ReadyLIFT Tubular Radius Arms

 

ReadyLIFT Tubular Radius Arms give lifted solid-axle trucks a stronger, purpose-built connection between the front axle and frame. Radius arms control fore-and-aft axle movement and play a major role in caster, braking stability, and suspension articulation. Replacing the factory arms with application-specific tubular assemblies helps support the revised geometry and increased loads that come with a suspension lift and larger tires.

Correct radius-arm geometry helps the front axle remain planted while the suspension moves through bumps, braking, and off-road articulation. The arms are designed to maintain a useful caster relationship within the supported lift range, improving steering return and straight-line tracking. Customers gain a front end that feels more deliberate without giving up the suspension movement needed for rough roads and trails.

High-strength steel tubing and reinforced mounting points provide the rigidity required by a heavy-duty truck. The tubular form creates a strong structural path between the axle and chassis while allowing application-specific clearance around driveline and suspension components. A durable powder-coated finish helps protect the arms from road spray, debris, and routine underbody exposure.

Bushing or joint designs vary by the selected truck platform, but each system is intended to manage axle movement with less unwanted bind than an incorrectly positioned factory arm. The correct arm length and mounting geometry are critical because they influence caster, wheelbase position, and suspension travel. ReadyLIFT arms are therefore matched to specific lift systems and vehicle layouts rather than treated as universal replacements.

Radius arms work as part of a complete front suspension package that can also include springs, shocks, track-bar correction, pitman-arm or steering components, brake-line provisions, and alignment adjustments. Customers should verify that every component is compatible before installation. Worn axle bushings, damaged mounts, or incorrect lift brackets should be corrected at the same time.

For tow rigs, work trucks, daily drivers, and trail-focused heavy-duty builds, stronger radius arms support both control and durability. They help the axle respond predictably under braking, steering, and articulation while giving the suspension a clean upgraded appearance. Whether customers are upgrading for corrected caster, stronger axle control, or improved lifted suspension articulation, ReadyLIFT Tubular Radius Arms deliver a robust front suspension foundation.

Why Choose

This product is ideal for customers who want stronger front axle control, supported caster geometry, and durable tubular construction for a lifted heavy-duty truck.

• Purpose-built arm length and geometry match the supported truck and lift system
• Tubular steel construction creates a rigid link between the axle and chassis
• Helps the front axle remain controlled during braking and rough-road movement
• Supports steadier steering and tracking when caster is correctly set
• Application-specific clearance accommodates the surrounding suspension and driveline layout
• Durable finish protects the arms in an exposed underbody location
• Useful for trucks that tow, haul, commute, or travel off-road with larger tires
• Completes a suspension system with upgraded structural components rather than ride height alone

Installation Notes

• Confirm vehicle, axle type, engine and drivetrain requirements, lift height, and suspension-system compatibility before installation.
• Professional installation and a complete alignment are required because radius arms affect axle position and caster.
• Inspect factory frame mounts, axle mounts, bushings, track bar, steering linkage, brake lines, and driveshaft clearance before installation.
• Verify caster, wheelbase position, fastener torque, brake-line routing, and clearance through full steering and suspension travel afterward.

Buyer is responsible for use in accordance with applicable vehicle, road, off-road, towing, racing, and local laws.

Warranty Information

ReadyLIFT's No Hassle product warranty applies to the original purchaser and covers eligible missing or defective components. Proof of purchase may be required, and replacement-part handling follows ReadyLIFT's current warranty procedures.

Warranty coverage does not extend to improper installation, incorrect application, abuse, collision damage, unauthorized modification, neglected maintenance, or damage caused by use outside the product's intended suspension or steering setup. Wearable components can carry shorter coverage periods, so customers should retain purchase records and follow all inspection and service requirements.
