Description

COMP Cams Valve LocksEb Mach Stl 7Deg S - Set of 100Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock.

Most people believe that the tang inside a valve lock holds the retainer and valve spring in place while the engine is running, but this isn't the case. The cross-section of material in the tang is not strong enough to withstand open spring loads of 1000 lbs. or more. The sole purpose of the tang is to temporarily locate the lock, retainer and spring relative to the valve until the taper of the retainer can nest around the outside surface of the lock. This creates a collet effect that binds the two together. The more spring force exerted on the retainer (as the valve opens), the more force applied by the collet effect to keep the retainer and lock in place. With the emergence of valve sizes other than the standard 5/16", 11/32" and 3/8", it is important to make sure the valve locks match the valve size. There should always be a small gap between the two halves of the lock when they are properly positioned on the valve stem. If the two halves fit together without a gap, they are too large. If the locks fit tight to the stem and leave a gap between the middle of the lock and the O.D. of the stem, the locks are too small. Our line of stock replacement 7 valve locks for stock engine rebuilds are recommended only for street applications with lighter valve spring loads and are stamped and hardened for superior wear resistance. Also available are machined 7 locks and titanium Super 7 Locks for some applications. They offer the same valve spring location accuracy as our Super Locks without the need to change to 10 degree retainers.

Nice to have
Size: 3 Tier Black-31.5"W
This cart is nice for party. It is easy to assemble and use for multi-purposes. The best part is it has wheel and makes it so easy to move the cart around and hall things in/out for part or gathering. The 3 tiers make space for can carry a lot of items in the cart all at once. The quality is very good. Is just a very useful cart to have in the house.

Sturdy
Size: 5.9"D, Color: Rustic White + Honey Brown
Works great, rolls well. Well put together, pieces fit, not lopsided, does not feel like it will shake apart in a second. Fits all the laundry detergent bottles I need, although I don’t use the jumbo sizes. It is antique white, looks a bit distressed; while I like it, it may not fit everyone’s decor so take a good look at the picture.

Perfect cart Perfect fit !!
Size: 5.9"D, Color: Rustic White + Honey Brown, Size: 5.9"D, Color: Rustic White + Honey Brown
Put this cart together a few days ago. It took me, alone, about an hour. I’d say this cart is extremely well made!! Good to follow the instructions. Made assembly very easy. The frame and wheels are very stable and rolls very smoothly. Holds a fair amount of my bathroom products. I did consciously not attempt to make the cart hold more than it should although it’s very strong. It fits perfectly in the space between vanity and wall. I was going to put a piece of marble on the stained wood top but the finish is nice enough that I decided to appreciate the warm wood finish. Definitely recommend this item!!

Not Incredibly Stable
Size: 5.9"D, Color: Rustic White + Honey Brown
The storage cart was fairly easy to put together and looks nice. It's one of few that I've found to fit such a narrow space. Wheels roll well, but only move forward and backward. The cart will tip over if not fit in a small space that forces it to hold position. Works well for my space, but giving a 4 star rating due to that fact it will tip over easily.
