The Legacy
July 19, 2023
It's a Family Affair!

Jessica Kastner has been in the aggregate industry since she was knee high to a grasshopper. Her father, Joe Kastner, was in the business for 32 years, and took Jessica to quarries when she was growing up. So, she knows a thing or two about rocks. She started KastRock nine years ago with her father back in 2014, and she loves her job and KastRock.
The Journey Continues
Joe retired a few months back and Jessica is excited for her father to have less stress, but admits it is bittersweet. Taking on the entire business was a huge leap, and she has handled it with grace and style. KastRock is Jessica’s passion because as she says, “It is not just a job, it’s a legacy.”
Family Matters Most
In her off-time Jessica spends it with her family riding four wheelers and ATVs. She has two children, a daughter Kassidy who is 14, and a son Kayson who is nine. Both of her children also do jiu jitsu, and really enjoy it. Her daughter aspires to go into law and her son dreams of being a truck driver or welder.
Jessica Rocks!
Jessica makes running a business in the aggregate industry look easy, and that’s because she learned from the best, she has an excitement for her job, and what she gets to do every day. She is a female leader to look up to and watch out for, because she’s definitely going places.

When crusher repairs or scheduled maintenance are on the horizon, one of the most common questions aggregate producers ask is whether OEM parts are truly worth the investment. While lower-cost aftermarket options may seem appealing upfront, the long-term value of the right replacement part often goes far beyond the purchase price. At KastRock, we help customers make informed decisions that support uptime, production efficiency, and total cost control. If you are evaluating replacement components for your crushing equipment, this guide explains the real value of Metso OEM crusher parts and when they may be the smartest choice for your operation. What Are Metso OEM Crusher Parts? OEM stands for Original Equipment Manufacturer. Metso OEM crusher parts are designed and produced to meet the exact specifications of the original crusher model. These parts are engineered for compatibility with Metso crushing equipment and may include: • Jaw crusher wear parts • Cone crusher mantles and concaves • Impact crusher blow bars • Bearings and bushings • Hydraulic components • Seals and hardware • Mechanical assemblies • Electrical and control system components Because they are built to original standards, OEM parts are intended to deliver consistent fit, performance, and reliability. Why Crusher Part Quality Matters A crusher operates under extreme loads, vibration, and abrasive conditions. Even a small variation in part dimensions, metallurgy, or tolerances can affect machine performance. The wrong replacement part can lead to: • Reduced throughput • Poor product gradation • Premature wear • Increased power consumption • Installation issues • Unexpected downtime • Damage to surrounding components Choosing quality crusher parts is about protecting production, not just replacing worn items. Key Benefits of Metso OEM Crusher Parts Precision Fit and Compatibility One of the biggest advantages of OEM crusher parts is proper fitment. Components designed specifically for the original machine help reduce installation issues and support intended operating clearances. This can shorten maintenance windows and help your crusher return to service faster. Consistent Performance Metso OEM parts are engineered to perform with the crusher’s original design parameters. That means wear parts, mechanical components, and chamber profiles are developed to support efficient crushing performance. This often results in: • Better throughput • More consistent product size • Improved reduction ratios • Predictable wear life High-Quality Materials and Engineering Crusher components experience intense wear and stress. OEM parts are manufactured using materials and processes selected for those demanding environments. Depending on the application, that may include specialized alloys, heat treatment standards, and wear profile engineering that supports longer service life. Reduced Risk of Secondary Damage A lower-cost part that fails early can create much higher costs later. Misfit or underperforming parts can accelerate wear on shafts, frames, bearings, and other expensive components. Using properly engineered OEM parts may reduce the risk of avoidable collateral damage. Are Metso OEM Parts More Expensive Up Front? In many cases, yes. OEM crusher parts may carry a higher initial purchase price than some aftermarket alternatives. However, purchase price alone does not tell the full story. The true cost of a crusher part should include: • Expected wear life • Downtime during replacement • Lost production from failures • Labor costs • Damage to related components • Product quality impacts • Frequency of replacement A part that costs less but fails sooner may end up costing more overall. When Metso OEM Crusher Parts Are Definitely Worth the Cost Critical Components For high-value internal components such as bearings, shafts, bushings, hydraulic assemblies, or precision mechanical systems, OEM parts are often the preferred option because reliability matters most. High-Production Operations If your plant runs at high tonnage or has tight production schedules, downtime can be extremely costly. OEM parts can help support consistent uptime and predictable maintenance intervals. Specialized Crushing Applications Operations processing hard, abrasive, or difficult material often benefit from parts engineered specifically for that crusher and application. Warranty or Performance Requirements Some operations prefer OEM parts to align with warranty expectations, service planning, or fleet standardization. When Aftermarket Parts May Be Considered There are situations where quality aftermarket crusher parts can be an option, particularly for non-critical items or older machines. The key is ensuring the supplier has a proven reputation, strong quality standards, and dependable support. Not all aftermarket parts are equal. Extremely low-cost options can carry higher risk. How to Compare OEM vs Aftermarket Crusher Parts When evaluating replacement parts, ask these questions: • What is the expected wear life? • How accurate is the fit? • Is metallurgy suited to my material? • What downtime risk exists if the part fails? • Will this affect crusher performance? • Is supplier support available quickly? • What is the real cost per ton processed? This approach often leads to better decisions than comparing price alone. How KastRock Helps Customers Choose the Right Crusher Parts At KastRock, we understand that every crushing operation has different priorities. Some customers prioritize maximum uptime, while others focus on budget planning or lifecycle cost reduction. Our team works with producers to identify the right parts strategy based on: • Equipment model • Material type • Production demands • Maintenance schedule • Budget goals • Lead time requirements Whether OEM crusher parts or another qualified solution makes sense, we help customers make practical, informed decisions. Final Verdict: Are Metso OEM Crusher Parts Worth the Cost? The answer is yes! When uptime, reliability, performance, and equipment protection matter, Metso OEM crusher parts can deliver value that extends well beyond the purchase price. The lowest upfront cost is not always the lowest operating cost.
