The new design is 4.3 oz lighter per assembly! Tube coupler/interlocks for 1.625″ (1 5/8″) diameter tube with .083″ thickness. This size tubing is mandated in most NHRA Chromoly cage work and is a popular size of tubing for drag racing oriented shops.
These 4130 Chromoly interlocks are a safe and effective way to make elements of your tube work removable or break down for shipping purposes. These are what we use in all of our bolt-in Chromoly roll bars and parachute bars. The Rampage Chromoly interlock is unique in that you can use two size of tubes with it. Put your 1.625″ over the interlock or insert a 1.25″ OD tube into the interlock. Versatile, safe and effective.
1.625″ x. 083″ (1 5/8 x .083″) x 3.5″ long
