Most of the stock AR springs I encounter in my shop are shot. After 25 plus years of providing support to the subchassis, most completely lack the ability to be fine-tuned. You will find using these upgrade springs will make adjustment of your subchassis much more painless. Heavy duty springs are intended for use only for exceptionally heavy platters/arms/weights.
Note: It is recommended that the existing studs be replaced at the same time you are replacing the springs. The longer studs allow for increased adjustment.
Specifications:
- Three matched heavy duty springs
- Three high-quality rubber grommets
