DIESELSITE boots are designed to replace leaking and deteriorated sets on the 7.3L Ford PSD light duty diesels.
Our boots are made of a more durable material and have a stronger hold for trucks making higher boost numbers. Higher boost in the PSD can stretch the limits of a saturated set of factory boots and could blow your boots right off. In some cases, even stock or under-powered vehicles will experience boots that slip and lose grip if they've lost integrity and are saturated in oil.

THE ISSUE WITH STOCK BOOTS:
Stock boot material is silicone; however, this type of material is NOT oil compatible. This material will break down over time in these applications as the PSD incorporates a closed crankcase vent system. This means oil travels through the intake and comes in constant contact with the boots. This oil contact causes deterioration and leaks due to the incompatibility of the silicon boots and the oil from your crankcase. In fact, if you have seen an oil mist all over the valley of your PSD and wondered where it was coming from, chances are it was caused by leaking and deteriorated stock boots. The stock boots WILL leak air and oil and cause a 3-4 PSI loss in boost.
