Product Details

ARP 300-8245 Perma-Loc Rocker Arm Adjuster - Pack of 16

One of the more aggravating things found in many high performance engines is constantly having to re-adjust rocker arms. Until ARP introduced the patented Perma-Loc rocker arm adjuster, there wasn't a "poly lock" on the market that you didn't have to continually tighten. There are several important reasons why ARP's exclusive Perma-Loc rocker arm adjusters won't loosen like others. First, the adjuster body is heat treated all the way through (not simply case hardened), which eliminates the thread "movement" common to others. Secondly, the threads are machined exactly perpendicular to he bottom of the adjuster, so it seats evenly and applies pressure on a full 360 degree circle. Lastly, the set screw is machined flush on the bottom, not pointed, so it will have optimum contact on the rocker arm stud. Perma-Loc adjusters are also easy to use, because the compact 12-point head is designed to hold your wrench in position while you lock the set screw with an Allen wrench.

  • Designed for aluminum rockers, and features an overall length of 1.200, a thread size of 7/16 - 20, and a body diameter of .550; sixteen adjusters per package
  • Bottom is flush-ground perpendicular to the threads, so it seats evenly, and the set screw has flush-machined tip for optimum contact and seating on stud
  • Threads are precision CNC-machined exactly perpendicular to the bottom of adjuster to ensure an optimum seat, even pressure, and maximum engagement
  • Forged in-house from grade A 8740 alloy chrome moly steel and heat-treated throughout for a 190,000 psi tensile strength, not simply case hardened like others are
  • Exclusive 12-point head, with special shouldered "stop" to hold the wrench, eliminates the need for special adjusting tools

Great Company with awesome support!!

Wish Canada or Amazon.ca carried these anchors. Maybe you could look into that. A follow-up would be appreciated since the information does not show the weight of your item, hoping it is only 4 pounds for us old goats :)

Autoplicity always has the lowest prices and they ship extremely quickly!

The price as well as the turn time for receiving my product was great. I placed an order late Sunday evening and I have received my order by Wednesday of that week. I still can't get over how great the price was for the bike rack I ordered compared to all of the other sites out there.

This was my first time using autoplicity and I was very happy with their service. Great prices and fast shipping.

I was a little concerned at first. They advertise same-day order processing, and they said my part was in stock. However, my order took three business days (plus the weekend) to finally ship. As long as the right part arrives, I'll be happy. The price was $100 less than everywhere else, so that can't be beat.

Shipped in a fair amount of time and customer service was easy to contact.

Good prices and quick shipment

Great experience! I placed my order on Sunday and my programmer arrived on Thursday - with ground shipping. I unpacked the programmer and it functioned exactly as I had hoped. I will definitely consider purchasing from Autoplicity again!

These guys have the best prices I could find by far, for the parts I needed. I have made two purchases from them so far and am sure there will be more. They ship fast and provide tracking information.<br>

Completely amazed by this seller. I recieved the rack in just 2 days and the price was unbeatable. I'm just stoked to have finally found a bike rack worth having!!

Super quick service! Great price and I received the product the day after I ordered it.
