Jack Bolt Collar 1in-8

The Jack Bolt Collar 1in-8 by Allstar Performance is a precision fastening component designed for chassis builders, fabricators, and automotive enthusiasts who require reliability in critical lift and suspension work. This collar features a 1-inch diameter and is specifically designed for jack bolt applications where controlled clamping and repeatable engagement are essential.

With 8 threads per inch (TPI), this collar accommodates a coarse-pitch thread pattern that resists stripping under heavy loads, making it ideal for automotive fabrication and service environments. Allstar Performance's design ensures even load distribution across the bolt interface, preventing stress concentrations that can lead to fastener failure during dynamic suspension cycles.

This component is particularly beneficial for mechanics and fabricators engaged in frame-off restorations, cage welding projects, or custom lift systems, ensuring that jack bolts seat consistently without galling or thread damage. Its lightweight construction makes it practical for tight engine compartments and underbody applications.
