavy brass portal covers directly at the wheel hubs, you dramatically lower your rig's center of gravity without loading up the suspension shocks or reducing articulation.
Why You'll Love It
- Low-CG Stability: Concentrates mass at the lowest physical point on the axle to keep your tires pinned and prevent roll-overs.
- Precision Factory Fit: Bolts directly onto Vertex-10 and Vertex-10W portal boxes with no trimming or custom modifications required.
- Unsprung Weight Advantage: Improves tire bite and traction over slick rock faces while keeping your chassis settled.
What's In The Box
- (2) Weighted Outer Portal Covers
Pro-Tip: If you are running a single pair, mount them on the front axle first to bias the chassis weight forward. This helps pull the front end up steep ledges instead of letting the front tires float.
