Overview
Add low-mounted weight, durability, and improved crawling stability with the Power Hobby Brass Front and Rear Portal Axle Housings Set. Designed as a performance upgrade for the Redcat Ascent-18, these housings replace stock components with solid brass construction, lowering the center of gravity and enhancing traction on steep climbs and off-camber terrain.
By adding weight directly at the axles — the most effective place to add mass on a crawler — this upgrade helps keep tires planted, reduces chassis roll, and improves overall control during technical crawling. The result is a more confident, planted feel that pays off on every line.
Key Features
- Solid brass construction adds low-centered weight for improved stability
- Front and rear set delivers balanced weight distribution
- Direct upgrade for Redcat Ascent-18 portal axles
- Precision machined for smooth gear operation and reliability
- Increases durability over stock plastic housings
Performance Benefits
Installing brass portal axle housings shifts weight downward where it's most effective. This increases tire contact, improves side-hill confidence, and helps prevent rollovers when navigating uneven or vertical terrain — making it a must-have upgrade for serious 1/18 scale crawlers.
Usage Notes
Best for technical rock crawling and trail use on the Redcat Ascent-18. Increases vehicle weight, which is desirable for crawling but may slightly reduce top speed and runtime. Verify gear mesh after installation.
