Ultimate Duty Harmonic Balancer Bolt KitBig Block Chevy 1/2 in.-20 Threads Extra-Tall 12-Point Head Accepts a Deep 5/8 in. Socket 2 in. Diameter Machined Flat Washer Chrome Moly Steel Sold as a Kit
The balancer bolt is the only thing holding the balancer, and the front of the crank, together. A rounded-off head or a bolt that stretches turns into a walked balancer and a wiped snout. This one is machined and thread rolled after heat treating, and the extra-tall 12-point head gives a deep socket real purchase for installation and removal.
Moroso 38775 Ultimate Duty Balancer Bolt Kit Features:
- Fits big block Chevy cranks with 1/2 in.-20 threads.
- Chrome moly steel with a large built-in washer flange.
- Machined and thread rolled after heat treating for strength and accuracy.
- Extra-tall 12-point head accepts a deep 5/8 in. socket without stripping.
- 2 in. diameter washer machined flat to spread the load.
- Black oxide finish.
- Balancer Bolt: The thicker 3/4" hex head on this 7/16"-20 x 2-1/4" Balancer Bolt provides a larger contact surface for more positive socket engagement. Especially important when crankshaft is being rotated by hand with the use of a socket and power bar or ratchet handle. Manufactured of Grade 8 steel with gold iridite finish.
Ultimate-Duty Balancer Bolt: Extra-strength chrome moly steel bolt with large, built-in washer flange exerts 190,000 psi of clamping force to secure balancer firmly in place under severe conditions. Unlike other brands, the bolt is machined and thread rolled after heat treating for superior strength, accuracy and longevity. Extra-tall 12-point head accepts deep 5/8" socket to provide positive grip for removal/installation without stripping. Large, 2" diameter washer is 1/4"-thick and machined perfectly flat to spread the fastening load over a larger surface area. Black oxide finish.
