I haven't weighed mine, but it is definitely heavier than the previous standard hood I had on the car. I also have to use a prop rod to keep the hood open as the AG hood will overwhelm the springs. 7813684-AGHood.jpg (58 downloads)

My buddy bought a used set of hinges...I am rebuilding them....could these possibly do the same thing as the old ones? Any tips on making them tighter short of re-bushing the hinges?

I have been told that AG hoods used heavier springs. Don't know if that's true or a wive's tale, but the springs on the old hinges from my standard hood will NOT hold the AG hood open.

The springs on my car now hold the hood up fine. Perhaps I should count the coils? '71 GTX N96 auto 3:55 '74 Challenger 440+6 4spd 4:10 '71 Duster 340 auto 4:10

Which I'd certainly consider if I was drag racing the car, but since mine is simply a cool street cruiser I'll stick with the heavy but COOL air grabber hood. And now be looking for a set of Charger hood hinges/springs!

YES, they are very heavy! My car is clone from a purple 318 Satellite. It got the Road Runner treatment and the air grabber hood back around 1991 before anybody even used the word clone to describe these cars. The Satellite springs must have worked okay for all previous owners, but when I got the car in 2005, the springs were getting weak. I had Resto Rick rebuild my hinges and they held the hood up great for a year or so, then it went right back to the way it was before. Rick was nice enough to hook me up with a set of the correct springs. I took a picture of the two different springs while my buddy and I were swapping the springs out. If memory serves me, the longer spring is the plain Satellite hood spring.

The metal also appears to be slightly thicker. I think you can actually see the difference in thickness in the photo. Last edited by pinkduster; 08/14/13 07:51 PM.

Correct, I just looked thru the factory parts books on the 71/2's, hood spring pn# 3586092 was used on 71 Chargers with or with out fresh air hoods, PN 3586088 was used on Sat/RR/GTX non air hoods, PN# 3586092 (Charger) was used on 71 RR/GTX with fresh air hoods...FYI the 71 4dr and wagon Satellites had a different part# all together even though those models had a full hood,...so the 71-4 Charger hood spring is what you Air Grabber guys need for your Plymouths Mike

Anyone know how is the quality on this product? https://www.aarqualityfiberglass.com/cart/product_info.php?cPath=188_41&products_id=690
