Adjustable 13" 4 Link Chassis Brackets (Economy)

We have came up with an economical solution for 1/8" adjustment tuning on the traditional chassis 4 link bracket. The bracket assembly is made of 4130N making it a great choice for longevity and durability. Heim bracket adjustment range is suitable for both small and big tire applications.

The 1/4 bolt serves as the adjustment indicator for a given heim hole choice, adjusting through the sweep in 1/8" increments up to 5/8" before needing to adjust to the next heim hole.  Because the upper adjustments are on an angle, the upper 4 link bar stays at the same approximate nominal length through the adjustment sweep making the adjustment variable more consistent. 

Specs:

• 4130N material
• 1/4" main brackets layered x 3 for overall width of 3/4"
• 1/4" heim brackets
• 1/8" doublers
  
• 12pt grade 9 hardware
• 22" Radius on upper hole arc
• 1 5/8" Tube notches
• 13" Spread (top of lower notch to bottom of top notch)
• 4 deg angle between upper and lower notch center
• 1/2" Holes on 5/8" spacing
• 1/8" adjustment capability
• No lightening pocket in center of bracket making it a good location to weld support tube gussets

***Requires TIG welding. The perimeter of the main bracket layers has an 1/8" step to allow for a good welding surface.  Additionally, the lightening pockets serve as a perimeter for additional welding for maximum bonding and strength***

***Recommend welding no more than 2” at a time alternating ends and sides to minimize heat and distortion.  Clamp to a flat surface is best ***
