Worth the price
Definitely worth every penny. I had a stalling issue in reverse mostly in my 89 chevy truck, and it started to get worse at idle. It would stall sometimes at a stop light and didn't seem to be getting enough fuel. I rebuilt the throttle body with new parts and seals and added this new spring since my old one had 250k miles on it. After that, it runs like a top. No more weak idle or stalling issues.

INSTALLED A REBUILD KIT AND ADDED THIS HIGHR RATE SPRING IN THE REGULATOR ASSY WITH A NEW DIAPHRAGM
THIS CHANGE MADE A DIFFERANCE THAT YOU CAN HEAR, FEEL AND SENSE. IMPROVED A VISIBLE FLOW PATTERN AND COMPLETED THE JOB WITH OUTSTANDING RESULTS. 350 TBI ENGINE NEED ALL THE HELP THEY CAN GET AND FOR THE PRICE I WISH I HAD BOUGHT A LONG TIME AOG. CRISP THROTTLE NOW AND THE OLD WHITE NIGHT WILL SMOKE THE TIRES ON DEMAND. LOL

Good spring with bad paint.
I put it in a spring rater and it was dead on at 14 pounds. The stock spring was sitting at 13 so it didn't solve the issue I believed I was having. The only thing I can knock on this product is that the yellow paint is of poor quality and was starting to flake off in it's packaging. A little bit of acetone and all the paint came off easily and I got a nice chrome looking spring. The truck doesn't feel any different with this spring so that can be a positive and a negative depending on what you were looking for.

excellent spring responce
installed on my 1988 chevrolet g20 van, it corrected my throttle lag when accelerating, now when I press on the gas pedal the van takes off like a bullet something it hasn't done in a year

Working well
1988 g2500 5.7 This spring fixed a real bad hesitation off idle when staring out even stalling once and a whileExpensive “spring” but it works great so far about 1,900 miles since installed really makes a big difference
