solid aluminum, fit snug, excellent quality and good price (for those of us that don't own a lathe). the only downfall to these is the increased chassis noise.
These are great products much like everything from Speed-source.net Used to have alignment issues with the front and rear motor mounts - especially if they were filled or solid inserts used. But with the use of SS alloy cross member bushings alignment of the motor mounts and cross member is effortless. To help isolate the noise alittle I placed a thin delrin washer on both ends of the bushing.
any one got measurnements for those of us that must pay more for shipping that for actual product.... itself.. damn... why they didnt make teleporters yet... damn why not...
