If you're "G Body" General Motors Race or street car uses "stock" trailing arms, take a look at this part! Many racers and car crafters want the advantages of a monoball type insert, but are prohibited by rules or don't like the noise, harshness or vibration of the monoball. Seals-it has solved the problem with a new Trailing Arm Bushing Insert for "G Body" cars! Using an Elastomer bearing, these parts replaces hard, deteriorated or worn out stock rubber bushings and provide movement like a monoball. This construction will satisfy many rule requirements requiring "rubber only".
