Carburetion:
 
Thunder Products manufactures and distributes a full range of carburetor tuning devices that make jetting easier, more efficient and provide increased performance and power.  We specialize in making your existing carburetor work better.

Dial-A-Jet - Dial-A-Jet is like adding fuel injection to your carburetor that you can richen or lean by turning a dial,  giving you altitude and temperature compensation, increased performance and fuel efficiency.

IntelAJet - Rejet your machine "on the fly" right from the handlebars.  Altitude and temperature compensation, improved performance and fuel efficiency.

Thunder PowerJet  - Gives you a huge range of adjustment on your main jet circuit.  Manual adjustment for altitude and temperature.  Works on stock machines as well as Turbos, nitrous and blowers.  Improves performance and fuel efficiency.

VIP (Velocity Intense Performance) - NEW - Reduced Price! -  Eliminates "erratic idle syndrome".  Instant, quick throttle response.  Performance improver for 38mm and 40mm rack style Mikuni carbs.

UFO (Ultimate Flow Optimizer) - Makes the VM Mikuni roundslide out-perform the flatslide carbs up to 13/16 throttle opening.  Gains 1 1/2 hp per 100cc of engine size on 2 stroke engines and 1 hp per 100cc of engine size on 4 stroke engines.  This is a true legendary product.

Injector Perfector - Increases fuel efficiency and horsepower on fuel injected Arctic Cat snowmobiles.  Low price - High Performance

Jumbo Jets - Extra long main jets for the RX-1 Yamaha snowmobile.  Eliminates flame out on steep climbs.  Special sizes made for turbo, blower and nitrous set-ups.

Easy Tune Pilot Air Screw Adjuster  Easy way to adjust your 38mm and 40mm Mikuni rack style carbs with your fingers.

HotWires - Big increase in your ignitions firepower for a small price.  Improves performance and starting.  AVAILABLE FOR SNOWMOBILES, ATV'S AND MOTORCYCLES.

Airbox:

TPI (Total Performance Intake) Valve  - Makes an adjustable high performance air box out of your standard one.

Uni Filters - The #1 selling high performance air filters in the world.  Why pay more for less?

Polaris Air Box Synchronizer Kit - Makes sure your carburetors are synchronized by equalizing your airbox pressure in each carburetor.  If you don't have this kit, your carbs are not synchronized.

Clutching:
Thunder Products manufactures and distributes the Thunder Shift™ and Heavy Hitter clutch kits - the #1 clutch kits in the industry.  We produce kits for Arctic Cat, Polaris, Comet, Quad Cam, Yamaha, and Ski-Doo TRA clutches.  TRA kits include the racer endorsed Thunder Shift Arms, Thunder Shift Pin Kits and Thunder Shift Rollers.

Thunder Shift Kits  - Available for Arctic Cat, Polaris, Comet and Yamaha smaller to mid size snow machines and Polaris ATV's.  This is the only way to get the maximum power to the ground.  Inexpensive, easy to install and use.  Full technical support available.  The best buy in clutching!

Heavy Hitters - Simply the best clutch kit in the entire industry (No smoke and mirrors, revolutions or wild claims).  We don't change this every year, we got it right the first time.  This kit is for mid size displacement up to and including the biggest and badest sleds.  Highly tunable for stock to full mod units.  Easy install and tuning.  Professional tech support.  This kit ROCKS!  Available for Arctic Cat, Polaris, Yamaha and Comet clutches.

Thunder Shift Ski-Doo TRA Arms, Pin Kit and Rollers - These kits changed the way Ski-Doo had been clutching their machines for 50 years.  All the race teams now use this concept!  Ski-Doo has always been first out of the gate, but gets rundown on top end.  This kit is still first out of the gate but gains an amazing 10 mph plus on top end with an arm stretching midrange.  An absolute must have for top performance!

TRA Belt Adjuster - Now you can adjust belt clearance on a TRA primary easily and cheaply!

Glide Washer Kit  - Take the spring out of your front clutch and notice that the spring is gouging its way into your clutch cover and spyder.  This spring is working compressionally as well as torsionally.  Install glide washers to stop the wear and get smoother, more consistent clutch shifting.  It's A NO BRAINER! Available for: Arctic Cat, Polaris, Ski-Doo, Yamaha

ABC Kit (Additional Bearing Contact) for Arctic Cat Clutches - The ABC kit gives you a 400% increase in bearing contact on the clutch cover.  This results in quicker and smoother up-shifting and back-shifting as well as longer clutch life.  The ABC Kit has a built in belt adjuster.  No need to take your clutch apart to adjust your belt to sheave clearance.  Simply turn the adjuster nut to the desired setting.  This gives you improved performance and longer belt life.

TPI 911 Response Clutch Cover for Arctic Cat, Polaris and Yamaha Clutches
The billet machined aluminum TPI 911 Response Clutch Cover turns your ordinary OEM clutch
into a high performance, long life, premium clutch assembly.

Other:

Ultra-Q Silencers - Most units are within 5% of standard DBA levels with lower throatier sound (no high pitch whining).  Gain power and lose weight.  Great looking Cerama-chrome finish that improves performance while keeping heat out of the hood area. Professional fit and quality, quick easy install and complete warranty.  Available for Arctic Cat, Polaris, Ski-Doo and Yamaha.

Tachometer/Hour Meter - Finally, a tachometer and hour meter that is affordable with quartz accuracy ranging up to 9000 rpms.  Small (2 1/2" x 1 1/4") and easy 5 minute install.  We dare you to find a better tach at 2 to 3 times the price.  Only $38.00

LeakProof Motorcycle/Dirt Bike Fork Seals - The best fork seals in the industry.  If you are going through all the work of changing your fork seals, why wouldn't you use the best.

Heat Loc Hand Guards - Protect your hands and keep them warm.  For use on Snowmobiles and ATV's
