MCB Performance - MCB Engine rebuild kits: STAGE - 3 ARCTIC CAT

MCB Performance has expanded our Stage Engine Kits to now include POLARIS! As you know MCB Performance has been focused on providing the finest engine components for many years. We have continued to grow and expand our product lines and further fine tune our Pistons and Internal engine components. In 2016 we completely upgraded our Engine Build program and it has already paid off with countless happy customers. Last year we heard loud and clear from our customers wanting the exact same quality components we use in our Engine program in a COMPLETE package so they can have a plug and play engine kit for the do-it-yourselfers. Customers wanted a simple few choices to match what they needed and we responded. These kits are available for just about every conceivable engine out there with more in the works. We have streamlined these kits now so that there are 4 options that are very user friendly:


Stage 1 - These are our famous Top-end kits that started MCB on its path. It has everything to do a top end including Pistons, Rings, Pins, Clips, and a Complete gasket set. These are available with MCB Classic series pistons or MCB Forged series pistons.

Stage 2 - This kit takes Stage 1 and adds a complete ready to drop-in Crankshaft kit. Make no mistake these cranks are trued and indexed to perfection using the finest Koyo and FAG bearings and genuine OE seals. This is our most popular kit and it's a great deal as a package.

Stage 3 - This kit includes everything in our Stage 2 kit, PLUS completely remanufactured and properly sized cylinders (or monoblock). This makes a TRUE major engine overhaul and ensures all parts are engineered to work together.

Stage 4 - This is MCB's most complete kit and comes with all of Stage 3 plus the following, OE thermostat, OE oiling check valves, Enough tubing to replace all the oil lines with premium grade non- hardening line, a tube of very specific case sealant, and full instructions including torque values and guidelines. All kits are available with the MCB Classic series pistons or can be ordered with the MCB Pro-Series forged pistons and available through this website or you can actually CALL and speak to a real person to place the order or ask any questions while rebuilding your engine.

More About MCB Engine rebuild kits: STAGE - 3 ARCTIC CAT

MCB Performance Core procedures and return / refund information 1 - What is a "good" core? A good core is simply one that can be re-conditioned to MCB standards. 2 - The core returned MUST be the same exact make, model, style and casting as the one you purchased! 3 - Crankshafts must be complete and ALL counterweights must not have any severe damage. We prefer the connecting rods also be usable but depending on the application we use new connecting rods anyway so that may not automatically disqualify the crankshaft. If the crankshaft is broken at a cross pin the crank may still be a good core because all pins are replaced when rebuilt anyway. The center gears are also typically replaced with new when available so that also does not always denote a bad core. Lastly, even with some damage to re-used components we will credit you the % of good parts. For instance if you have one counterweight heavily damaged of the 4 in a twin 2-stroke you will likely still receive 75% of your core refund, etc. 4 - Cylinder cores must be the same casting #. Cylinders must NOT be ported (we can simply re-plate your cylinders if this is the case). Cylinders must not be "sleeved" where they were not originally. Also core refunds will be reduced for the following: Stripped threads, broken skirts, and sealing surface damage and dings. We expect the bores to have damage and scoring and that is perfectly acceptable however if there are large cracks or transfer port cracks that cannot be accessed for welding the core is not usable. Cylinders that have been re-plated poorly or plated more that 3-4 times will generally fail in the process so keep that in mind. 5 - Packing your core for return is VERY important. This is often where additional damage occurs and can lead to losing your refund. A crankshaft is very hard to damage but a cylinder is EASY to damage. You MUST protect the cylinders' external surfaces (head surface, base, skirts, etc) when shipping the core back. We recommend wrapping the cylinder(s) in cardboard first and then putting the cylinder in a box thereby protecting it from drop page and other cores banging together as it travels. 6 - You MUST include your purchase information with the cores you are returning. We normally include TWO copies of you invoice when we send you your new parts with a note saying to send the 2nd copy back with your cores. Also if you are sending your cores from a location that has their business name on the label please have then add your name to the label if possible. 7 - MCB receives very large amounts of cores on a daily basis and it may take several days AFTER we receive you cores before we begin to process it. Please be patient and if you want to check it arrival check YOUR tracking # to verify its delivery. From that date you can expect roughly a 5-10 business day before you see the credit on your account. 8 - MCB will not be responsible for any loss of core funds if ANY of the above guidelines are not followed. Thanks for all your business - MCB Performance
