When committing to building a ground-up, early-model custom truck, it is definitely a major undertaking. My youngest son Casey drove a '50 Suburban during his high school days, and after graduation, he downsized to a smaller ride during his college years. I had been storing the stock 'Burban in the family garage. Recently, I decided it was time to transform the daily surf-wagon into a serious custom boulevard cruiser. It was wise to consider a new frame and suspension into the build's equation, and while we were looking for high quality frame and suspension components, we looked no further than Chris Alston's Chassisworks and KP Components in Sacramento, California.
Chris Alston's Chassisworks has been manufacturing early-model truck frames for many years. However, they had never bent framerails for a '48-'54 Chevy or GMC Suburban. The CAD-designed 4x2x.120-inch g-Machine framerails with front tapered horns were CNC mandrel-bent. The framerails were separated by a 4x2x.120-inch large radius front crossmember and a mid-frame crossmember featuring a 9x5-inch driveshaft loop flanked by two 4-inch ID exhaust ports.
The front Street Machine independent front suspension (IFS) consists of 20-inch polished stainless steel TIG-welded .156-inch-wall tubular upper and lower A-arms. A pair of black sculptured dropped spindles were linked to the 211/2-inch power steering rack with OEM tie-rod ends. The 3/4-inch diameter front antiroll bar with custom endlinks will eliminate some of the front body roll. The polished billet aluminum four-bar canted links suspended the Fab9 rearend housing. A rear ball-end 7/8-inch diameter torsion lever-style antiroll bar will minimize any rear body roll and help the old 'Burban handle like a modern sport truck.
Watch us as we bolt on the Chassisworks suspension components to the g-Machine frame. We moved forward 60 years in one install. This transformation took place at Ironworks Speed & Kustom in Bakersfield, California.
