King Pin Beam, 6 Wider, No Shock Towers

OVERVIEW

When you are pushing the limits of an off-road build, stability and suspension travel are the names of the game. This Latest Rage King Pin Beam is engineered specifically for serious sand rails, woods buggies, and custom Baja builds that demand a wider stance and a more aggressive footprint. By stretching the beam a full 6 inches wider than the standard stock configuration, you drastically increase the front-end stability of your vehicle, reducing the risk of tipping during high-speed cornering or while navigating off-camber technical terrain. This extra width also provides the necessary clearance for larger tires and more complex steering setups, ensuring that your front end remains planted and responsive regardless of how much abuse you throw at it on the dunes or the trail.

Constructed from heavy-duty 1010 steel, this beam is designed to withstand the rigors of off-road racing and recreational punishment. The "no shock tower" design is a strategic choice for fabricators and high-performance enthusiasts who plan on using remote-mounted shocks or sophisticated coil-over setups attached directly to a roll cage or custom sub-frame. By removing the integrated shock towers, you gain unparalleled flexibility in your suspension geometry and mounting points. This beam is designed for use with thru rods rather than traditional torsion leaves, allowing for a smoother, more controlled range of motion that is essential for long-travel front ends. Whether you are building a ground-up tube chassis rail or heavily modifying a classic air-cooled floor pan, this beam provides the robust foundation required for professional-grade performance.

FITMENT

This wide-track king pin beam is intended for custom off-road applications and requires specialized components for installation. It is compatible with the following vehicle platforms and front-end styles:

• Volkswagen Type 1 Beetle: Pre-1965 models utilizing a King and Link Pin front end (requires custom frame head or modification).
• Sand Rails & Dune Buggies: All custom tube chassis configurations designed for King Pin front suspension.
• Baja Bugs: Custom builds featuring widened front clips and remote shock mounting systems.
• Woods Buggies: High-clearance builds requiring maximum front-end width for stability in uneven terrain.
• Note: This beam is 6 inches wider than stock and will require +3 inch tie rods on each side and the use of thru rods.

PRO TIPS

1. Master Your Steering Geometry

When installing a beam that is 6 inches wider than stock, you must account for the significant change in steering geometry. You cannot reuse your stock tie rods. You will need to source or fabricate tie rods that are exactly 3 inches longer on each side to maintain proper alignment. Additionally, pay close attention to ''''bump steer''''the tendency of the wheels to steer themselves as the suspension moves through its travel. Because this beam lacks shock towers, you have the freedom to position your steering box or rack and pinion in the optimal location to minimize this effect, ensuring a much safer and more predictable driving experience at high speeds.

2. Fabrication and Shock Mounting

The "No Shock Tower" design is a huge advantage for custom builders, but it requires a solid plan for shock mounting. Since the beam itself provides no support for the top of the shock, you must weld robust shock mounts to your vehicle''''s roll cage or a dedicated engine/chassis hoop. We highly recommend using high-quality heim-jointed shocks or coil-overs. When mocking up your mounts, cycle the suspension through its full range of motion without the thru rods installed to ensure that the shocks do not bottom out or over-extend, which can lead to catastrophic failure of the shock seals or the mounts themselves.

3. Transitioning to Thru Rods

This beam is specifically designed for thru rods, which replace the traditional stack of torsion leaves. Thru rods are essential for long-travel off-road front ends because they eliminate the internal friction and potential breakage associated with old-school leaf packs. When installing your thru rods, ensure they are properly lubricated and that your link pin bushings are in perfect condition. Since the thru rods do not provide the "spring" action themselves (unless you are using a specific torsion-bar style thru rod setup), you will likely be relying on coil-over shocks to support the weight of the vehicle. Double-check your spring rates to compensate for the added leverage of the wider beam.
