1.260" VALVE SPRING SINGLE W/DAMPER 1.750 @ 131.5 LBS / MAX LIFT .550 = 16PCS
These were used with a Clay Smith Flat Tappet cam # 01-012 H-274-8-B and aftermarket cast heads. The quality of these springs are stellar. The specs are within +/- 2% of advertised data. These springs were tested for free height prior to a 10 stroke full compression to coil bind. The initial free height was around 10% differential, after test they all came within 2%. Spring pressures were tested at varying installed heights, and 3 different lift options, all were consistent. Coil bind height was measured and reflected advertised height and below. Finish is good, not shiny, but respectable. Packaging was more than adequate and arrived in great shape. Shipping was a little slow, but really no different than the rest of the industry. I would recommend these springs for a cam requiring the appropriate pressures. My only complaint is that the purchase did not include a sticker! LOL. Will provide additional feed back after these have run for a bit.
