Guys - These springs are a terrific deal !! No one will be disappointed with these 1.570" springs !! I have sold many sets of these springs, never a return or a complaint, you cannot go wrong!!!! This item is a complete set of lightly used Isky Tool Room Race Springs for a solid roller cam. Part number is 9989RAD. These springs are virtually new and have seen no abuse during their short lifetime. They were installed in an engine with less than .700" lift, they install at 2.000" and they bind at 1.130". They never got any closer to coil bind than .170", that's like a part time job for a race spring. (These springs were used in fire truck racers, very short drag track then hard on the brakes, very few runs per event and very few events per season. The springs are changed each season. Also relatively low lift cams and spring pressures. They come out of the engines looking as good as used springs can look. Check my feedback, I've sold dozens of sets with happy buyers every time !! This particular set of Isky springs is as perfect as any !! Any other questions, send me a number and I'll ring you up !!) I have checked each spring on my Rimac tester and they are within 5-10 lbs. of brand new springs, measuring 265+ lbs. at 2.000", the correct installed height. Open pressure varies from 700 to 710 lbs at 1.130", within 10 lbs. of new. New springs will cost you $570 or more, depending on your source. These springs are a terrific deal. Please contact me with any and all questions.
