It's a male aluminum rod end in the ALJM / ALRSM / ALJF series, with a 0.3750 in bore (B) and 1/2-20 UNF external thread. Right-hand thread (ALJMR8-6(T)) and left-hand thread (ALJML8-6(T)) are available as a matched pair for turnbuckle-style adjustment or as individual ends for fixed-length linkages. Typical applications include motorsport suspension, sway-bar links, custom chassis build, and industrial control joints in the 1/2-inch thread class.
Static load is rated at 7,698 lbs with up to 12° of misalignment, covering the majority of mid-weight motorsport and off-road suspension requirements in the 1/2-inch thread class.
The body is 7075-T6 aircraft aluminum, color-anodized red or black standard (other colors available), paired with a hard-chrome-plated 52100 bearing steel ball and an alloy steel race. A PTFE-lined race option is available by adding the -T suffix (ALJMR8-6T / ALJML8-6T), eliminating the need for re-lubrication in sealed or hard-to-access linkage locations.
ALJMR8-6(T) is the right-hand thread version and ALJML8-6(T) is the left-hand thread version of the same male rod end — available as a matched pair for turnbuckle-style adjustment or as individual ends for fixed-length linkages.
Overall assembly length (AM) is 2.438 in end to end, thread engagement (CM) is 1.500 in, width across the eye (W) is 0.625 in, and body thickness (T) is 0.500 in — approximate weight is 0.140 lbs.
The 0.937 in ball runs in a 1.312 in body, matching the 0.3750 in bore (B) and 1/2-20 thread.
