Allstar Steel Bird Cages With Roller Bearings

4-Link Suspension Bird Cages Provide Maintenance Free, Smooth Bearings

These steel bird cages from Allstar Performance are compatible with many varieties of racing vehicles using a four link rear suspension setup. The steel birds cages double shear radius rod mounting brackets for increased strength and reduced flexing. They also include maintenance free, sealed roller bearings. These sealed roller bearings provide smooth action throughout the entire suspension range. There are also multiple shock mounting locations, with swivel and solid mounts, to allow for complete customization of shock height and suspension performance. All steel bird cage kits also include high misalignment bushings. These allow additional radius rod travel, which helps to prevent binding under severe angles. These units should be used with machined axle tubes. The bird cages are offered with two different sized roller bearings.
