Spring Swivler w/ Bolt

The Spring Swivler w/ Bolt from AFCO Racing Products is a precision weight jack assembly designed for front-end suspension tuning in high-performance racing and automotive applications. Built for professionals who demand exact load distribution control, this component allows real-time adjustment of vehicle dynamics during setup and testing. Whether you're running road course competition or street performance builds, the Spring Swivler w/ Bolt provides the mechanical advantage necessary to fine-tune spring preload and chassis geometry with repeatability.

This upper front assembly features a 1-8 inch thread bolt connection and cadmium plating for corrosion resistance under demanding track conditions and weather exposure. The swivel design distributes load evenly across 5-inch OD springs, enabling balanced force application without binding or uneven wear. The bolt-secured mounting ensures positive engagement and prevents drift during load cycles, critical for maintaining consistent suspension geometry lap after lap. At 2.88 lbs, the compact footprint (4.9 x 4.75 x 8.75 inches) integrates seamlessly into OEM and custom chassis without excessive material removal or complex fabrication.

Mechanics, race engineers, and automotive technicians benefit most from this component when performing front suspension work on competitive vehicles or performance street cars. Installation requires basic mechanical knowledge and standard tools; the 1-8 inch threaded connection accommodates most standard racing jack points and lift equipment. Compatibility spans multiple chassis platforms where modular weight jack assemblies are factory or aftermarket standard. For precise suspension tuning and reliable long-term performance, the Spring Swivler w/ Bolt delivers professional-grade results without compromise.
