The INJORA 40mm Big Bore Oil Shocks are a performance suspension upgrade designed for 1/24 scale RC crawlers, including the Axial SCX24 and FMS FCX24M. Featuring CNC-machined aluminum construction, adjustable spring preload, and weighted brass lower rod ends, these shocks provide improved suspension tuning and added stability for technical rock crawling.
Unlike traditional friction-style shocks, the INJORA Big Bore shocks utilize oil lubrication and internal bladder seals to promote smooth suspension movement and consistent rebound. Their larger-diameter shock bodies accommodate oil lubrication, helping reduce friction during suspension compression and extension.
The black aluminum shock bodies feature threaded preload adjustment collars, allowing users to fine-tune spring tension to match their vehicle's weight and driving conditions. Two spring rates are included for additional suspension customization.
The brass lower rod ends add weight near the bottom of the suspension, helping lower the vehicle's center of gravity and improve balance on steep climbs, sidehills, and uneven terrain.
40mm Big Bore Design: Larger-diameter shock bodies provide smooth suspension movement and improved tuning capabilities.
CNC-Machined Aluminum Construction: Precision-machined shock caps, bodies, and lower caps provide durability.
Brass Lower Rod Ends: Adds weight low on the vehicle to help improve stability and crawling performance.
Oil-Lubricated Operation: Uses shock oil to reduce internal friction and promote smooth suspension action.
Internal Bladder Seals: Designed to provide consistent rebound and suspension movement.
Threaded Preload Adjustment: Adjustable collars allow quick changes to spring preload.
Two Spring Rates: Includes optional springs for customizing suspension performance.
Black Electroplated Steel Shafts: Durable shock shafts provide smooth operation and resistance to wear.
9mm Maximum Travel: Allows suspension movement for navigating uneven terrain and obstacles.
Black and Brass Finish: Combines black aluminum shock bodies with weighted brass lower ends.
Complete Four-Shock Set: Includes four shocks for upgrading the front and rear suspension.

Remove the factory shocks and install the INJORA Big Bore shocks using the appropriate mounting hardware. Adjust the threaded preload collars to achieve the desired suspension setup, and use the included optional springs to fine-tune the vehicle's handling.
For proper lubrication, apply only enough shock oil to create a heavy coating on the internal components. Compress and cycle the shocks to distribute the oil evenly.
Important: Do not completely fill the shock bodies with oil. These shocks are designed for light oil lubrication rather than conventional fully filled hydraulic damping. Shock oil is not included.
Note: Verify compatibility with your vehicle's suspension mounting points, chassis configuration, and available clearance before installation. Vehicle and shock oil are sold separately. Recommended for ages 14 and older.
