Dialing in your front-end geometry is just as critical to lowering lap times as dropping in fresh engine pistons, which is why serious racers searching for reliable new kart parts demand the Performance Manufacturing Inc. (PMI) 10-Degree Right-Hand Caster Block. Engineered for chassis that require aggressive turn-in bite, this right-hand caster block (MPN: PM-19SLR10) forces the inside tire down while lifting the outside, jacking weight efficiently across your go kart axles. The included 1/2" spherical bearing eliminates the binding and slop found in standard bushings, ensuring that every micro-adjustment you make at the racing steering wheel translates directly to the track surface. Built with a heavy-duty focus on durability, this block withstands the brutal lateral loads of high-speed ovals and technical sprint tracks without deflecting.
Precision Geometry for Your Racing Steering Wheel
A 10-degree caster split provides the aggressive self-centering and camber gain needed to keep your tire's contact patch flat during heavy cornering. When paired with its left-hand counterpart, this block delivers a symmetrical, highly responsive steering feel that reduces driver fatigue over long feature races. In the highly competitive world of kart racing, reliability is just as important as raw speed. A failed steering component can end your weekend instantly.
Built to Outlast Standard Go Kart Axles and Components
Machined for exact perpendicularity and structural rigidity, the PMI caster block acts as the rock-solid foundation of your steering yoke. Whether you are tuning a heavy LO206 setup or a high-horsepower two-stroke, the integrated spherical bearing maintains ultra-low friction pivoting heat after heat. By upgrading to a premium caster block with a built-in spherical bearing, you are investing in lap-after-lap consistency. The aerospace-grade materials and tight machining tolerances ensure that your front-end geometry remains exactly where you set it, even after aggressive curb strikes or wheel-to-wheel contact.
- 10-Degree Caster Angle: Maximizes front-end grip and aggressive weight transfer during corner entry.

- Right-Hand Specific: Designed to pair flawlessly with the left-hand block for balanced chassis tuning.
- Heavy-Duty Construction: Resists deflection under extreme lateral G-forces for consistent handling.
- Friction Reduction: Outperforms standard bushings by eliminating steering bind under heavy loads.
- Fast Pit Adjustments: Streamlined yoke mounting allows for rapid caster calibration between heats.
Frequently Asked Questions
Q: Why choose a 10-degree caster block over an 8-degree version?
A: A 10-degree caster block provides more aggressive weight jacking. It is ideal for tracks where you need more "bite" on turn-in or for chassis setups that require additional help lifting the inside rear tire to rotate the kart through the corner.
Q: Does this caster block come with the bearing installed?
A: Yes, the PM-19SLR10 includes a high-quality 1/2" spherical bearing. This replaces standard bushings to eliminate steering slop and binding, providing a much smoother feel at the steering wheel.
Q: Is this caster block compatible with all kart chassis?
A: This block is designed for standard karting spindles using a 1/2" kingpin bolt. While it is a universal-style performance part, always verify your spindle geometry and kingpin diameter before installation to ensure proper fitment.
Q: How do I know if I need a Right-Hand or Left-Hand caster block?
A: Caster blocks are side-specific to ensure the caster angle is oriented correctly for the steering geometry. This is a Right-Hand (RH) block; ensure you pair it with the corresponding Left-Hand block to maintain balanced front-end handling.
Q: What maintenance is required for the spherical bearing?
A: Keep the bearing clean and free of track debris. Periodically check for any play or "notchiness" in the movement. If the bearing becomes stiff or develops slop, it should be replaced to maintain precise steering feedback.
