Which one is best for my application Selecting a fourlink or ladder bar suspension
Benefits of a FOURLINK:
The improved suspension adjustability is the greatest benefit and can shorten quarter mile times, or more specifically, 60 ft. times through fine tuning of the instant center to yield an optimal percentage of rise for varying track or traction conditions.
They are well suited for short wheelbase cars that have minimal clearance from the rear axle centerline to the drivers seat. They are also well suited for Street Rod and Pro Street applications where uneven road surfaces are encountered which can be compensated for by running the bars in a parallel fashion.
Benefits of LADDER BARS:
A Ladder Bar suspension is a substantial improvement over a stock suspension that may utilize a pair of leaf springs or trailing arms and helps eliminate spring wrap-up on leaf spring equipped cars. It is quite easy to install and maintain, and typically requires fewer floorboard modifications. Adjusting a pair of ladder bars is quite easy due to the fact that there are only adjustment holes at the front of the bar. The remaining adjustment is in the lower portion of the bars and is for returning the pinion angle to its correct position at 1 to 2 degrees nose down in relation to the driveshaft.
