Your Power and Modification Source for '71-'93 Power Wagon, Ram, Ramcharger, Trailduster, and Cummins Trucks.
* NEWS FLASH - ASA is moving! After several years in business we are moving down the street to a bigger and better facility. We have been very busy these last few months getting everything in order and now we're moving equipment. Please be patient with us as we'll be involved with large-scale logistics for a while. We are happy to continue consulting and are taking orders but will be working at a slower pace for a while until things settle down. We surely appreciate your patience during the transition. - Sam (Mad Max)

At ASA, classic Mopar trucks get a second chance. Very little is available in the aftermarket for the old-school Mopar rigs, and we are dedicated to keeping our old iron on the road and working better than new.
We test and perfect our products on our own vehicles before anything is sold to the public. Our current specialty is Cold Air Intakes for 1989-1993 "1st Gen" Dodge Cummins Trucks. Over 150 sold, our high-quality Intakes are in production and ready for purchase exclusively from Piers Diesel Research:

At ASA we take the time to listen to our customers, making sure you get exactly what you want, not our version of it. We fabricate your parts to your specifications and the options are limitless.
Here's some eye candy -

Anything is possible at ASA - From the ultra-custom to the standard upgrades, if you can think of it, we can do it.
We recently made a trip to Moab, UT to test a prototype air bag suspension system on our '78 Ramcharger, the "Macho Nacho":
The RC has been in development for almost three years, and nearly every portion of the truck has been modified in some way, the biggest mod being the air system. We liked it so much we're going to do a similar air bag system on our '93 Cummins rig. The Cummins' system will be designed for very high towing capacity verses the RC's huge flex and articulation - it is all about the needs of the customer and tailoring the truck to meet those needs. At ASA, we listen closely to what your goals are, and will put 110% towards meeting or exceeding your expectations.
Producing parts that fit is important - our goal is producing parts that fit and work. Every item is tested for quality, endurance, and performance to ensure your accessories perform and last as long as you own your truck.
Thanks for visiting ASA. Keep 'em on the road.
