STABILIZERLEG ***UPDATED***

Originally, I devised a spring substitute featuring a confined rubber compression cone, replacing the original suspension part. However, the 5000lb maximum compression force in small size led to issues when the size was increased; the main suspension arm redesign for clearance resulted in hinge point mounting failure. Consequently, I opted for a different approach: addressing the root problem. Upon closer examination, the "Haulz-All" suffered from an overlooked flaw - at half load, the spring rate was too high, limiting suspension travel and rendering the suspended rear wheel feature ineffective. My innovative design employs a lever train to reduce force on the spring while distributing point-load forces across components. The load setting adjuster alters compression angles for optimal force application. Despite appearing complex, the design requires minimal manufacturing - only two welds and one bend, excluding the lower arm replacement. Costs should be low. As a backup, I'll also post a simpler, cheaper alternative. Recently, I fine-tuned the geometry and simplified the design, now offering just two load settings (0.89x and 0.445x spring rates) at 45 degrees, along with a park setting. Enjoy!
