Product Details

ProX 28.SIS4409-2 Valve and Spring Kit

Valve and Spring Kit

  • An alternative where the O.E.M. application uses expensive and less durable titanium valves
  • These steel valves offer increased durability and easily extends the lifespan to 3 times that of the O.E.M. titanium valves
  • Nitrided valves offer high microhardness while supersmooth surface finish reduces friction between stem and guide
  • Special stronger valve springs deal with the extra weight of the steel valves
  • Springs are made from premium chrome vanadium steel for higher performance and durability under high RPM
  • Fully rebuildable with O.E.M. retainers, bases and seals without the need of any further engine modifications
  • Intake and exhaust kits complete packages for quick, easy and cost efficient replacement

Very fast on line, and best price

Great Prices

I WOULD LIKE TO KNOW BECAUSE I WAS ON EBAY AND WAS DIRECTED TO YOU.. SO DOES IT MEAN THAT I STILL GET MY PURCHASE POINTS FROM EBAY.. AND THERE POLICY?? THANK FOR YOU TIME AND YOUR PRODUCT.. I STILL WANT TO PURCHASE THE KIT WHE IT IS IN STOCK..

So far I am pleased Got exactly what I ordered in good condition and quick delivery

Autoplicity had the item I wanted at a cheaper price than anybody online or in stores. They didn't have the item in stock, but they were very informative as to the status of my item. They have shown unheard of customer service via email since the inception of my order. I will definitely do business with them again.

Took me a minute to realize you applied the coupon code already.

Easy to use website and fast transaction and shipping.<br>Really great

Easy lookup and like style of shock listing

Autoplicity got my air filters shipped next day after I placed my order. Cheap prices, and good customer is what they stand for. I will definitely be looking at their site in the future for my car needs. <br>

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

Found what I wanted at the best price on the internet! Good tie-in with Amazon also.

This was my first time placing an order with Autoplicity and I would not hesitate to order from them again. The product was as described and shipping was very fast, received the item in 2 days. Good price too! Thanks Autoplicity.
