Being in Hawaii it’s usually tough getting heavy truck parts out here. The guys at CJC Off-road made it easy and pain free! Thuren Radius Arms are as advertised! Will give a full review on Garage Install and first 10,000 miles!
Firch Fab is a small fabricator in Northern California making a name for himself with hand built products. These Firch Fab 2014+ Dodge Ram 2500/3500 radius arm/long arms are a replacement for improved suspension articulation and better tire clearance. Purpose built for off road but still comfortable and practical on the street, these are a great upgrade to get the most out of your truck and work on trucks with 0-3" of lift.
Constructed from 3/16" wall material with multi directional internal bracing for the length of the arm, this setup also boasts a significant increase in strength over stock.
These arms are designed to retain the factory cam adjustment bolts for easy caster adjustment after install. The arm also feature a bent design for better tire clearance than most long arm kits on the market. These are built to order, with a 4-6 week lead time.
