King Pin Leaf Spring Set, H.D

OVERVIEW

When you''re building a rugged off-road rail or restoring a classic King Pin Beetle, the suspension is where the rubber meets the dirt. Standard leaf springs often fatigue over decades of use, leading to a sagging front end and compromised steering geometry that can make your vehicle feel floaty or unresponsive. This Latest Rage King Pin Leaf Spring Set is engineered specifically for enthusiasts who demand more than "just enough" from their front end. By utilizing high-quality Chromoly steel, these leaves offer superior memory and resilience compared to stock mild steel variants. Whether you''re tackling washboard roads in the desert or carving corners on the street, this heavy-duty set provides the necessary tension to keep your front end responsive and your ride height consistent, even under aggressive driving conditions.

This is not just a replacement; it''s a significant performance upgrade for your front torsion housing. This complete kit includes two full packs of leaf springs, measuring 37 inches in length, which is the standard dimension for stock-width King Pin front beams. The heavy-duty designation means these springs are designed to withstand the increased leverage and impacts associated with off-road use, oversized tires, or heavier-than-stock builds. By replacing your worn-out, mismatched, or snapped original leaves with this matched set, you ensure that both the upper and lower torsion tubes are working in perfect harmony. This balance is critical for preventing "beam twist" and ensuring that your king pins and trailing arms operate through their full range of motion without binding or unpredictable spring rates.

PRO TIPS

1. Proper Lubrication is Non-Negotiable

When installing these new leaf packs, do not be stingy with the grease. Use a high-quality, extreme-pressure moly grease. You should coat each leaf pack thoroughly before sliding them into the torsion tubes. This reduces internal friction between the individual leaves and prevents the "creaking" sound often associated with dry front ends. Furthermore, once the beam is assembled, ensure you pump grease into the Zerk fittings until you see a small amount of fresh grease purging from the seals. This creates a hydraulic barrier against moisture and dirt, significantly extending the life of your new Chromoly springs.

2. Align the Center Set Screw Dimple

One of the most common mistakes during installation is failing to properly seat the center set screw (the square-headed bolt in the middle of the beam). These leaf packs feature a specific center point where the set screw must seat to lock the springs in place. Before you tighten the lock nut, ensure the screw has fully engaged the "dimple" in the leaf stack. If the stack is slightly off-center, the screw will only put pressure on the edge of the leaves, eventually leading to the stack shifting, which can cause uneven ride height or even a dangerous loss of suspension travel on one side.

3. Inspect Your Trailing Arm Bushings and Bakelite/Metal Sleeves

Since you have the leaf springs out, this is the absolute best time to inspect the internal bushings and bearings of your torsion tubes. If your trailing arms have excessive "play" or wiggle when the springs are removed, new springs won''t fix your handling issues. Check for scoring on the trailing arm surfaces and ensure the inner bushings are not wallowed out. Installing high-performance H.D. Chromoly springs into a beam with worn-out bushings is a recipe for premature wear. If there is any doubt, replace the bushings and seals at the same time to ensure your new Latest Rage springs can perform at their maximum potential.
