Product Details
These CNC-cut 6061 aluminum suspension brackets are precision-engineered replacements for OEM Arctic Cat parts 1607-332 / 1607-333, which supersede the earlier 1607-078R / 1607-078L brackets.
Constructed from 6061-T6 aircraft-grade aluminum, these brackets are stronger and more rigid than OEM steel stampings, with added mounting reinforcement in critical stress areas. The improved design also stiffens the rear tunnel cap, reducing flex and fatigue around the rear suspension mount points — especially under aggressive riding, deep snow loads, or boosted sled setups.
Each kit includes:
Available finishes:
-
Raw Aluminum
-
Satin Black Powdercoat
-
Gloss White Powdercoat
