Powerflex PFR5-427 11.4mm Rear Coil Spring Spacer for BMW 3 Series F30 F31 F34 F3x (Saloon/Touring/GT) - Polyurethane Spring Seat Shim/Isolator Pad - RHD Lean Fix, Ride Height Lift & Levelling - OE 33536769473

Powerflex PFR5-427 Polyurethane Rear Spring Spacer - 11.4 mm - BMW 3 Series F30 F31 F34

Level the rear of your BMW and sort that common right-hand-drive lean with this tough polyurethane spring seat shim. Powerflex PFR5-427 adds 11.4 mm at the rear coil spring interface to correct driver’s side droop on RHD cars or provide a subtle, even lift when used as a pair. Simple, affordable and effective stance correction for Saloon, Touring and Gran Turismo models in the F3x range.

We have installed these in-house at MJ Modifications and the results speak for themselves. Customers love the improved symmetry, tidy arch gaps and consistent ride height. No fuss, no creaks, just a smart levelling solution that lasts.

Why this spring shim is a brilliant upgrade

• Corrects the typical RHD sag on the driver’s side - fit one to the low side for a level look
• Use two shims to raise both sides for a balanced, subtle rear lift
• Durable polyurethane pad resists oil, salt and road grime better than ageing rubber
• Helps maintain consistent geometry for confident road manners and even tyre wear
• Quiet, OE-like isolation with the strength of a polybush construction
• Backed by the Powerflex Lifetime Warranty

What it does in the real world

On right-hand-drive F3x cars, crossweight and component ageing can leave the driver’s side sitting lower. This spacer sits at the spring seat to add height precisely where it is needed, restoring a level stance and a tidy, factory-style look. Paired shims deliver a neat, even rear lift without resorting to full suspension changes.

Who is it ideal for

Owners who want a quick, reversible stance fix or a mild rear height increase using a robust spring pad rather than a full spring change. Perfect if you are chasing a smart visual finish, consistent handling feel and reduced arch gap disparity.
