Trailing Arm Kits for Vehicle

Trailing arm kits are complete rear trailing arm assemblies used to replace worn, bent, structurally compromised or geometry-deficient rear trailing arms. The rear trailing arm is the primary longitudinal locating link at the rear wheel position on applicable multi-link and semi-trailing arm rear suspension platforms, controlling fore-aft wheel position under braking and acceleration, defining the rear toe geometry arc through its pivot axis angle, and carrying the lateral and longitudinal suspension loads generated at each rear wheel during cornering, braking and acceleration. The condition of the arm structure and inner pivot bushings together determines how precisely and consistently the rear wheel is located under load.

Where bushing-only kits address inner pivot compliance within an existing arm, a complete trailing arm assembly renews both the arm structure and its pivot interfaces simultaneously. The correct solution when the arm itself requires replacement rather than bushing service alone. The range covers a rear trailing arm set for applicable RWD performance platforms and an HD adjustable rear lower trailing arm set for applicable performance and 4WD platforms requiring rear geometry correction through an adjustable inner pivot.

Why Upgrade Suspension?

Rear trailing arm replacement is the correct repair when the existing arm has been bent or cracked by a hard impact or kerb strike, when corrosion has compromised the arm structure or inner bore condition, or when the factory arm geometry limits the rear geometry correction available at the lower trailing arm position. on applicable RWD performance platforms where the rear suspension geometry directly determines rear handling balance and stability under hard cornering and braking, a structurally compromised or geometrically deficient trailing arm affects rear toe consistency and rear wheel location in a way that bushing renewal alone cannot address.

For performance and modified applications on applicable platforms where rear camber and toe geometry correction is required beyond what the factory arm geometry allows, whether from a ride height change, a track use requirement or a specific alignment target, an HD adjustable rear lower trailing arm with an adjustable inner pivot delivers the correction range and structural specification that factory arms and standard replacement arms cannot provide.

Trailing Arm Kit Range

The trailing arm kit range includes:

• Rear Trailing Arm Sets: Complete rear trailing arm sets for applicable RWD performance platforms, supplying both left and right rear trailing arms as a matched set for simultaneous renewal at both rear positions.
• HD Adjustable Rear Lower Trailing Arm Sets: Heavy duty rear lower trailing arm sets with an adjustable inner pivot for applicable performance and 4WD platforms, providing a continuous range of rear geometry correction at the lower trailing arm position to achieve rear camber and toe settings beyond the factory arm's available range.

Why Purchase Trailing Arm Kits?

A complete trailing arm assembly is the appropriate repair path when the arm structure itself requires replacement rather than bushing renewal alone. For worn, bent or corroded arms where the structural condition of the arm body or its inner bore is compromised, renewing only the bushings leaves the underlying arm condition unaddressed and the rear wheel location dependent on an arm that cannot be returned to correct structural specification through bushing service.

HD adjustable trailing arm sets address the rear geometry correction requirement that arises when performance alignment targets, modified ride heights or specific track setup requirements place the desired rear camber or toe angle outside what the factory arm geometry can achieve. The adjustable inner pivot delivers continuous correction within the arm's available adjustment range, enabling the rear geometry to be set precisely at the alignment rack and maintained correctly under the suspension loads of performance and demanding use.

Compatible Vehicles

Trailing arm kits are compatible with a wide range of vehicles, including:

• Applicable RWD performance vehicles with multi-link or semi-trailing arm rear suspension requiring rear trailing arm set renewal where the arm structure or inner bore condition requires full replacement rather than bushing service.
• Applicable Applicable performance and 4WD platforms requiring HD adjustable rear lower trailing arm sets where rear geometry correction beyond the factory arm's range is required, whether from a modified ride height, a performance alignment target or a track use geometry requirement.

Installation and Support

Trailing arm kits install at the rear lower trailing arm chassis inner pivot and rear knuckle or hub carrier positions on applicable platforms. The rear trailing arm set installs in approximately one hour. The HD adjustable rear lower trailing arm set installs in approximately two hours, with the inner pivot set to the correct correction position during installation. Following installation of either product the vehicle must be presented for a wheel alignment to confirm and set rear camber and toe within specification.

For additional technical assistance, a dedicated support team is available to confirm correct product selection, platform applicability and geometry correction specification for the specific platform and ride height.

Repair and Upgrade

Trailing arm kits are manufactured from quality materials engineered to meet or exceed the structural specification of the factory arms they replace. The rear trailing arm set provides OEM-specification arm geometry and structural integrity for direct factory-specification rear wheel location on applicable RWD performance platforms. The HD adjustable rear lower trailing arm set is built to a heavier construction than factory equivalent arms, providing increased structural rigidity and load capacity for performance, modified and 4WD applications where the factory arm design is not adequate for the required geometry correction or structural demand. The adjustable inner pivot maintains the set geometry under sustained suspension loads throughout the service life of the installation.

Who Trailing Arm Kits Are For

Trailing arm kits are a practical solution for:

• Professional workshops completing rear suspension structural repairs on applicable RWD performance platforms where the rear trailing arm requires full structural replacement at one or both rear positions due to impact damage, corrosion or inner bore condition.
• Performance vehicle owners and track users on applicable performance platforms requiring HD adjustable rear lower trailing arm sets to achieve rear geometry targets beyond the factory arm's correction range, enabling the rear suspension to be correctly aligned to the desired performance specification.
• Modified and lifted applicable 4WD owners requiring HD adjustable rear lower trailing arm sets to restore correct rear geometry at a modified ride height where the factory arm geometry can no longer achieve the required alignment specification.

The right trailing arm kit restores correct arm geometry and structural integrity at every renewed rear trailing arm position, enables the rear suspension to be correctly aligned to factory or performance specification, and delivers the rear wheel location consistency and handling precision that a correctly engineered and correctly fitted trailing arm provides.
