Progressive Linkage Collars - 3/16

Precision CNC-machined from 316 stainless steel, these linkage collars are designed as adjustable stops for traditional progressive linkage setups using Stromberg 97 or Holley 94 carburetors. Sized for 3/16" linkage rods, each collar allows fine adjustment of throttle progression and locks securely in place using two stainless steel set screws. Clean geometry, positive clamping, and corrosion-resistant material make these ideal for long-term use in demanding engine bay environments. A small but critical component for dialing in smooth, repeatable progressive operation. Sold in packs of 2
