Transform rear-end stability on your BMW E46 xi and xd all wheel drive

Take control of rear axle movement on your E46 3 Series four wheel drive with this uprated polyurethane RTAB pair. Part number PFR5-3608 delivers a direct replacement solution that tightens up the back end, improves braking confidence and keeps alignment true under load. If your AWD E46 feels vague, tramlines or chews through tyres, this kit is the go-to upgrade.

What you will feel

• Sharper turn-in and more predictable handling on B-roads and motorways
• Reduced rear steer and squirm under hard braking and acceleration
• Consistent geometry control that helps protect tyres from uneven wear
• Less unwanted deflection compared to tired factory rubber
• Excellent day-to-day comfort with a performance edge
• Built to last and backed by a lifetime warranty

Why polyurethane makes the difference

Correctly engineered polyurethane resists deformation, heat, oil and road contaminants far better than ageing OE rubber. That means the trailing arm stays located, alignment stays where it should be and the car tracks straight, corner after corner. More grip, more confidence, less hassle.

Real-world results

We run these bushes on our own E46 builds and customer cars. Feedback is consistently positive: tighter rear axle location, cleaner turn-in and a calmer, more settled drive in wet or dry conditions.
