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
