Product Details
If your classic 3 Series or Z4 is starting to feel a bit loose in the rear end—maybe it’s wandering under hard braking, or tramlining down uneven highways—you are likely dealing with tired outer control arm bushings. On these legendary BMW chassis, the factory rubber bushings at the wheel carrier undergo massive multi-directional loads. Over time, they turn soft and sloppy, letting your rear toe and camber angles dance around exactly when you need them to hold steady.
The Powerflex Heritage Series is the ultimate "fix-it-once-and-forget-it" upgrade. Engineered specifically for classic restorations and daily drivers, the Heritage Series gives you all the crisp handling advantages of modern polyurethane technology, but rolls out of the mold in a subtle, period-correct dark grey. It keeps your car looking entirely stock from underneath while completely transforming the way it handles.
Why You'll Love the Heritage Series
Precision Without the Harshness: These bushings are formulated to deliver sharp, predictable handling and stable alignment settings without turning your ride into a bone-rattling track monster. It’s the perfect balance for spirited weekend canyon carves and daily commutes alike.
Period-Correct Aesthetic: Want to keep your classic looking classic? Unlike standard bright purple or yellow performance bushings, the Heritage Series blends right into your suspension, looking just like an OEM rubber piece to the untrained eye.
Bulletproof Longevity: Standard rubber cracks, rots, and fails when exposed to road salt, oil, and time. Powerflex’s advanced polyurethane compound is entirely immune to the elements.
Dual-Location Versatility: Depending on your specific BMW model, this versatile bushing can be used in both the Rear Upper and Rear Lower outer control arm positions (where the arms meet the rear wheel carrier/trailing arm assembly).
