Easy 4-Link Kit B - Triangulated Adjustable Uppers
Easy 4-Link Kit B builds the same single-triangulated 4-link as Kit A — angled uppers over straight or slightly angled lowers — but with adjustable upper links, so pinion angle and caster stay tunable long after the brackets are welded. That matters on a fresh build: springs settle, driveline angles change, and threading a link in or out beats cutting one apart. It is the middle option in Artec Industries' Easy 4-Link lineup, with more tuning range than Kit A and less complexity than Kit C's dual triangulation.
Features
- Single-triangulated 4-link with adjustable, angled upper control arms
- Adjustable uppers dial in pinion angle and caster during setup and after settling
- Heat- and cryo-treated chromoly rod ends: 7/8"-14tpi x 3/4" bore uppers, 1.25"-12tpi x 1" bore lowers
- All-1.25" rod end and PRO KRAWLER cartridge joint variants available
- CNC laser-cut and bent frame and axle brackets with separate upper and lower frame-side mounts
- Eight wide 3/4"-9/16" stainless high-misalignment spacers
- Optional DOM tube in 4-ft lengths of 1.5" and 2" OD; brackets-only option offered
As with every kit in the line, this is universal fabrication hardware for coil and coilover solid-axle builds — you set the geometry and weld the brackets, so bring real fab skills or a shop that has them. Compare the fixed-upper Easy 4-Link Kit A if budget leads, or the dual-triangulated Easy 4-Link Kit C to delete the track bar entirely. Shop supporting parts in control arms and coilover kits.

Easy 4-Link Kit B FAQs
Why choose adjustable uppers?
Upper link length controls pinion angle and caster. With adjustable uppers you can fine-tune both during setup and again after the springs settle or you change lift height — thread the link in or out instead of cutting and re-welding a fixed arm.
How does Kit B compare to Kit A and Kit C?
All three share the chromoly joint package. Kit A uses fixed triangulated uppers and is the simplest; Kit B adds adjustability to the uppers; Kit C triangulates both uppers and lowers so the axle is located without a track bar. Kit B is the middle ground for most coil and coilover builds.
What is included, and what do I still need?
The kit supplies chromoly rod ends, tube adapters, jam nuts, eight wide stainless misalignment spacers, and CNC-cut frame and axle brackets; DOM tube in 4-ft 1.5" and 2" OD lengths comes with the tube options. You supply the vehicle-specific geometry, cutting, and welding — this is a fabrication kit, not a bolt-on.
