Classic Diesel Designs

The 7.3 Powerstroke owners asked for it, and we are here to deliver! Our stainless steel oil coolers for 1994-2003 powerstrokes are now in stock and ready to ship! We have also added our new "Super" magnetic 7.3 psd oil drain plugs which feature a strong enough neodymium magnet that it can lift your 1 1/4" wrench no problem! If you are a 7.3 powerstroke owner and just hearing about us for the first time, be sure to check out our complete 38 gallon tank kits, and our billet transmission dipsticks! Thanks for helping us keep the old iron on the road!
