Product details
The PMO PM-O510-0 is an investment-cast aluminum front suspension crossmember that replaces the factory steel crossmember (OE 901-341-013-03 and 911-341-013-10) on the 911 from 1968–1989, the 912 from 1968–1969 and 1976, and the 914 from 1970–1976. PMO took an OE sample, 3D scanned and modeled it, and reproduced it in aluminum as an exact replica that keeps all of the factory dimensions and specifications. The control arm mounts are CNC finished, which PMO says delivers precise front-end alignment for improved handling. PMO describes it as a bolt-in part that increases structural rigidity while decreasing sprung weight.
The crossmember carries the front control arm mounts, so the machined mounting faces are what set the geometry once it is in. Cars coming off the factory steel crossmember need two brackets, Porsche 911-341-031-01, ordered with it; EMPI also lists JP Group JP-9923-0 as an alternative. Buy both brackets at the same time so the car isn't sitting on stands waiting for parts. Because the control arms come off for the swap, plan any control arm bushing or other front suspension work for the same job. It suits track builds chasing weight and restorations where the factory crossmember is damaged.

Fitment & Compatibility
PMO lists the 911 from 1968–1989, the 912 from 1968–1969 including the 1976 912E, and the 914 from 1970–1976. Confirm whether your car still has the steel crossmember, because that is when the two conversion brackets are required.
Installation & Tuning Notes
Fit the two conversion brackets when replacing a steel crossmember. Unbolting the control arms disturbs front geometry, so set ride height and have a full front alignment done once everything is torqued.
Common Questions
Do I need anything else to replace my steel crossmember with this one?
Yes. PMO requires two 911-341-031-01 brackets when converting from the OE steel crossmember. EMPI also lists JP-9923-0 as an alternative bracket.
Does this fit a 1976 912E?
Yes. PMO lists the 1976 car along with the 912 from 1968–1969.
Will it fit a four-cylinder 914?
PMO lists the 914 from 1970–1976 without splitting four-cylinder and six-cylinder cars.
PMB Performance has spent 20+ years on classic Porsche suspension and can help confirm the brackets for your chassis.
