Quick answer
The Vanquish Currie F9 portal rear axle is a strong, adjustable upgrade for your Axial Capra, offering better clearance and suspension tuning—ideal if you're pushing your rig on technical trails.
Why upgrade the Capra rear axle?
The stock Capra axle works for many, but serious crawlers often want more durability, ground clearance, and tuning options. The Currie F9 addresses these with a machined aluminum housing and adjustable upper link positions.
Portal axles raise the axle centerline, which increases ground clearance under the differential. This can help you clear rocks and ledges that would otherwise hang up a straight axle.
Trade-offs to consider
Portal axles add rotating mass and can slightly increase drivetrain friction. For most trail rigs the clearance benefit outweighs this, but pure speed-oriented builds might prefer a lighter straight axle.
The F9 axle is a significant investment (catalog price USD 169.50, compared to USD 252.99). It's a premium part aimed at enthusiasts who already have a capable chassis and electronics.
Decision rules for the Currie F9 rear axle
- Ground clearance need: If your Capra frequently drags its axle housing on rocks, the portal design of the F9 will give you noticeably more clearance under the diff.
- Suspension tuning desire: The adjustable upper link positions let you change geometry without buying new links. This is useful if you experiment with ride height or shock angles.
- Budget and build level: At USD 169.50, this axle is for intermediate to advanced builders. If you're still running stock electronics or plastic links, consider upgrading those first. Prioritize drivetrain and steering upgrades before the axle if your budget is tight.
