The BMW X4 F26 control arm rubber bushings and chassis damping bushings are core rubber elastic components in the front suspension system, responsible for vibration damping, positioning, and cushioning. Installed at the connection point between the front control arm and the subframe, these bushings, through the deformation and rebound of the highly elastic rubber body between the metal frame, continuously absorb longitudinal impacts and lateral forces from the road surface during vehicle operation. Simultaneously, they flexibly connect the two rigid metal structural components, effectively isolating the path of vibration transmission to the vehicle body. They are not only key support components for maintaining the geometric accuracy of front wheel alignment (toe angle, camber angle), but also indispensable basic components for suppressing chassis noise and improving driving comfort. Carefully designed for the chassis structure of BMW X2, X4, F25, and F26 series models, their dimensions and mounting holes are completely replicated according to original factory specifications, ensuring that the suspension system is restored to factory condition after replacement. They are suitable as standard spare parts for routine maintenance and major chassis overhauls.

Precise Size Matching: The 46.5mm outer diameter ensures an interference fit with the subframe mounting holes, guaranteeing a stable and secure fit after press-fitting; the 12mm inner diameter precisely matches the control arm bolts, eliminating gaps and wobbling; the 54mm length ensures sufficient rubber travel and stable cushioning.
Integrated Vulcanization Molding: The inner and outer metal skeletons and rubber body are integrally molded through a high-temperature vulcanization process, resulting in high bonding strength and preventing delamination or detachment.
Optimized Rubber Formula: Utilizing high-elasticity, high-damping rubber composite materials, it possesses excellent elastic deformation capabilities in both axial and radial directions, balancing cushioning and rebound speed.
Surface Treatment: The metal skeleton undergoes rust-proofing treatment, adapting to complex operating environments such as humidity, salt spray, and low temperatures, delaying oxidation and corrosion.

Functional Dimensions: As a core support component for front suspension geometry positioning, the LJ-721 control arm bushing, through precise dimensional reproduction and elastic damping ratio, effectively maintains the design accuracy of the front wheel toe angle and camber angle, preventing abnormal tire wear and steering drift caused by bushing aging and deformation. Its multi-directional cushioning properties simultaneously absorb longitudinal impacts and lateral forces from the road surface, significantly reducing chassis vibration transmission and dramatically improving driving dynamics and ride comfort.

Durability: The product uses a fatigue-resistant and tear-resistant high-performance rubber system, capable of withstanding long-term, high-frequency tensile, compressive, and torsional composite loads on the front suspension nodes. The metal frame undergoes anti-corrosion treatment, ensuring no rust occurs during long-term use in humid, salt spray, and extreme temperature environments. The vulcanization process guarantees the bonding strength between the rubber and metal interfaces, preventing delamination and failure, resulting in a significantly longer overall service life than ordinary commercially available replacement parts.

Compatibility: Exclusively compatible with BMW X2, X4, F25, and F26 series models, covering many popular models on this platform, enabling cross-model compatibility with a single product. Installation dimensions are strictly controlled within the original factory tolerance range, allowing direct replacement of original parts without any modification or additional processing, significantly reducing repair labor costs. Suitable for authorized repair shops and independent repair shops to stock in bulk.
