Description
Description
This front 4 link long arm conversion replaces the factory short control arm setup on 03–13 Ram 2500/3500 4x4 trucks and 06–08 Ram 1500 Mega Cab 4x4 trucks. It gives the front axle better control, better geometry, and more adjustment for lifted or air suspension builds.
Choose your lift range, bracket type, and powder finish above. The linked cradle option gives you the strongest connected bracket setup with special overlay/inlay plates for a cleaner finished look.

Installation
Installation: This is a bolt-on long arm conversion, but drilling is required for each frame bracket. The factory frame-side link brackets must also be removed.
- Remove the factory short control arms.
- Remove the original frame-side link brackets.
- Prep and clean the frame.
- Install the selected standard brackets or linked cradle brackets.
- Install the upper and lower long links.
- Install the caster eliminator plates.
- Set axle location, caster, and wheelbase using the adjustable rod ends.
- Final torque all hardware and check clearance through the suspension cycle.
Shop Notes
The Stock – 4" option is the low-height setup used for stock, lowered, lower lift, and FFSonAir applications. The 5 – 12" option is cleaner for taller static lift trucks because it does not need the same low-height clearance bends.
For the strongest and cleanest setup, choose the Linked Cradle option with powder and special inlays.
