3/4″ Car Clamp Kit

(34 customer reviews)

$26.99

This easy to install car exhaust manifold stud repair clamp is a great alternative to replacing rusted or broken exhaust studs. The Studfix clamp reattaches your exhaust down-pipe and flange to your manifold by hooking over your manifold’s ear, simply tighten the provided nuts and say goodbye to your noisy exhaust. Installation requires no redrilling, no removing old studs and our clamps are more secure and easier to install than comparable c-clamps.

  1. D. Parker

    Repaired broken stud on 1987 Chevrolet Caprice Classic. Installed in 10 minutes, worked as advertised. Make sure you measure for the 3/4″ clearance before buying and that you have a big enough ear on the manifold to hold the clamp. Highly recommend,would buy again.

  2. Mark Reeder

    Worked great on my 89 Chevy Astro RV. perfect fit….easy fix. Would recommend to save money and time.I cant believe these are not in every auto parts store.

    The exhaust studs broke on my Expedition and I knew I had an expensive fix ahead of me. I was looking for new studs and came across this product on Amazon. I decided to give it a try. The product arrived exactly on time. The product is straightforward and instructions were simple. I am not the most mechanical guy but was able to install these in about 30 minutes. Most of the time was spent grinding down the broken original rusty studs a bit which I did with a dremel tool. The product worked perfect and after a month it is still perfect. Would DEFINITELY buy again.

    Great product! I have a 98 expedition, the product worked well for one side, the other side had a huge head on it and the product wouldn’t fit! But it’s recommend these to everyone they saved me a ton of time and money!!!

    Quick fix!

  11. KQuality

    Love it

  12. Bruce Timbrell

    Worked as promised

  13. Norman Peterson

    Worked great for three out of the four broken studs. Got the last one with a little modification, bending. Saved a lot of time and potential cost in the long run. Would use them again if the need arises.

  14. D1CSS

    fit well, 1997 f-150, 4.6 li, with over 300,000 miles this is just the option the customer needed [conventional repair would be more than the truck value].

  15. Scott Bartlett

    Worked very well. Keep in mind the broken bolt has to be ground down flush. This is a snug fit.

  16. Almighty dub

    Worked great!

  17. Henry R Delong

    saved me from replacing the manifold. That would of meant the junk yard for this old Ford.

  18. Scott DIckerson

    perfect fit!!!

  19. Ivan

    Really easy and strong fix !

  20. beasy

    Worked very well for my 97 F-150.

  21. eman

    This item saved a lot of time and aggravation. Used it on a 1948 Chevy pickup truck. Yet to see how it works over time, but so far it looks really good. Thanks for this simple fix.

  22. Amazon Customer

    I recently put a clutch rebuild kit in my 99 ford explorer sport. I had to cut the flange bolts to the driver side exhaust manifold. While on explorerforum.com I saw a link to your product and instantly purchased it. I couldn’t be happier, it is such a beautifully simple solution to a very annoying problem. Thank you!

  23. Eric

    Worked perfect on a 1997 Ford Ranger 4.0 V6

  24. wendy

    very impressed

  25. sam arbogast

    awesome fix

  26. Amazon Customer

    Easy to install and worked very well

  27. Chris

    Will buy these whenever needed! Installed on my 2000 4×4 ford explorer xlt with the v6 sohc engine . To remove the old studs use a Dremel with a extension wand and the black heavy duty cutting discs. Remove the front wheels and the plastic shielding covering the side of the motor. Be careful to not cut your oil filter. Tops of studs need to be removed too to allow room for clamp. Be sure on passenger side that clamp does not interfere with oil filter.

  28. Chris

    Genious. I’d like to shake the hand of the person who decide to make and sell these. A very good product. Worked great on my Ford Explorer.

    Saved me MONEY! Exactly what I was expecting! Fit great.

  31. any

    Was replacing transmission and and broke bolts on exhaust manifold needed new bolts. Worked as advertised good as OEM.

  32. Danno Cardinalon

    This product rocks!!! 2010 Kia Forte

    I am amazed! This product made my life a lot easier!!

    While you may need a couple of exhaust spacers to use the product correctly, I would definitely recommend this product.

    I used two exhaust flanges, ears at 90 degree apart, a small ring i made out of exhaust pipe, slapped it in, put it where it belonged, used the Studfix, and it just worked great!!

    I installed it on my 2010 Kia Forte with 2.4 l engine. Like many quick fixes, sometimes it’s not as easy as plug and play. You have to improvise and not be afraid of cutting.

  33. John MacWilliamson

    Great product. Worked as advertised.

  34. Amazon Customer

    Definitely works. I had some old bolts on a 1994 Ford Ranger v6 4.0 exhaust manifold that had to be torched off or busted. No way to use the old threading. These stud clamps worked like a charm. Fit easily around parts of the old bolts stuck in the manifold, and stayed on much easier than I thought they would while putting the Y-pipe back on. I trust these things more than I trust other stud clamp options, especially better than those stud clamps that work like a C-clamp. The less moving parts, the better.
