Summit Machine’s Extra Large Flex Joint is now back in stock! This joint has a wide 3″ mounting width and can be rebuilt like all Summit flex joints. Outer housing is from 3″ x .250 DOM making it extra heavy duty.
Now available in two bolt sizes: 5/8″ or 3/4″.
Joints are $54.99 each. Tool is $13.99 each.
Over the week end I was able to get back to the Twin I-Beam project. I machined the top and bottom of our prototype kingpin knuckle. I had already machined out the mid section a couple weeks back. Here are some pics of the progress.
Yes, that’s right! NITRO CIRCUS made a visit to Summit Machine. Something about Jim having his eye worked on triggers them to need us….strange coincidence. (It was right after Jim injured his eye last year they came by.) Anyway, last time we did some work for them it was to make some chromoly passenger foot pegs on Travis’s motorcycle and some sturdier “axles” for their “big wheels”. This time it was making some camera parts for their production crew. Pretty cool nonetheless, and thanks so much to Mike for working his tail off this weekend to get the parts done.
Summit Machine’s prototype GM Ecotec intake adapters. Designed to smooth out the airflow when a 3 inch intake tube is used with the GM ecotec “drive by wire” throttle body. They are currently being tested on the class4 and class1000 buggies of Blakley Bros. Racing, Hold Fast Racing, and SPS Racing.
Here are some pictures of Summit Machine’s 9ii assembly. The threaded holes on the sides of the housing are for the mounting brackets. All threaded holes have been fitted with stainless steel thread locking threaded inserts. In the last picture the oil system ports are visible. These ports spray oil directly on to the ring gear.
We now have in stock 3/4 inch Heim Joints with 14mm Reduction Spacers. Designed to replace the 3/4 inch heim joint with a 14mm though hole commonly used in Rock Krawler and Pure Performance lift kits. Spacers can be used with a more readily available 3/4 inch heim with 3/4 inch though hole. Making it easier to find replacement heim joints when you need them.
First picture is a side plate anodized and ready for bearings and seals. The second picture is the gear cover also anodized in everyone’s favorite color Purple. It’s one of the colors in our logo so I saw it fitting. Looking back on it I’m not sure that was the best idea. The third and fourth pictures are more of the stub shafts. This time with most of the black scale from heat treatment removed.
A few more pictures of Summit Machine’s 9ii (9 inch independent). The first is of the gear cover before anodizing. To get the shape I desired the outer perimeter had to be surfaced machined. Second picture is a close up of the bottom of the housing. Again extensive surface machining was involved to achieve the complex shape desired. The third picture is the stub shafts fresh from heat treatment.
Here are a few pictures of Summit Machine’s 9ii (9 inch independent). It was designed and manufactured in house at Summit Machine. The housing, gear cover, and stub shaft retainers are machined from aircraft grade USA made billet 6061. The 9ii was designed to be as narrow as possible while retaining a standard 9 inch differential and gear set. Width between the Size-21 (934) CVs is less than 13 inches. The acrylic gear cover was used only to test the oiling system designed into the gear cover.
Pictured is the Summit Machine High Tensile Strength Restraining Strap Clevis. MD MotorSports was bending and breaking their restraining strap clevises every race, due to the angle they were mounted on their Class 1 car. Instead of cutting up the chassis and remounting them we made some out of High Tensile Strength Heat Treated Chromoly steel. Several hundred race miles later and they are still straight.
