NEW PRODUCTS
DEFEO is ahead of the demand curve when it comes to creating new products for Allison Transmissions. We are not a typical parts supplier repackaging someone else's products. By having our own manufacturing facility, coupled with our own testing equipment DEFEO acts quickly when designing and creating our parts. Our state of the art testing equipment ensures that the parts we engineer are similar in form, fit, and function to their OEM counterparts. This vertical integration process and lack of a "middle man" ensures both quality and cost-saving solutions for our customers.
