Product Description

Up locks will produce around .010" MORE Installed height then our std Green locks

Hardened Single Groove Up Locks.

Application: 11/32" Applications



These are sold in half sets of 16 pieces which is enough for 8 valves. If you need enough for 16 valves, simply order quantity of two.


We carry a few variations of offset locks. Some for more installed height and some for less.

Up locks are designed to offer MORE installed height. These can be a real problem solver when not enough installed height is available using std locks.

The main purpose of using up locks is when there isn't enough installed height w/ Std locks.

These will increase retainer height by around .010" over our std green locks. *(see note at bottom of page)

Cautions: Keep in mind that anything which moves the retainer upwards will result in less rocker to retainer clearance.

* Be aware that std locks can vary from one vendor to another therefor, the actual amount of height change may differ based on what they're being compared with as well as other factors such as how the locks contact the valves groove shape. When compared to our hardened Green locks, this batch is producing around .010" more installed height. If you have our green locks, you'll most likely get at close to .010" more installed height with these. How much installed height increase you get may vary. Due to variables out of our control, we offer no guarantee of exact height change.
