This short arm 4-link is designed for trucks that see hardcore use—perfect for drag racing, sled pulling, or heavy boosted launches.

Precision-engineered geometry works on lowered trucks (down to -2.5") up to lifted heights of 3.5". For taller lifts, consider our Long Arm 4-Link alternative.

Frame-side mounts are crafted from 1/4″ laser-cut steel with internal gussets, bolting into the stock radius arm basket. Optional hole locations support extreme applications. Lower arms stay tucked close to the frame for maximum ground clearance.

All bars are 2″ OD DOM tubing with .250″ wall thickness. End links are offset for improved turning clearance. Frame-side joints feature USA-made FK Heim joints rated over 76,000 lbs static load. These provide zero flex—ideal for racing—but road impacts like potholes will be more noticeable.

This bolt-on kit comes powder-coated and includes:

• 2 Frame-side 4-link mounts
• 2 Upper 4-link bars
• 2 Lower 4-link bars
• 4 FK Heim joints with misalignment spacers
• Hardware kit

Note: This kit is not compatible with trucks equipped with the Auto Sensing Scale System (those with sensor arms on the front radius arms and rear leaf packs). We’re working on a package for that setup.

Why Choose This Kit?

• Eliminates front wheel hop under hard launches or sled pulls
• Superior strength with 2″ .250" wall DOM tubing and FK Heim joints
• Optimized geometry protects drag racing and 4-high abuse applications
• No flex design for maximum power transfer and response
• High-clearance design keeps lower arm close to frame
