300 Below Inc. is changing the face of Motorsports by applying the deep cryogenic tempering and treatment process to increases engine performance, reduce wear and improve longevity. This one-time irreversible treatment improves the entire structure, not just the surface, and gives your engine the stability once found only in seasoned engines

Our process increases engine performance and engine lifespan through rearrangement of an engine’s molecular structure after utilizing our proprietary computer-controlled freezing process. Cryogenic tempering occurs after creating a significant increase in abrasive wear resistance and overall durability for an engine, resulting in improved tensile strength, toughness and stability within the metals. This helps release internal residual stresses, which were created when the engine was manufactured. Overall, our clients in the motorsports industry use cryogenic processing for stress relief, dimensional stabilization, increased wear resistance and durability for their engines and other high performance parts associated with the chassis. We help to create faster engines and offer our clients a significant competitive edge when racing against competitors with non-treated engines.

In short, the racing teams who have not yet discovered our cryogenic process find themselves at a significant disadvantage when racing against our teams who employ superior research and technology in their day-to-day operations. If you’ve seen racing on TV, it’s likely you’ve seen cryogenics in action. Racing teams in NASCAR, Indy 500, Tractor Pulling, and several other circuits call on 300 Below to give them the upper hand. Through our current non-disclosure agreements, we pledge to maintain secrecy for our clients and do not actively pursue their direct competition. If approached by a competitor, however, we maintain a policy that we will not discriminate against additional business. In keeping with this practice, and in the spirit of good sportsmanship, we will not reveal any secrets learned while working with past teams that could hurt their ongoing research and development efforts in racing.

Longer Engine Life

Higher Horsepower

Reduced Downtime & Breakage


There were no changes in dimensions (in our IH0986 Super Stock Pulling Tractor,) but performance has noticeably changed for the better … the engine starts much easier than before … our oil blow-by has dramatically decreased from 2-3 quarts per pass to only 1/2 cup. This motor has had a constant gain in performance since we started this season.

It keeps getting better… The HP and durability gains we achieved through cryogenic treatment … directly resulted in winning our first 7,500 lb Super Stock championship points race! I would recommend it to any racer in any motor-sport division who is looking for the newest edge in performance and durability.

Cryogenically Processed Race Car on Track going fast with speed.
This really has to be one of the greatest improvements ever for the racing community. Cryogenic treatment of the motorcycle and mini-sprint engines I build have given me many improvements. Engine builders tear down 2-cycles after 300 laps … I recently tore down a 250 2-cycle after 1,800 laps and found that I could measure no cylinder wear, no ring wear and only 1/1000th piston wear. The engines I have had cryogenically treated at 300 Below, Inc. have consistently out-performed identical non-treated engines.

Cryogenically Treated Racecar
We generally go through the motors after 1,000 to 1,200 laps. When we tore this engine down … the bearings were almost perfect and the crank looked like the day I installed it new.

Not only did (my Suzuki GSX-R 1100 motor) surpass my expectations, it blew them out of the water. I noticed improvements in compression, fuel economy, engine vibration and transmission shifting. I can’t wait to freeze everything I own.

We ran more than 40 races for the 1991 season between lower engine teardowns. Before cryogenic processing, we had to tear down after every six to seven events.”

Variety of Uses

  1. We have been deep cryogenically treating racing engines and transmissions for top racing teams longer than anyone on the planet.
  2. We started in Motor City in 1966. We are the best kept secret in racing. Top teams use cryogenic processing of engines and transmissions as a significant competitive advantage. They don’t want ANYONE to know they use cryogenic processing. Why? Because it works. Really works.

Have your blogs told you it’s BS? They are simply ignorant of the facts. Read the actual scientific peer reviewed research articles in this website. We have fought for truth for 40 years.

In fact almost every part in a engine assembly will benefit in one form or another from cryogenic processing. Multiple unique benefits accrue from a single process. Stress relief, stabilization, carbide precipitation, co-valent molecular bonding, and grain refinement all work together to improve an engines performance. Different types of metals in an engine all respond differently to the cryogenic process. Deep cryogenic processing increases horsepower and torque nominally, but it increases the life of an engine significantly. Less wear equals less cylinder taper, higher sustained compression and smoother engine components reduce adhesive drag. Bearings last longer, cams last longer, heads don’t warp, blocks stay square. Valves slide smoothly. Engines create less friction and therefor, less heat loss of energy and drag loss. As an analogy, the refined grain structure results in a surface contact more like glass on glass than sandpaper on sandpaper. It takes less force to spin the motor. The denser more coherent structure also transmutes heat energy more efficiently. Head temps run cooler. The result is longer life, more durability, more reliability, higher performance, and significantly lower costs from broken engine parts. To finish first, you must first finish. We have worked with racers for over 40 years. You would be surprised when people are fighting for 100ths and 1000ths of a second in drag racing what happens when they treat their motor with us. The entire cryogenic process for the entire engine assembly is less than the cost of 30 gallons of NitroMethane.

Cryo-Turbos Rock. Over 300% longer life.

A tractor puller with tri-sequential turbos pushing over 200 pounds of boost in a diesel, would lose 2+ quarts of oil in blowby into a catch can on a single pass.

After cryogenic processing the engine, same parts, same driver, same course, same tractor……….less than 4 ounces. Call us and let’s discuss a few real life stories and how we can help you.

We firmly believe that the nominal cost of cryo processing an engine is the best money you can invest in your racing career. If you are not pleased for any reason, we’ll send your money back. Give us a call. We are really good at what we do, and will do everything in our power to help make your racing a better venture. It works. 800-550-2796
