These QA1 GM Pro Coil Systems are available for 1971-1996 Impalas and Full Size GM vehicles, including Full Size Chevy, Buick, Oldsmobile and Pontiac models, and are a great option for anyone looking for fully adjustable ride height and valving control.

Worked Great. Save a Near New Tire
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I got these because twice this year I picked up a nail in my motorcycle tire. The local shops want to sell tires so they won't patch any tire no matter how new. I used these on two tires, a steel-belted radial and a bias-ply off-road tire. It worked out great, both have been holding air for months now and by doing it myself I saved hundreds of $$$. These are the best way to pemanently patch a tire that's gotten a smallish puncture.

Good quality, Best for schools and shops.
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
I bought this butyl repair patch and the quality is good. I brought it to the school where I’m learning automotive repair and used it as a teaching consumable. Many students tried it, and everyone thought it worked very well. One thing I would suggest for individual buyers: pay attention to the size combinations in the package. For most car owners, you may end up using only one size more often. Because of that, this mixed-size packaging is probably more suitable for schools, training programs, or auto repair shops where different sizes are needed regularly. Overall, it’s still a good quality product and performs exactly as expected.

Look very useful
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Haven't actually used them yet, but they look like the perfect way to fix a flat. As can be seen they come in various sizes depending on what you will need. All you need to get is some tire patch rubber cement and a good inner tire sealer (I picked up a can of Xtra Seal)

Saved me from buying a tire
Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch, Size: 0.16 x 1.42 ,0.24 x 1.77 ,0.35 x 2.36 Inch
Took our ancient van on a trip to Florida (from IL) and wouldn't you know we picked up some debris in construction. I was able to plug it however the next morning it was flat again. This time I used 2 plugs to and we were able to get home on that. Realizing this wasn't what I wanted my wife driving around and I didn't wanna buy tires for a van with 250k on it I set out to find some internal patches. I pulled the tire off using a harbor freight bead breaker and some motion pro spoons, used vulcanizing Compound and a dremel and patched it right up. Once the tire is off its a really easy process and I just marked my tire and rim to keep the balance close when it went back together. All appears to be working perfectly with no leaks over the past few weeks. This cost way less than a new tire and now I have more for other holes in the future
