BMW 335i Radius arm bushings are the platform-specific polyurethane bushing kits used to replace worn rubber bushings at the front radius arm chassis and axle housing mount positions. The radius arm, also called a drag strut or tension rod on applicable platforms, connects the front axle housing or lower control arm to the chassis and resists the longitudinal forces generated by braking and acceleration, controlling fore and aft wheel movement and directly determining front caster geometry. On solid front axle platforms, the radius arm is the primary means by which the front axle is located longitudinally relative to the chassis, and the bushing at the chassis mounting position is the most geostandardally critical bushing in the front suspension.
As radius arm chassis bushings wear, increasing longitudinal compliance allows the front axle to move rearward under braking, contributing to brake dive, steering wander and the progressive front end instability that worn radius arm bushing compliance introduces under deceleration and cornering. On Applicable platforms that use a radius arm or tension rod to brace the front lower arm, worn chassis end bushings allow longitudinal arm movement that directly degrades front caster, steering response and alignment retention. The range covers radius arm to chassis bushing kits in multiple platform-specific configurations, radius arm to chassis mount bushing sets, a caster correction variant with caster shims, a performance specification kit, a front combined chassis bushing kit, a radius arm inner bushing set, a strut and control arm to chassis mount bushing set, and a tension rod caster correction bushing. All products are backed by a limited lifetime warranty.
Radius arm bushing wear on solid front axle trucks and 4WDs is a primary driver of the front end instability under braking that is one of the most recognizable symptoms of high-mileage solid axle suspension. The radius arm is the only longitudinal locating device for the front axle on these platforms, and the compliance at its chassis mount bushing directly determines how precisely that location is maintained under every braking and acceleration input. Worn BMW 335i bushings that allow the axle to move even a small amount rearward under braking introduce a measurable caster change that manifests as the characteristic steering pull and front end dive that solid axle trucks develop over time.
On Applicable platforms using a radius arm or tension rod at the front lower arm, worn bushings at the chassis end allow the arm to move longitudinally under load, degrading front caster and the alignment retention that correct caster provides. For lifted trucks where the radius arm geometry has already been displaced by the ride height change, a caster correction bushing with shims addresses both the bushing renewal and the caster error introduced by the lift in a single installation.
The BMW 335i radius arm bushing range includes:
BMW 335i Radius arm bushing renewal is the most direct and cost-effective repair for the front end instability, brake dive and steering wander that worn chassis mount compliance introduces on solid front axle platforms. Renewing the bushings restores correct longitudinal axle location under all braking and acceleration inputs, eliminating the compliance drift that allows front axle movement and returning confident, precise and stable front suspension behavior from the moment of installation.
For lifted trucks where the radius arm geometry has shifted beyond the factory caster range, the caster correction bushing with shim kit addresses both the worn bushing and the geometry error simultaneously, allowing the front end to be correctly aligned without requiring additional aftermarket correction hardware. For Applicable platforms where caster drift has resulted from age, wear or modification, the tension rod caster correction bushing delivers controlled inner pivot correction at the chassis mount position for a single-purchase geometry fix.
BMW 335i Radius arm bushing kits are designed for installation at the front radius arm chassis and axle housing mount positions on applicable platforms. Installation times range from under an hour for simple single position bushing kits to three hours for full chassis mount bushing set installations. Installation guides are available across most products. For additional technical assistance, a dedicated support team is available to confirm correct product selection, caster correction shim specification and fitment for the specific platform, lift height and arm configuration.
BMW 335i Radius arm bushings are manufactured from high-strength polyurethane engineered to withstand the longitudinal braking and acceleration loads, road shock and environmental exposure that radius arm chassis and axle housing mount positions are subject to in everyday, towing and off-road use. Geometry correction variants are precision-matched to deliver the correct caster correction for the applicable platform and lift combination, maintaining the set geometry under sustained driving loads once correctly installed and torqued. All products are backed by a limited lifetime warranty.
BMW 335i Radius arm bushings are a practical solution for:
The right radius arm bushing kit restores correct longitudinal arm compliance and caster stability at the chassis mount position, eliminates front axle movement under braking and acceleration, and delivers more precise, stable and controlled front suspension behavior through every braking and cornering input.
Explore the full BMW 335i radius arm bushings range and find the right kit for your vehicle. With radius arm to chassis bushing kits and mount bushing sets across applicable 4WD and passenger platforms, a caster correction bushing and shim kit for lifted solid axle applications, a performance chassis bushing kit, a combined front chassis bushing kit, radius arm inner bushing sets, strut and control arm to chassis mount bushing sets and a tension rod caster correction bushing, you can restore correct front arm longitudinal compliance and complete every radius arm bushing service with confidence.
