This Basysion kit includes a left and right torsion spring matched to the RS16933LH\/RS16933RH specifications and built for 1.5\" shafts. Crafted through high-temperature forging and precision winding, the springs are formulated to resist deformation and maintain performance across heavy-use cycles.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this spring set restore ramp performance?\u003c\/h3\u003e\n\u003cp\u003eThe pair restores balanced torsional force so ramps lift and lower smoothly instead of sagging or snapping. Each spring supplies up to 2000 lb of torque with a 90° deflection range to match common trailer ramp geometries. Installation returns the ramp’s original counterbalance, reducing operator effort and wear on other hardware.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMatched left\/right pair for even torque distribution\u003c\/li\u003e\n  \u003cli\u003e2000 lb torque rating with 90° deflection for consistent assist\u003c\/li\u003e\n  \u003cli\u003eDesigned for 1.5\" diameter shaft fit — no shims required\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and construction ensure long life?\u003c\/h3\u003e\n\u003cp\u003eBasysion springs are formed using multi-stage high-temperature forging that strengthens the steel and refines coil geometry.
