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. Choose a spring rate and adjustability that fits your driving style, adjust the valving to match and you are on your way. These shocks also utilize a fully threaded body that allows you to adjust your ride height for the perfect stance or to finely tune the weight balance for superior handling. Specially designed for QA1's Pro Coil Systems, the American-made lightweight high travel springs have fewer coils and a smaller wire diameter, resulting in increased travel due to the larger distance between the coils. They reduce unsprung weight and react faster, optimizing suspension performance. Multiple spring rate options are also available and have been successfully tested in various applications, from casual street driving to hard core race applications.

Great Quality and Value - Perfect Connections
Size: 10 Pairs, Pattern Name: Banana Plugs
I used these Monoprice 24k gold-plated banana plugs to connect both my surround sound and desktop speakers, and they work perfectly. The connections are solid and secure, with no looseness or signal issues. They’re easy to install, look great, and offer excellent value for the price. Highly recommended!

Fantastic speaker plug at a great price!
Size: 5 Pack, Pattern Name: Banana Plugs
This is a product that gets the job done effectively, and at a good price. Banana plugs are used to clean up speaker wire - you can generally screw in speaker wire, but banana plugs provide a nice interface that allows you to plug in and remove speaker wire as needed. These closed plugs do a good job terminating / hiding the wire. They fit very well into various components and amps that I own. INSTRUCTIONS to install / use them: * Remove around 1" - 2" of the white casing to expose the red and white individual speaker wires * Strip each wire so ~1/2" metal is showing * Make sure the plug end is screwed in tightly (this does not need to come out) * Unscrew the base of the plug from the other end * WithOUT twisting the metal wiring, insert the wire (match wire color with plug color; start with either one) from the bottom of the plug until the metal sticks out the top * Have ~1/4" metal hanging past the plug * take the wiring and drape it down the sides of the plug (just the smooth side, do NOT cover any of the screw threading or it will be very hard to close it) * Spread the draped wiring around the plug as evenly as possible (makes it easier to screw in later) * Screw the two ends of the plug back together (the side with the draped wiring will go inside the plug) * If you get stuck while screwing it back in, unscrew and adjust the wiring * Repeat for the other side, and you're done!

pretty good banana plugs
Size: 5 Pack, Pattern Name: Banana Plugs
i bought these over 6 months ago and i just installed them to the front left and right floor standing speakers - sony ssf-7000 i have them for over 10 years hooked up to a yamaha 7.1 AVR. alot of people have had trouble installing this - one single banana plug comes in 3 parts - the bottom and top (the banana plug tip) can be unscrewed. what i did was tightened the top first (top being the tip of the banana plug) then unscrew the bottom off completely - make sure you have like 3/4" - 1" (depending on your gauge of wire) of exposed speaker wire that is straight - then thread it through the hole at the bottom up - i then rolled the exposed 3/4 - 1" exposed copper wiring into a ball that is bigger than the hole of the banana plug bottom piece so the wire doesn't fall back through where it came from. then i screwed on the top and middle piece back with the bottom piece - tightening it a bit so i know there's good contact. also make sure the tip is screwed in all the way as well as a double check. what you don't want to do is have the copper wire touch the threaded part of the bottom piece - the wire will cut off from the screwing action. i plugged it into my sony speakers and it wasn't a real snug fit - a bit too loose to feel secure - it didn't seem to go all the way in - but it fit fairly well in my receiver. my intention was to use these banana plugs with my 2 channel set up but i decided to go pre-constructed mediabridge 12 AWG speaker cable instead - those fit my 2 channel set up on my receiver and elacs really snug and secure. i tested it and it works fine. i didn't hear any loss of signal or any extraneous noise. none of my (14 awg?) wiring fell through the bottom and it sounds good. so no complaints there. i bought 5 pairs - but i find that it is an odd number to include a package - even numbered pairs would be better. anyway they seem constructed well - easy enough to install and they do work. thanks for reading
