PFF5-401G Polyurethane Front Tension Strut Bush Kit for BMW 3 Series E90 E91 E92 E93 2005 to 2013

Transform the front end of your BMW with this premium polyurethane upgrade for the front lower arm rear position, commonly known as the tension strut, thrust arm, radius arm or lollipop mount. Designed for the E9x platform, this kit delivers sharper steering response, tighter tracking, improved braking stability and more confidence on both street and circuit.

Part number: PFF5-401G

Crafted in a super-stiff 95A black compound and paired with steel outer shells, this kit controls unwanted movement where the arm meets the chassis. The offset, adjustable CNC machined stainless sleeve allows on-car caster adjustment of up to +/- 0.75 degrees, helping you dial in extra in-corner camber gain and front-end bite while maintaining straight-line stability.
