Durability is key to the health of your engine, and it is for this reason that you should always look at purchasing only the best LS7 lifters. You may well be able to find cheaper hydraulic lifters than what Malex Motorsports stocks, but there’s a reason why we won’t stock them; the cheaper materials that they’re made out of will feature softer metal, which wears more quickly, and furthermore, sometimes oiling of the roller can be an issue as the shape of the lifter body may distribute the oil away from the roller and cam lobe.
The grand sum of this is that the internal parts of the lifter can also let go, and that will cause the lifter to collapse internally. The check valve of the hydraulic lifter can also leak causing the lifter to bleed back when the engine is off.
Malex Motorsports stocks the best LS7 lifters because they are genuine GM parts. Not only does that mean that they are easy to install, but you can be sure that their durability will be vastly superior, and this will help you to look after your engine.
