The GM-52287 Balancer Holder Kit is used to remove and install the balancer bolt due to the high torque and angle requirements for balancer bolts. GM‑52287 is held using the GM-956-1 Extension Handle, which can be held against the vehicle frame or cradle using the GM-52287-5 Reaction Bar.
The GM-52287 kit includes adapters, engagement pins, and extensions to fit most GM gasoline and Diesel engine balancers, and can also be used to hold hubs for removing and installing axle nuts.
