The .585” Lift COMP Cams Beehive Valve Spring Kits for GM 6.6L Duramax Diesel Engines include everything needed to upgrade from stock springs: Beehive Valve Springs, steel retainers, spring seats and valve seals. Beehive Valve Springs feature a reduced diameter at the top of the spring to allow the use of a smaller and lighter retainer, reducing overall valve train weight. The lighter valve train combined with the stronger spring allows the engine to rev higher without concerns of valve float while an increased spring rate maintains valve train stability at elevated RPM to allow the use of more aggressive camshafts. The unique ovate Beehive shape not only has higher load but is more dynamically stable than the factory spring, ensuring valve train stability at elevated RPM and boost pressures.This Part Fits:

Excellent!!
Color: Beige, Size: Large
Really loved these shirts for my hubby. They were pretty good quality shirts. Love the linen material. Also love the buttons on the collar which my husband prefers to wear with his jackets. They are very comfortable. As far as size, I ordered according to the size chart. He typically wears a size Large. According to the size chart an XL would best so that’s what I ordered. But I truly believe that a size L would’ve been better. So I would say they are true to size. My husband weighs 205, and has muscles and a size L would’ve been just fine. I ordered 3 because I loved them. I’ll stay with the XL. But if I were to order more I’ll preorder a Large. Very happy with this purchase. They are not slim fit either. Just for an FYI.

Quality + Fit + Value - VERY pleasantly surprised!
Color: Black, Size: Large
I stand at 6.0125" 200lb (showing signs of a Dad bod)., and the large was a perfect fit for me. The quality exceeded expectations, perfect thickness and weight for the colder months. I actually set this up between a Boss & Ted Baker (my-go's to in past 10-years) and asked my date to pick one of three - she grabbed this shirt.
if you're looking to re-evaluate how much your spend on dress shirts - this Brand will not disappoint in terms of quality and fit. If your wearing brands like Express, Banana or even worse - Untuck-it, consider this a marginal upgrade.
I'm going to by a few more and I'll update if anything changes.

Great shirt
Color: Beige, Size: Medium
Great fit, seemed like thin to medium weight fabric which is perfect for him. Lil with any linen blends, they wrinkle so it is more of a casual wear. Washes great and is super soft when wearing.

Trashed after one wash
Color: Beige, Size: Small
It’s a great looking shirt. The price is good. The fit is good. But it’s so scratchy that it’s like wearing a potato sack. And after washing it ONCE it pilled so bad that I had to throw it away because it looked like an electrical sander had been used on it. But this is what Amazon has become: bad quality everything.
