NOTE: Differences exist between some of the OEM  GM lifters. On a stock engine these differences do not usually cause any  problems but if you have a modified engine and your tolerances are at one end of  the range or the other, these differences can cause lifter pre-load errors. These lifters are the same  hydraulic travel and overall length (roller to pushrod cup)  as the production Z06 LS7 lifters and the GMPP lifters. This measurement should  be done by measuring from the tip of the roller to the inside of the cup. The cup  location should be measured using a pushrod with the same tip diameter as the  pushrod you will be using. Some LS2, LS3 and other Gen IV lifters may be 0.025"  shorter from the roller to cup and also in pushrod travel. As with any component change we recommend you check your installation  to make sure the lifter compression and pushrod length are correct.
