• If you have another brand of arms we haven't measured, please let us know. We can work with you to take the correct measurements, or you can send them to us to measure.
• Before pressing any bushings into your arms, you MUST measure the bushing outer diameter and the control arm hole inner diameter. There must be an interference fit of .001-.010" in order for them to assemble. Ideally, you want to be between .002-.006" to be safe. .007-.010" will be very hard to press in. Over that may destroy the arm or bushing, or leave the arm structurally compromised.
• Vehicles with steel and aluminum uprights have different ball join sizes. If purchasing assembled control arms, please make sure to select the correct option.

Construction

We use only the highest quality motorsport-grade PTFE-lined bearings for best performance and lifespan. We use high strength 7075 aluminum for the bolt sleeves, and 6061 for the bearing cups. Bearings are interference-fit into the cups, so they won’t creak or rattle. Both internal and external retaining rings ensure everything will always stay in place.

Please note that lifespan will vary based on the application and driving conditions. Spherical bearings do have moving parts, so they do wear. Our bearing kits are fully rebuildable and do not require the cup to be removed from the arm to do so. Please contact us for rebuild kits.
