About This

• Fit for Small to Medium Engines: This piston ring compressor kit features 7 different sizes of compression bands, covering piston diameters from 2-7/8" to 4-5/8" (73mm-117mm). Whether you're working on mid-to-large displacement motorcycles, agricultural machinery, or compact passenger cars and mini vehicles, this set provides the versatility you need
• Ratchet Self-Locking Mechanism for Effortless Use: The heavy-duty pliers feature an incremental ratchet system that allows smooth, slip-free adjustments. Once the correct size is reached, the handles lock securely in place, freeing both hands for precise piston installation. No more struggling to maintain pressure while aligning the piston
• 7 Band Sizes Included: 2-7/8” to 3-1/8” (73-79 mm), 3-1/8” to 3-3/8” (79-86 mm), 3-3/8” to 3-5/8” (86-92 mm), 3-5/8” to 3-7/8” (92-98 mm), 3-7/8” to 4-1/8” (98-105 mm), 4-1/8” to 4-3/8” (105-111 mm), 4-3/8” to 4-5/8” (111-117 mm), ensures uniform compression for fully seated rings, preventing cylinder wall damage
• Easy to Use: Simply place the piston into the cylinder, attach the correct size compression band, and then use the ratchet pliers to secure and compress it to the desired size. The band will help firmly secure the piston ring, and finally, tap the piston with a rubber hammer to quickly and easily complete the piston installation
• Built to Last: Crafted from high-strength steel with a black rust-resistant coating, this kit withstands repeated use without corrosion or wear. The extended handles are designed ergonomically, providing a comfortable grip while enhancing precision and hardness
