Since then we have grown into a research and development firm specializing in lightweight MONOCOQUE fabrication and suspension design.  Meeting the needs of both the corporate racing client and private street driver, Mason Engineering has a long history of designing. testing, and high quality fabrication.

We have developed products for use on the IMSA, Can-Am, G.T.P, LeMans, and the Indy racing series.

We have served as an in-house consultant to the racing programs of several major automotive corporations including Ford, Chevrolet, And Nissan.  We have worked extensively for these corporate team's engine shops, electronic labs, and wind tunnels.  We have spent considerable time in both dyno cell testing and chassis deflection testing.

Mason Engineering is OEM approved as a suspension product designer, manufacturer, and supplier for Indy Racing Teams.

Our products and expertise was used on the GM-funded solar powered experimental race car "The Sunracer" which won the world solar challenge in Australia in 1987.  Currently on display at the Smithsonian institute, the Sunracer used both our fabricated aluminum chassis and suspension.  When the 1942 Northrop N9M flying wing was restored to flying status for display at the "Planes of Fame" Air Museum in Chino, California, we were a key member of the Sheet metal restoration team.

We are designers and manufactures of award winning suspension and chassis parts all made proudly in the USA.  We never resell cheap imports.  This is our guarantee. 

Mason Engineering does not rely upon outside contractors to fabricate any part of our products.  All stamping, tube bending, and welding is done in our own state of the art manufacturing facility.  Only powder coating of the final completed item is done outside of our shop.  This allows us to maintain careful quality control to meet our exceptional standards.  The additional advantage of keeping all our work in house is that our rapid design development and fabrication brings our customers the latest designed product possible in the shortest amount of time possible.

Mason Engineering uses three types of materials, but our preferred material is aluminum, here is why.

Aluminum is one third the weight of carbon steel and stainless steel, and is twice as strong in a compression load situation.

The advantage of aluminum is it is light, and non-magnetic.  This means that electrical disturbances are reduced, and it resists corrosion.  In its natural state, aluminum has a clean appearance and absorbs impact loads without permanently deforming as aluminum has a high modulus of elasticity. Additionally Aluminum has a 45k PSI tensile strength.

Carbon Steel on the other hand is overall stronger in all directions of load but is three times as heavy, is prone to oxidation (rust), and is magnetic.  Carbon Steel has a 55k PSI tensile.

 Physical Properties of our materials:

 Carbon Steel:                           55k PSI tensile and 40k yield strength

 60601T6 Aluminum alloy:         45k PSI tensile and 40k yield strength

 Stainless Steel:              85k PSI tensile and 35k yield strength

 As you can see, stainless steel in the weakest of the lot but is good when used in heat affected areas.
