Buying Guide: Key Considerations for Heavy-Duty Ramp Springs
What shaft diameter and fitment matter?
Most heavy-duty ramp springs are designed for 1-1/2″ or 1.5″ shafts. Verify the shaft diameter and inner/outer diameters (I.D./O.D.) to ensure proper seating and function. Mismatched sizes can cause binding or premature wear.
Deflection and torque expectations
90° deflection and 2000 lb torque are common benchmarks for lifting and lowering heavy ramps. Higher torque offers easier lifting but may increase initial stiffness. Balance your ramp weight with the torque rating for smooth operation.
Material and forging processes
Forged steel and high-temperature forging improve strength and reduce deformation under load. Consider tubes or springs manufactured with heat treatments if you expect frequent, heavy use or exposure to elements.
Left/right pairing vs. multi-pack kits
Dual-spring kits (left and right) provide balanced action across gates. Multi-pack kits are convenient for multi-ramp configurations or future replacements. Assess whether you need a single pair, a dual kit, or a three-pair arrangement.
Durability and environmental exposure
Coatings and alloy composition impact corrosion resistance. For outdoor trailers or frequent exposure to moisture, select springs with protective coatings to extend lifespan.
FAQ
- What does 2000 lb torque mean for ramp springs? It indicates the output force the spring can apply to assist lifting the ramp, improving ease of use for heavy gates.
- Do I need springs on both sides of the ramp? Yes, pairing left and right springs provides balanced operation and reduces uneven load during lifting and lowering.
- Can I replace only one spring if the other is fine? Replacing a single spring is possible but not recommended; mismatched tension can cause uneven action. Replace in pairs when possible.
- How do I confirm the right spring kit for my trailer? Check shaft diameter (usually 1.5″), deflection needs (90°), and torque rating (around 2000 lb). Match RS16933LH/RH designations if specified by your ramp model.
- Are forged springs more durable than others? Generally, forged springs with high-temperature processes resist deformation better under heavy use and harsh conditions.
- What maintenance is needed? Periodic inspection for wear, lubrication of moving joints, and replacement when signs of fatigue appear helps prevent ramp failures.
