Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you.

Fall-Line Motorsports Rear Upper Control Arm Spherical Bearing and Monoball Kit for BMW M2, M3, M4 is the proven rear suspension upgrade for drivers who want sharper handling, rock-solid alignment and repeatable performance on road and track. Replace the soft factory rubber rear upper control arm bushings with precision spherical bearings to stabilise camber and toe under load, improve rear-end stability and unlock faster, more connected steering response. Ideal for BMW G80 G81 G82 G83 G87 and F80 F82 F83 F87 platforms.

This rear upper control arm monoball conversion is engineered and Made in USA to deliver motorsport-grade precision on the BMW M2, BMW M3 and BMW M4. If you are searching for BMW G80 rear upper control arm bearings, BMW G82 M4 spherical bearings, BMW G87 M2 rear monoball kit or F80 F82 F83 F87 rear control arm bearing upgrades, this Fall-Line kit is a standout solution that enthusiasts trust.

Key performance gains

  • Eliminates bushing deflection to keep rear camber and toe stable during hard cornering and braking
  • Gives a planted, connected rear axle with faster response and precise driver feedback
  • Reduces geometry change so your alignment stays true under heavy load for better tyre control and grip
  • Perfect for track days, fast road driving and serious BMW M builds focused on consistency and confidence

Built to perform and last

  • DMG Mori 5-axis CNC machined for exact tolerances and repeatability
  • Full stainless bearing assembly including hats, bearing, housing and spiral locks
  • Designed to rigidly mount the rear upper control arms to the subframe for maximum precision
  • Price is per set of 4 bearings, 2 per side, replacing the inner bushings of the rear upper control arms
  • Made in USA

As with any bushing delete, expect an increase in noise, vibration and harshness. The trade-off is a substantial jump in handling consistency, traction on corner exit and alignment stability that inspires confidence lap after lap and mile after mile.
