Our new link tubes are from 1-1/4" x .219 DOM. The tubes are tapped with 7/8"-14 RH/LH threads for easy on the fly adjustment. They also have a slight tapered at the ends, and come with a Superdurable matte texture powder coat. All this mean is that your link are protected and won't turn chalky due to UV light.
When quality, reliability, and durability matter you go with the best. Our joints were designed and built by Summit Machine, and their Flex Joints have proven to be the best available over time! The billet housing is zinc plated after being beautifully machined to add rust and corrosion protection. Machined with precision and exacting standards with threads complying with ANSI standards. Races are machined from an engineered plastic complete with grease grooves in the race concavity. These grooves keep grease surrounding the ball and ensure they are nice and quiet. No more squeaky heims! The Center pivot ball is machined from mild steel with a smooth nickel plating for even wear with races and added rust prevention. The flat washer and machined threaded retaining ring are yellow zinc plated for corrosion resistance.
