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.
