BMR Lowering Springs - Manufacturing Process Steps This was originally posted in August 2009. Most people don't realize how much work goes into manufacturing top-quality springs. BMR offers a LIFETIME guarantee against SPRING SAG. Here are the manufacturing steps used to make BMR springs:
1) BMR Springs are manufactured from chrome silicon high-tensile spring wire. This is the best spring wire available for automotive applications. Most NASCAR teams use this type of spring wire for their designs.
2) Every BMR spring is computer tested as the last step of the manufacturing process. Every spring...not just a sample from each batch. EVERY SPRING!! Each spring is loaded in the spring tester at the factory. The spring is compressed and the CNC Load Cell measures the force for a variety of spring lengths. The computer takes this data and compares it to the BMR quality specs. Bad springs (if any) are kicked out and the good ones are sent to BMR. Per our requirements, the test data for each and every spring is electronically sent to BMR.
3) BMR springs are cold wound on a CNC Coiling Machine. The CNC coiling head can adjust the spring diameter in real time to ensure that every spring is the same as the other springs. This guarantees that your right spring matches your left spring!!
4) Every BMR spring is compressed solid at the factory. Not once, but twice. This gives the spring its permanent set...and guarantees NO SAG. This allows BMR to offer a lifetime warranty against spring sag.
5) BMR springs are stress-relieved at 750 degrees F. This ensures that most stresses induced during the winding process are eliminated. This process is necessary to achieve the repeatable high-quality product that BMR offers!!
6) All springs are shot-peened to eliminate residual surface stresses. Many spring manufacturers skip this step. BMR insists on this operation as part of our spring manufacturing process.
A few more notes:
1) BMR springs are Proudly Made in the USA!!! Costs are minimized and quality is maintained using CNC manufacturing equipment. Shipping costs are low. No boats. No planes. No custom fees passed on to the customer. Just good old American manufacturing ingenuity!!
2) BMR springs are manufactured by a spring company that has been making springs for over 140 years. Think about it...when GM was founded in 1908, this spring company had already been making springs for 40 years. I say they know a thing or two about making springs.
3) BMR springs are manufactured by a family-owned spring company. The same family has owned this company for 140+ years (6 generations). No corporate bail-outs. No passing the buck. When your name has been on the door for 140 years, you make sure that you own the best spring manufacturing equipment available.
BMR Lowering Springs are the Highest Quality AND Lowest Cost spring available for the 4th Gen F-Body. Don't be fooled by companies that try to convince you to pay extra for your springs. With BMR, you get great tech advice, high quality springs, and the lowest cost!!
