Review SPI T moly Piston Kit Polaris Cleanfire Standard Bore 85mm fits HO 800 2017–2019

SPI T-Moly Piston Kit for Polaris 800 HO Cleanfire Standard 85mm (Part Number: SM-09287)

The SPI T-Moly Piston Kit is specifically designed for Polaris 800 HO Cleanfire snowmobiles with the standard 85mm bore (models from 2017 to 2019). This kit is an excellent choice for riders seeking top-tier performance and durability for their sled. Let's explore the features of this outstanding piston kit in detail.

The core component of the kit is the piston itself. Crafted using T-Molybdenum Alloy, these pistons exhibit superior heat resistance, strength, and durability. Compared to traditional aluminum pistons, T-Molybdenum pistons can withstand the high temperatures produced by modern snowmobile engines without the risk of failure. Moreover, their enhanced strength results in improved piston-to-wall clearance, ensuring better ring sealing and engine efficiency.

Another essential piece in the kit is the ring set. The ring set consists of compression rings, oil control rings, and wrist pin bushings. Precision manufactured to fit perfectly inside the piston, these rings deliver excellent sealing, enhanced compression, and controlled oil consumption for optimal engine performance. The wrist pin bushings, made from high-quality materials, not only provide a smooth operation but also offer improved durability and reliability.

Lastly, the piston pin and wrist pin retainers round up this comprehensive kit. The piston pin is machined from high-strength steel to handle the demanding conditions encountered in snowmobiling. Alongside this, the polymer wrist pin retainers contribute to a quieter and smoother engine operation by reducing engine vibrations.

In summary, the SPI T-Moly Piston Kit (SM-09287) promises exceptional performance and durability for your Polaris 800 HO Cleanfire standard 85mm snowmobile. By leveraging T-Molybdenum alloy for the pistons, premium ring sets, piston pins, and wrist pin retainers, this kit upgrades your sled's engine to a whole new level. Make your Polaris not only faster but also more reliable with this outstanding piston kit customized for your vehicle.

SPI T-Moly Piston Kit for Polaris 800 HO Cleanfire Standard 85mm (2017-2019): A Detailed Analysis

The SPI T-Moly Piston Kit (part number SM-09287) is a popular upgrade for Polaris 800 HO Cleanfire Snowmobiles from the years 2017 to 2019. Upgrading to this kit offers several advantages and disadvantages, which are discussed below:

1. Enhanced durability: T-Molybdenum pistons provide increased strength and resistance to wear compared to standard pistons. This results in longer engine life and fewer repairs.

2. Increased power: The t-moly pistons can handle higher compressions efficiently. This leads to improved engine performance, improved throttle response, and increased horsepower.

3. smoother operation: The molybdenum material allows for better heat dissipation, reducing the risk of detonation and pinging. This results in a smoother, more consistent power delivery.

4. reduced threats of hydraolic lock: The piston kit features enhanced oil control rings, which help to reduce the risk of hydraulic lock. This issue can cause engine damage due to a lack of lubrication.

1. Higher cost: The SPI T-Moly Piston Kit is more expensive than standard piston kits. Considering that the cost of purchasing and installing the kit can be substantial, it might be a significant investment for some riders.

2. Limited applications: The SPI T-Moly Piston Kit is only compatible with Polaris 800 HO Cleanfire Standard 85mm engines (2017-2019). If you own a different snowmobile make or model, this kit may not be suitable.

3. Potential for cracking: Molybdenum pistons are more brittle than standard pistons. Although they are more durable as a whole, the increased brittleness may increase the risk of piston cracking under heavy use or extreme conditions (e.g., extreme temperatures).

4. Complex installation process: Replacing pistons requires specialized tools and knowledge to ensure proper installation. It is recommended to have the piston kit installed by a professional mechanic.

The SPI T-Moly Piston Kit for the Polaris 800 HO Cleanfire Standard (2017-2019) has its advantages in terms of increased durability, power, and smooth operation. However, its disadvantages, such as the high cost, limited compatibility, potential for cracking, and complex installation process, should be carefully considered before making a purchase.

If you frequently use your snowmobile for demanding conditions, Seasoned riders or those seeking to extend their engine life and achieve better performance may find the upgrades offered by the SPI T-Moly Piston Kit worthwhile. However, those on a tight budget or who rarely push their snowmobile to its limits may find the investment unnecessary. Ultimately, your choice depends on your personal riding style, snow conditions, and the importance you place on power, durability, and cost. Please consult your snowmobile dealer or a professional mechanic for expert advice and guidance in making a decision.
