Description
BTR LS Piston Ring Compressor Tool 4.030" - BTRRC4030.4.030" - BTRRC4030 Bore 6.2 LS3 L99 LS9 L92 K9H L94.One piece aluminum tapered ring compressors have been around for some time, but BTR has made a significant improvement to the design. Rather than relying on the piston skirt to locate the pistons as they're being inserted into the block like one piece tapered ring compressors currently on the market, the new BTR ring compressors have a small but very important reverse chamfer at the bottom that fits into the chamfer at the top of the block which serves two functions..The lazer etching on a black background is easy to read and looks good even after lots of uses..In our beta testing against competitors tapered ring compressors, the BTR was easier to use and never caught a oil ring between the compressor and the block.
