Up locks will produce around .060" MORE Installed height then std locks
Hardened Single Groove Up Locks. Also known as "Offset Locks"
Application: 11/32" Applications
These are sold in half sets of 16 halves 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 reason to use up locks is when there isn't enough installed height w/ Std locks.
These will increase retainer height by around .060" over std locks.
Cautions: Up locks will raise the locks location on the valve tip. Engines using self aligning rockers, (LT1, Vortec SBC) will experience clearance issues between rocker rails and the locks topside.
Specially manufactured for added strength, our up locks are great for most performance single groove 11/32" valve applications in need of lincreased installed height.
If you look at the pictures, you can see the locator bead is offset.
NOTE 2- There are certain applications where additional attention to detail is required. Some applications might not have enough clearance between rocker arm and lock topside. Applications such as Late SBC Vortec and LT1 w/ self aligning rockers will most likely not have enough clearance.
