Are you looking to get the most out of your Genral 1000, RZR 1000S, 2015-Up RZR 900, or 2013-Up Ranger 900? This motor kit has been proven to produce actual results that make big horsepower. On the national racing level, this package outperforms so much that competitors have tried to tech us for cheating. NOPE! It’s simple… the homework has been done and we’ve created the most badass engine package available. The stock platform is alright, but they left so much airflow on the table. We start off by changing out the small exhaust valves with larger ones, then porting your head to our proven specs. We then add our high performance camshafts which have higher lift and a great profile to make huge all around horsepower gains. Next we add heavy duty valve springs, valve seals, new spring bases, retainers, HD buckets, and shim your valves. This means we switch you out to a regular shim under bucket style adjustment, and we do the valve shimming for you. All you need to do is simply install the head and time your cams. Kit is meant to be ran with 91 octane pump gas, no race gas required.

We can also do a full motor build for you! Professional disassembly and assembly of this motor would add $600 to the build cost.

Looking for a race fuel motor? We can go high compression with a hotter timing curve and gain another 5-6 HP on 110 octane.

Our exhaust system and Custom programmed Bully Dog GT are necessary when running this kit. Our Stage 2 clutch kit is also highly recommended and is necessary unless you already have adjustable clutch weights. The BMP 935cc big bore kit also works extremely well on top of this kit showing another 5-6 HP and big torque.

Looking for less? We can eliminate any components from the AirXtreme package for those just looking for a big valve head. Please contact us for more information and pricing if this is something you’re interested in.

***Please send your head in with valves assembled, and cams bolted in with all cam caps. Please remove your intake boots and cam gears. Package carefully and insure package accordingly!***
