Jeggs has come a long way with reguard to diesel performance parts in the last year. They offer exhaust sytems both standard and stainless, fueling boxes, air intake kits and even replacement transmissions. I do alot of business with them every year, and have so since 1988. They all great to order from, they have such a big wharehouse that 95% of the time it is in stock and ready for shipment. I can call before 4PM and have it the next day, with standard shipping, I am only 150 miles from their shop. So far this year I have purchased a little over $8,000. 00 in parts from them alone. They and Summit Racing continue to be my favorite mail order shops. I hope more people on here give them a try, they have most items you would need at great prices and with excellent service. There main business is racing performance parts, but they handle a very large assortment of both racing, and performance parts for both the car and truck market. I have never had an order yet to get messed up, I like the conveniance of ordering off the internet, but for those who don't, they have a great sales staff that can take your order over the phone.
