Radius Arm
Eliminate rear suspension flex, structural bowing, and costly trail snap-outs under heavy loads with premium replacement ATV and UTV radius arms. Rear suspension links undergo immense torsional strain when driving through deep ruts, slamming over rock ledges, or landing high-speed jumps. Stock radius rods are typically fabricated from thin, hollow steel tubing that easily bends when sliding over obstacles, permanently ruining your vehicle’s rear wheel alignment and destroying CV axles. At CG ATV & UTV Parts Shop, we provide ultra-rugged rear radius bars engineered from solid 6061-T6 aircraft-grade billet aluminum or heavy-walled chromoly steel tubing designed to slide right over jagged terrain without buckling.
Our streamlined domestic logistics infrastructure handles and picks our inventory with precision, delivering immediate order validation and rapid daily shipping directly to your maintenance shop. These upgraded trailing linkages feature high-clearance arched profiles to gain valuable ground clearance, heavy-duty adjustable Heim joints, and premium spherical bearings that eliminate weak rubber bushings. Correct your rear camber settings, stabilize your rear hub geometry, and conquer punishing trails with total peace of mind.

Suspension Engineering: Camber Alignment & Spherical Heim Joint Mechanics
An upgraded ATV and UTV radius arm linkage assembly offers distinct mechanical advantages over stock linkages by introducing true independent camber adjustments and high-articulation spherical Heim joints. Camber defines the inward or outward tilt angle of the rear tires; when factory linkages deform under heavy payloads or track impacts, excessive negative camber rapidly grinds down the inner tire tread and overextends CV joints. Heavy-duty adjustable radius links utilize left and right-hand threaded chromoly rod ends with machined flat spots, allowing technicians to dial in precision alignment settings without ever removing the bar from the mounting chassis tabs.
Furthermore, standard soft rubber bushings are replaced with teflon-lined, heat-treated spherical bearings. This structural change entirely eliminates suspension deflection and shifting rear-end play under heavy lateral load spikes, ensuring identical tracking parameters and firm throttle responsiveness during aggressive high-speed drifting and tight cornering maneuvers.

Alignment Specs, Torque Tolerances, & Maintenance Protocols
When installing a replacement set of adjustable radius rods, always use a solid reference point to verify that the center-to-center length matches your factory suspension layout perfectly before tightening down the locking jam nuts. Apply a high-grade blue thread-locking compound to all mounting hardware and utilize a calibrated torque wrench to secure the chassis bolts to factory specifications—typically ranging from 60 to 75 foot-pounds depending on your specific side-by-side or utility frame setup. For comprehensive engineering papers and design regulations outlining testing criteria for off-road structural components, review the publications curated by the SAE International Off-Road Vehicle Suspension & Linkage Standards Committees.
