Quick Answer

The 15-degree front caster block from Vanquish Products is a lightweight, anodized upgrade that increases caster angle on your Vaterra Twin Hammers, improving steering return and straight-line stability. Follow the steps below to install it correctly.

Why Caster Angle Matters

Caster angle is the angle of the steering pivot when viewed from the side. A higher caster angle increases steering self-centering and straight-line stability, which is especially useful for high-speed runs and rough terrain. The stock blocks on the Twin Hammers have a lower caster angle, so upgrading to a 15-degree block can make the truck feel more planted and responsive.

Keep in mind that a higher caster angle can slightly increase steering effort at low speeds. If you mostly crawl slowly, you might prefer a more neutral setup, but for mixed driving, the 15-degree block is a balanced choice.

Installation Steps

  1. Remove the front wheels and suspension: Start by removing the front wheels and then disconnect the upper and lower suspension arms from the axle housing. This gives you clear access to the caster blocks. Common mistake: Forgetting to support the chassis can cause the suspension to droop and make reassembly tricky. Keep the suspension components organized to simplify reassembly.
  2. Detach the steering knuckle assembly: Remove the steering knuckle from the caster block by taking out the pivot pins or screws. Carefully note the orientation of all parts. Common mistake: Mixing up left and right components can lead to incorrect caster angle. Take a photo before disassembly for reference.
  3. Remove the stock caster blocks: Unbolt the stock caster blocks from the axle housing. Clean the mounting surfaces to remove any dirt or old thread lock. Common mistake: Leaving old thread lock on the bolts can prevent proper seating. Use a wire brush or solvent to clean the threads.
  4. Install the new 15-degree caster blocks: Position the new Vanquish caster blocks on the axle housing, ensuring the 15-degree angle is oriented correctly (usually with the thicker part toward the rear). Hand-thread the bolts to avoid cross-threading. Common mistake: Installing the block backwards will reduce caster instead of increasing it. Double-check the orientation before tightening.
  5. Reassemble the steering knuckle and suspension: Reattach the steering knuckle to the caster block, then reconnect the suspension arms. Tighten all bolts to the recommended torque, but avoid over-tightening as it can bind the suspension. Common mistake: Over-tightening can strip threads or cause binding. Use a torque wrench if available.
  6. Test steering and alignment: Reinstall the wheels and lower the truck. Turn the steering left and right to check for smooth operation and verify that the wheels return to center. Common mistake: Ignoring binding or rubbing noises can lead to premature wear. If steering feels heavy, re-check the caster block orientation and bolt tightness.
