PROBLEM SOLVING HOT ROD CHASSIS PARTS FOR OVER 40 YEARS.
GM has used a triangulated rear 4 link in many of their cars for decades. The design eliminates the Panhard bar. To accommodate many frame widths, the formed upper frame brackets may need to be trimmed. Bars are 1″ heavy-wall seamless tubing, tapped one end 3/4-16 (or 5/8-18 for the standard bushing kit) and notched for the urethane bushing tube on the other end. Upper bars are about 18″ c-c and lower bars are about 25″ c-c. Coil-overs can be mounted in one of three holes on the axle brackets. The bracketry for each kit is matched to the OD of the bushing for a clean appearance.
Axle brackets and upper axle tabs are 3/16″ pickled & oiled mild steel. Upper frame brackets are CNC formed 10 gauge pickled & oiled mild steel. The part of the bracket which welds to the frame for the lower frame brackets is 3/16″ thick, and the formed bar brackets are 10 gauge P&O mild steel.
Please see related products for an adjustable ride height setup tool
that can be used in place of your coilovers while you build the car. You
can keep your coilovers in perfect condition and make sure you have
room for things like exhaust and the driveshaft through suspension
Available with axle brackets for 3-1/4" tubes too - see Add-Ons. Only with large bushing kit.

Every customer is different. You’re different from the next customer. That’s why they’re called 'custom'ers. There is no formula, no equation that will work with all of you. It takes a different approach to everyone to determine how best to serve anyone. Some people need videos, some people need descriptions. Some people need us to weld it together. Our approach has been, and will always be, to serve each of you where you are and to treat you the same way we would like to be treated. We officially opened the doors to Welder Series in 2005. That doesn’t sound like very long, because the product line has been percolating for over 40. Paul Horton began developing and building many of the parts we still manufacture when I wasn’t yet a twinkle in Dorothy’s eye. Thanks very much for your business and support over the years.

Note DW and Paul Horton at Welder Series absolutely rock and were quick, prompt, by far the best communication I’ve had with an online vendor in a LONG LONG TIME… (Sorry but their response time was bar none awesome). Very rarely do you find the level of dedication to a customer, communication, and a rewarding experience for both the buyer and supplier. I bought a pedal assembly a bit ago, and that experience automatically ensured that I will source Welder Series before I search for another vendor. Paul and DW have it together and will make a solution to your problem… and probably at the best price around to boot.
