Second Hand Pros sells race car parts that are different from most other used parts offered for sale. These New or Good-Used racing parts are often from the top NHRA Pro Stock Teams and still have a tremendous amount of race-winning life left in them. NHRA Pro Stockers do not use their components until they are worn out or broken. Four qualifying passes and 1 or 2 rounds at 23 Events compared to buying used parts from Bracket racers who may make 6 or more runs a day, sometimes 3 or 4 nights a week, is like comparing apples and oranges! The successful PS teams keep accurate records and have strict maintenance schedules that they stick to! Tires, valve springs, clutch parts, transmission and rear end gears are all replaced while they are still functioning at peak performance. This is the main reason that it makes good sense to buy many of your race car parts from Second Hand Pros! Parts that might no longer be State-of-the-Art for a Top 10 NHRA Pro Stock are perfect for several other classes, and you reap the savings.
