This redesign alleviates the old problem of the lifter getting blocked and the resulting tick as the lifter can no longer attain its full pressure to work properly. The 3rd gen lifters will stop the lifter tick, that is so common on the 6G72 engine.
We and 3SX share the same supplier for these. Trusted part for the 3000GT/Stealth community.
*****We personally run these exact lifters on my forged build, Sold 100s worldwide, Imported from USA. Purchase with confidence*****
