Command the trails and dominate at the track with any of the Polaris RZR engine performance accessories from Everything Polaris RZR! Complete Polaris RZR engine upgrade kits by companies like KT Performance can give you that added oomph you're looking for, but you don't have to conduct a full-blown engine rebuild to your motor in order to make it more effective. Some RZR 1000 owners go with big bore kits to expand the size of their cylinders, while others choose to port and polish their heads, add oversized Ferrea engine valves, and throw in valve spring kits by companies like Kibblewhite. But regardless of whether you're wanting new head gaskets for your Polaris RZR 900, or bigger Bosch 2200 injectors for your RZR Turbo, you'll find what it takes to extract every last bit of power from your UTV's engine here at Everything Polaris RZR! From CP-Carrillo connecting rods and turbo pistons to pre-welded cranks and AEM coil packs, nothing is spared when you go through Everything Polaris RZR for performance Polaris RZR engine parts, performance Polaris RZR engine kits, and other performance Polaris RZR engine accessories!

Polaris RZR engine kits and engine rebuild kits are great for riders with defunct motors, and few aftermarket part providers offer better Polaris RZR engine rebuild kits than Everything Polaris RZR! But regardless of whether you’ve got a 2019 Dynamix EPS edition of the RZR XP 1000, or a 2018 Polaris RZR Trails and Rocks edition, we’re sure to have the performance engine parts and engine rebuild components you seek at Everything Poalris RZR. Although it’s not a performance engine part per se, the Polaris RZR 75 amp alternator kit by ZRP products is great for those who’ve experienced a lack of voltage during a race or ride through the woods. The stock Polaris RZR stator often struggles to keep multiple accessories powered at one time, which can then lead to error codes being thrown and the machine’s limp mode being initiated. This can all be avoided, however, with the bolt-on Polaris RZR alternator kit by ZRP Products!

In addition to aftermarket alternators, Polaris RZR engine performance parts like crankshafts, gaskets, cylinders, and pistons are also commonly used in RZRs that are built for speed. A straightforward way to increase the power of your RZR motor is to make it bigger. But instead of putting in a larger engine, you can instead expand the size of your existing engine with a Polaris RZR big bore kit. By having bigger engine cylinders, more fuel can be combusted with every stroke, and as such, more power is generated. Add a few millimeters to the diameter of your engine cylinders and you’ll be amazed at the effect it has on HP. But when you bore out the engine cylinders in your RZR or get larger aftermarket Polaris RZR cylinders, you’ll also need appropriately-sized pistons, crankshafts, gaskets, and bearings. And instead of buying all these Polaris RZR performance engine parts separately, you can get them in a single Polaris RZR big bore kit from Everything Polaris RZR!

Building the perfect Polaris RZR engine with all the bells and whistles is one thing, but ensuring that the existing engine parts, engine components, and engine subsystems harmonize as a single unit takes precision control. The performance electronics firm AEM makes a programmable engine management system that is perfect for performance Polaris RZR engines, and there are other programmers, chips, and ECU tuners available that will also help to seamlessly integrate the various engine modifications you've made to your machine. Many riders want the power of a Turbocharged Polaris RZR, but prefer the length and width of the RZR 900 or RZR 1000 for more nimbleness when trail riding. And while ECU tunes, aftermarket exhausts, and clutch kits can help to wake your side-by-side up, there's only so much you can do without adding Polaris RZR performance engine accessories. And the best place to fulfill all your engine-related needs is right here at Everything Polaris RZR!

From Polaris RZR engine bore kits to Polaris RZR engine programmers, you’ll find almost anything you require for more engine power and extended engine longevity here at Everything Polaris RZR! You should never neglect proper engine care, engine maintenance, and engine upkeep with high-grade engine oils, engine filters, and engine fluids, but when you develop an itch for greater engine performance hat you just can’t scratch, let us help with the performance Polaris RZR engine parts and accessories at Everything Polaris RZR!
