This thing is awesome and clean. The only downside is you can't run a boot. No worries, I made a base that has a floating seal so the arm movement doesn't affect it. Just a little tweak and it's perfect.

I would definitely buy this product again

The typical return spring setup isn't always a good thing. With trying to locate each end without "reinventing the wheel" Simple to install and works great .

I installed it so that the brake pedal would fully return. Probably need to slightly modify the master cylinder push rod, as I did, but that is not a difficult task. The price and design compared to other return springs are the best.

Would Recommend

Should be advertised in all of the catalogs.

Having my master cylinder under the floorboard in my hot rod, I was having an issue with the pedal not returning all the way, causing the brake lights to stay on. I saw this spring in the Oval Track catalog and called tech support to see if this would work for me. Using the tech's tips, I installed it and it works great. I think this part should be offered in all the catalogs with the master cylinders. Thanks for your help tech support and Speedway Motors.

It says in the description for all master cylinders but it will not work on vacuum boosters. It is not big enough in diameter.
