How Wide is a 55 Chevrolet Rear End?
The width of a 55 Chevrolet rear end is relatively unique, as it was only used in the 1955 model year and limited to certain models. The exact measurement for this specific rear end is 57-3/4 inches wide from wheel mounting surface to wheel mounting surface. It also measures 77-5/8 inches wide overall, including both axles and any additional components such as brakes or suspension pieces.
Depending on what type of car you are working with, the actual measurements can vary based on the options that were included when it was manufactured. Additionally, some enthusiasts like to modify their cars with aftermarket parts which could drastically alter these exact numbers. For those who are looking for an original 55 Chevy rear end however, this information should provide a good starting point!
What is the Ratio of a 55 Chevy Rear End?
The ratio of a 55 Chevy rear end can vary, but the most common ratios are 3.36:1, 3.55:1 and 3.08:1. The ratio you want to use depends on your driving style and needs; if you’re planning on doing some serious cruising or racing then you may want to go with one of the higher ratios for better acceleration and top speed, whereas if you’re looking for more power when hauling heavy loads or just need something that’ll provide good fuel economy then one of the lower ratios might be best suited for your situation. Generally speaking though, all three will work fine in any 1955 Chevrolet model so it’s really up to personal preference as far as which one is chosen in the end.
What’S the Difference between a 55 And a 57 Chevy?
The 55 and 57 Chevy are two of the most iconic classic cars in the world. They both feature a timeless design, with their stylish curves and bright colors making them instantly recognizable. Despite their similarities, there are some key differences between these two Chevrolets that make them unique from one another.
The 55 Chevy was produced for only three years (1955-1957) while the 57 was made for an extra year (1958). The difference in production time is reflected in many aspects of each car’s design: the exterior body shape, engine size, interior features, etc., all differ to varying degrees between these two models. On top of this, parts availability also varies greatly between these two vehicles; while it can be relatively easy to find parts specific to a 55 model due to its shorter production run and limited availability at dealerships over 60 years ago, finding original 1957 Chevrolet parts can be much more difficult due to its longer lifespan and greater accessibility during that period.
Ultimately both cars remain among automotive icons today thanks to their distinctive style and performance capabilities – but if you’re looking for something truly special then consider investing in a rarer vehicle such as a 1955 or 1957 Chevrolet!
