Eliminate rear suspension flex and restore precise handling on your BMW E36 / E46 3 Series or E85 / E86 / E89 Z4 with this premium rear control arm outer spherical bushing, precision CNC-machined from 6061 billet aluminium and bearing steel for permanent durability and dramatically improved suspension precision. The rear control arm outer bushing is one of the most overlooked yet critical wear points on the E36 / E46 / Z4 chassis — factory rubber bushings in this location are notorious for tearing, excessive deformation under high cornering loads, and developing the characteristic clunking and popping noises that signal failed rear suspension components. This spherical bushing upgrade replaces the failure-prone factory rubber with rigid bearing steel construction housed in a CNC-machined billet aluminium body, eliminating bushing deformation, preventing rear suspension sway and oscillation, and maintaining consistent camber and toe geometry under all driving loads.

Features:

• Sturdy and durable construction – aircraft-grade 6061 billet aluminium body with bearing steel spherical bushing for permanent strength and consistent geometry control
• CNC machined precision – manufactured to factory specifications for perfect bolt-on fitment without modification
• Anodized surface finish – delivers long-term corrosion resistance and a clean professional aesthetic
• Modular replacement design – the spherical bearing can be independently replaced after wear without requiring full bushing assembly replacement, dramatically reducing long-term maintenance costs
• Direct rubber bushing replacement – eliminates rubber compliance to prevent suspension sway and oscillation under cornering, braking, and acceleration loads
• Maintains stable suspension geometry – consistent camber and toe angles under high loads for predictable handling at the limit

Fitment:

Application verification required – check your application to confirm compatibility before ordering.

• BMW 3 Series E36 (1992 – 1999)
• BMW 3 Series E46 (1999 – 2006)
• BMW Z4 E85 / E86 (2003 – 2008)
• BMW Z4 E89 (2008 – 2016)
• M3 Note: E36 M3 and E46 M3 use factory part number 33-32-6-775-551 on both upper AND lower outer control arm bushings – these applications require two pairs (4 bushings total) for complete replacement
• Confirm vehicle model, chassis code, and factory bushing part number before ordering

Contents:

• Rear Control Arm Outer Spherical Bushings

Benefits:

• Permanently eliminates the rear suspension deformation, sway, and oscillation caused by torn or worn factory rubber bushings – a known weak point on aged E36 / E46 / Z4 chassis
• Resolves the characteristic clunking, popping, and abnormal noises that develop as factory rear control arm bushings deteriorate
• Maintains consistent camber and toe geometry under high cornering, braking, and acceleration loads – critical for predictable handling at the limit and consistent tire wear
• Modular spherical bearing design enables independent bearing replacement after long-term wear – dramatically lower maintenance cost compared to monolithic bushing alternatives that require full unit replacement
• Bearing steel spherical insert delivers significantly higher load capacity than rubber bushings, providing reliable performance under track day loads and aggressive street driving
• 6061 billet aluminium body provides permanent dimensional stability – will not crack, deform, or degrade like rubber alternatives
• Anodized finish maintains the premium aluminium appearance and corrosion resistance for the lifetime of the vehicle

Installation Notes:

• NVH increase warning: This spherical bushing will noticeably increase noise, vibration, and harshness compared to factory rubber bushings. The trade-off is significantly improved handling precision and suspension consistency. Customers seeking only quiet daily driving may prefer rubber-based replacements
• Specialized tools required: Control arm bushing replacement requires a hydraulic press or proper bushing extraction/installation tools – do not attempt installation without correct equipment
• Vehicle wheel alignment is mandatory after installation – control arm bushing replacement directly affects rear toe and camber specifications
• Replace bushings on both left and right sides simultaneously to maintain consistent rear suspension geometry
• M3 Application Reminder: If you own an E36 M3 or E46 M3, you will need two pairs (4 bushings) to replace both upper and lower outer control arm bushings – verify quantity required before ordering
• Apply manufacturer-specified grease to the spherical bearing during installation – do not run dry, as this accelerates wear and noise development
• Inspect surrounding suspension components during installation – worn control arms, sway bar links, or other rear suspension components will compromise the performance benefits of upgraded bushings
• Bed in the new bushings with progressively increased driving loads over the first 100-200 miles before aggressive driving
• Professional installation strongly recommended – control arm service requires suspension geometry knowledge and proper torque specifications
• If unsure about compatibility with your specific BMW variant or chassis code, contact our team with your year, model, and chassis code (E36 / E46 / E85 / E86 / E89) before ordering
