Lemfoerder 31 12 2 284 532 Front Right Upper Control Arm Tension Strut with Bushing

The Lemfoerder 31 12 2 284 532 is a front right upper control arm — also referred to as a tension strut or thrust arm — engineered as an OEM-quality replacement for BMW M-series performance vehicles. This complete assembly includes the integrated rubber bushing and ball joint, delivering a direct, no-modification installation that restores factory ride comfort and handling precision.

Key Features:

• OEM Specification: Manufactured by Lemförder, a ZF Friedrichshafen AG brand and trusted OEM supplier to BMW and over 50 other vehicle manufacturers worldwide
• Complete Assembly: Supplied as a complete tension strut inclusive of the inner rubber bushing — no separate bushing purchase required
• Front Right (Passenger Side) Position: Designed specifically for the front right forward upper control arm location
• Precision Wheel Guidance: Restores proper wheel alignment geometry, steering precision, and suspension response degraded by worn or collapsed bushings
• OEM Cross-Reference: Matches BMW OE part number 31 12 2 284 532; also cross-references Lemförder 35701 01 and 38257 01
• Direct Replacement: Mounts exactly like the original component for a straightforward, professional installation

Over time, the inner rubber bushing can degrade from age, mileage, or rough road conditions, leading to steering vibration, imprecise handling, and looseness in the front suspension. Replacing this tension strut with a Lemförder unit ensures the suspension geometry and road feel are returned to factory specification. Lemförder components are manufactured to meet or exceed BMW's original design standards for fitment, durability, and performance.
