INJORA 40g ProSteer Double Joint Front Axle for 1/24 Axial SCX24

In this review the INJORA 40g ProSteer double joint front axle is evaluated for small-scale trail rigs and 1/24 Axial SCX24 owners who want sharper turning and greater front-end control. The kit's CNC aluminum axle housing and steel steering links feel like an upgrade built for handling: the standout is the double joint shaft that noticeably reduces outside wheel vibration during hard cornering, which translates into faster, more precise steering and fewer twitchy recoveries on technical lines.

Key Features

• CNC aluminum axle housing: Provides durable, lightweight structure that resists flex and looks cleaner than stock plastic parts for long-term use.
• Double joint shaft design: Reduces outside front wheel vibration while cornering, improving steering speed and on-trail stability.
• Maximum 42 steering angle: Offers dramatically tighter turns compared with the stock 27, making tight rock sections and technical trails easier to navigate.
• +4mm extended axles: Increase vehicle stability over rough terrain and raise steering clearance to allow a wider selection of tires.
• 13T steel front gear (overdrive 23%): Shifts more drive to the front for improved pull, better climbs and a reduced tendency to rollover on steep approaches.
• Steel steering links and shaft: Improve durability where force is concentrated and help the kit install with minimal fuss on compatible SCX24 setups.

Who It's For

This axle is aimed at hobbyists running 1/24 Axial SCX24 models who want a clear handling upgrade: trail riders who value tighter turning radius, improved front traction and a sturdier front end will see the biggest gains. The unit suits builders who appreciate CNC metal parts and who may swap tires often to dial in performance.

It is not ideal for someone who needs full cross-compatibility with non-ProSteer axles, since the design is different and many parts are not interchangeable except for diff gears and the diff cover. Beginners who want a direct factory-spec replacement without any changes should consider staying with stock components.

Pros & Cons

Pros

• Improved steering precision and reduced wheel vibration thanks to the double joint shaft.
• Greater maneuverability from a 42 steering angle compared to the stock 27 angle.
• Durable construction with CNC aluminum housing and steel links for long-term use.
• Overdrive front gearing increases front pull and helps climbing performance.

Cons

• Proprietary design limits part compatibility with other axle types, so swaps are restricted.
• Some customers report occasional steering link breakage under heavy use, indicating a potential durability tradeoff in certain conditions.

Our Verdict

The INJORA 40g ProSteer front axle is a convincing upgrade for SCX24 owners who want sharper steering, more front traction and a tougher-looking metal front end. Its double joint design and increased steering angle make it good value for trail-focused hobbyists, but buyers should note limited compatibility with other axle families and occasional reports of steering link breakage under extreme use.

Frequently Asked Questions

Will this fit my Axial SCX24 without modification?
Many customers report bolt-on installation on standard SCX24s, but because the ProSteer design is unique some parts will not interchange with other axle types.

Does the kit increase rollover resistance?
Yes, the 13T front steel gear shifts more drive to the front and the extended axles improve stability, both helping to reduce rollovers during climbs.

Are replacement parts compatible with other axles?
The design differs from common axles, so parts are generally not compatible except for the diff gears and diff cover.
