COMP Cams is proud to announce another industry first: a bolt-in-ready Bushed Shaft Rocker System for GM LS engines. Thanks to innovative engineering, this patent pending Bushed Shaft Rocker System increases valve train stability and durability while decreasing deflection and providing bolt-in convenience for LS1, LS3 and LS7 cylinder heads. The COMP Cams Bushed Shaft Rocker System improves valve train stability and durability by securing all eight rocker arms onto a single rocker shaft. Thin tri-layer rocker arm bushings reduce rocker arm deflection and eliminate the high Hertz loading that can occur in needle bearing equipped rockers. Reduced rocker deflection increases valve train stiffness, ensuring that your LS is more efficient and durable under high loads. COMP Cams engineers worked to ensure long-term valve train durability by perfecting rocker to valve stem geometry and provisioning for supplementary pressurized oiling via threaded ends on the rocker shafts. Additionally, each rocker shaft is Plasma Nitrided, further increasing the system’s durability even when used with aggressive solid roller valve trains. The COMP Cams Bushed Shaft Rocker System for GM LS delivers high-level valve train stability, precise fitment, truer valve train geometry and increased load-bearing capacity in a package that is ready to bolt in that requires no machine work.

This company lies to you. Ordered a 02 sensor from APPD for my C7 Vette. Paid the highest possible courier service for the fastest possible shipping from Newcastle to France. I needed the part urgently. Ordered at the weekend and called them Monday to confirm all was in hand and explained the part was required urgently. Response from APPD yes we've recieved the order and will ship as soon as its been processed. Called every day for the next 7 days to be told yes its been shipped and this is the shipping number. Turned out it took them till Friday ..5 days later to post it and then the package lay at the courier another week or so. APPD lied to me throughout this whole transaction. The package cleared customs in 2 days and should have been with me in just over week and not over 4 weeks. APPD offereed the postage refunded after I had to start a PAYPAL dispute.. This should have been a straight forward simple part delivery.When it goes wrong you shouldn't lie to your customer. A serious compay would refund the customer not try to fuzz the truth and blame everyone else. I refused the postage delivery refund so you can buy some honesty pills and discuss with your team how to avoid more negative service feedback. If your thinking of ordering parts from APPD scroll on and find another supplier. You dont need or want the hassle of dealing with these people.

Over a month waiting on parts and all I get is it will scan soon week after week. Reordered from US so I could finish build and same parts arrived in one week. Waiting to see if they will refund??

placed an order for parts 13th of feb, all listed in stock, got shipping update for label created on the 16th of feb. I have still not received what I ordered and paid for, no updates. I have been getting the same generic answer "order will be fulfilled today" for nearly 2 months now when trying to enquire. Quite disappointing as I have been unable to finish off my car due to waiting on the final fuel system parts for over 2 months now.
