Wehrs Machine Suspension Bearing Bracket

Few components on a dirt or asphalt race car work as hard as the bracket that holds the rear suspension bearing. It carries four-bar loads, locates the axle, and has to keep moving smoothly through every bump and corner. Wehrs Machine & Racing Products has built its reputation on this kind of hardware, and its suspension bearing brackets, commonly called bird cages, reflect the company's focus on strength, adjustability, and easy servicing.

Modular Double Shear Design

The centerpiece of Wehrs Machine's offering is its double shear bearing suspension cage. The company describes these cages as the strongest on the market, and the design backs that up by supporting the bearing on both sides rather than relying on a single-shear arrangement. The cages are also fully modular, so after a hard hit the damaged piece can be replaced instead of cutting apart a welded assembly. For teams that race several nights a week, that repairability matters as much as raw strength.

Quick Adjust Technology

Changing four-bar geometry at the track is normally a chore. Wehrs builds its cages with Quick Adjust Technology: loosen the bolt, pop out the puck spacer, move the bar, and tighten. The spacer package also has high misalignment built in for maximum suspension travel, along with a built-in level for quick reference when checking cage index. These small details reduce time in the pits and help crews return to the same settings reliably.

Brake Combo Cages

The left rear brake combo cage is a standout among Wehrs Machine's suspension bearing brackets. It lets a team run the brake on the cage or as a brake floater within the same assembly. Two independent housings bolt together in the middle to lock the brake to the cage, or they can be unbolted so the floater rod can be hooked up and the pieces run separately. Versions are available with zero index plates, and the assembly is supplied complete except for the shock mounts. This flexibility lets a team change brake setups without buying a different cage.

Precision Machining and Replacement Parts

Wehrs Machine was founded in 1997 by Chad Wehrs in Bangor, Wisconsin, and its parts are made in the USA. The company's machining roots show in the supporting components: replacement roller bearings are offered for its WM200 cages, for use in both steel and aluminum housings, along with dedicated bearing tools. Because the cage, bearing, and hardware come from the same maker, wear items can be refreshed to the original fit.

What to Consider When Choosing

• Brake arrangement: Decide whether you need a standard cage or a brake combo cage that can switch between on-cage and floater setups.
• Index and geometry: Confirm the index plate and drop dimensions suit your four-bar layout.
• Material and housing: Match the bearing and cage to a steel or aluminum housing as specified.
• Shock mounts: Some cage assemblies are sold without shock mounts, so plan for those separately.
