Factory bins that work

Whenever I'm that deep in LS (no head) and have done over 100,000 miles, I always swap out bins for peace of mind. A swirling lifter wipes the cam, it's just cheap insurance.

Pros
  • GOLS certified
Cons
  • Some little things

They will not fit if you keep your engine stock.

Does not fit Displacement on Demand engines. Don't buy this if you have the motor in stock. Good product just doesn't work with Active Fuel Management, bought these for my 2011 5.3 Silverado.

Pros
  • A sea of positive emotions
Cons
  • Crumpled packaging

Original equipment is always the best.

If you overhaul the engine. You don't want to do that twice. Some parts are best used with original equipment. This is one of them. It fits perfectly and holds the lift rollers in the correct position on the camshaft, securely and without play. Worth a small extra charge.

Pros
  • One year trial period
Cons
  • Some disadvantages

2004 Chevrolet Silverado 5.3L

They were perfect, they fit right on the jacks and slid into position like a bug in a carpet. The ones I removed were awful and didn't hold up well on the elevators, they looked like fakes. Do yourself a favor with this part, buy an OEM part because this small plastic part is a very important part in keeping your engine running properly.

Pros
  • Great design
Cons
  • Good but not great
