Fits:
2014–2026 Ram 2500 4wd
2014–2026 Ram 3500 4wd
Important Fitment Details:
- Designed to accommodate up to a 305/65 tire on a factory 20” wheel. Actual tire clearance may vary based on tire manufacturer, wheel specifications, suspension height, and vehicle configuration.
- These Radius Arms do not change ride height.
Features:
-
Fully Boxed Radius Arm Construction – Heavy-duty boxed design significantly increases strength and rigidity over the factory radius arms while reducing unwanted suspension deflection.
-
Heavy-Duty A36 Steel Construction – Engineered to withstand the demands of heavy trucks, towing, off-road use, and oversized tires.
-
Double-Shear Axle Mounting – Captures the axle-side mounting point from both sides for increased strength and secure suspension control under extreme loads.
-
Integrated Tire Clearance – Purpose-built arm profile provides additional clearance for oversized tires, accommodating up to a 305/65 tire on a factory 20” wheel.
-
Retains OEM Caster Eccentric – Maintains the factory-style cam adjustment for simple, precise caster correction and proper alignment.
-
Vulcanized Rubber Bushings – Heavy-duty bushings provide long service life while isolating unwanted noise, vibration, and harshness.
-
Improved Front-End Stability – Increased radius arm rigidity helps maintain axle control for more predictable handling and improved steering stability.
-
Durable Black Powder Coat Finish – Provides long-lasting corrosion protection against harsh weather, road debris, and off-road environments.
-
Direct Bolt-On Installation – Engineered to replace the factory radius arms without cutting, welding, or fabrication.
Description:
The Kryptonite Death Grip Radius Arm Kit is engineered to take control of the front axle on 2014–2026 Ram 2500 and 3500 4wd trucks. Replacing the factory radius arms with a substantially stronger, fully boxed design increases suspension rigidity and axle control while providing the clearance and alignment capability needed for modified heavy-duty Rams.
Constructed from heavy-duty A36 steel, each radius arm features a fully boxed and welded structure designed to resist the flex and deflection that can occur under heavy loads, aggressive driving, and off-road use. At the axle, a double-shear mounting design captures the mounting point from both sides for increased strength and more secure control of the front axle.
An integrated tire clearance is built directly into the arm profile, providing additional room for oversized tires without compromising the strength of the radius arm. The design accommodates up to a 305/65 tire on a factory 20” wheel, making it an ideal upgrade for trucks running larger tire combinations.
Rather than introducing unnecessary alignment hardware, Kryptonite retains the factory cam eccentric caster adjustment. This provides a wide, easy-to-adjust range for dialing in proper caster and achieving the alignment specifications necessary for predictable steering, straight-line stability, and confident drivability.
Heavy-duty vulcanized rubber bushings provide secure axle location while helping isolate road noise, vibration, and harshness. Combined with the increased rigidity of the boxed arms, the result is a front suspension that feels more controlled and planted without sacrificing the characteristics expected from a street-driven heavy-duty truck.
Finished in a durable black powder coat and designed as a direct bolt-on replacement, the Kryptonite Death Grip Radius Arm Kit delivers the strength, clearance, and axle control needed for everything from daily driving and towing to demanding off-road use.
