Caltric 5136690 rear knuckles bearing bushings for Polaris Sportsman 550 X2 XP 2010-2014 are aftermarket parts designed to replace the original bushings in the rear knuckles of the Polaris ATV. Here are some pros and cons to help you decide whether to purchase these bushings:

1. Improved Performance: The Caltric bushings are made of high-quality materials, such as polyurethane, which provide better durability and performance compared to the OEM bushings. Polyurethane bushings do not wear out as quickly as rubber bushings and offer better stability and handling.

2. Reduced Noise: The bushings help reduce the noise generated by the ATV's suspension system. The polyurethane material is stiffer than rubber, which helps eliminate the slop and play in the suspension, resulting in a quieter ride.

3. Increased Longevity: The Caltric bushings are designed to last longer than the OEM bushings. They are resistant to wear and tear, and can handle the heavy loads and rough terrain that an ATV encounters.

4. Cost-Effective: Although the initial cost of the Caltric bushings may be higher than the OEM bushings, they offer long-term cost savings. The bushings do not need to be replaced as frequently, which means fewer repair costs over time.

1. Installation: Installing the Caltric bushings may require some mechanical skills and tools. The installation process can be time-consuming and may require additional labor costs if you choose to have them installed at a shop.

2. Cost: The Caltric bushings may be more expensive than the OEM bushings. However, the long-term cost savings and improved performance may outweigh the initial cost.

3. Ride Quality: Some users have reported that the Caltric bushings provide a stiffer ride compared to the OEM bushings. This may be a concern for those who prefer a more comfortable ride.

In conclusion, the Caltric 5136690 rear knuckles bearing bushings for Polaris Sportsman 550 X2 XP 2010-2014 offer several advantages, including improved performance, reduced noise, increased longevity, and cost-effectiveness. However, they may require some mechanical skills for installation and may provide a stiffer ride compared to the OEM bushings. Ultimately, the decision to purchase these bushings depends on your individual preferences and budget. If you value improved performance and durability, and are willing to invest in a high-quality aftermarket product, then the Caltric bushings may be a worthwhile investment. If you prefer a more comfortable ride or have limited budget, then the OEM bushings may be a better choice.
