Product Description
BTR 4.075" Piston Ring Compressor | Precision Tapered Ring Installer Tool
Fits 4.075" Bore Engines | Aluminum Tapered Design | Reverse Chamfer Alignment for LS Builds
Take the frustration out of piston installation with the BTR 4.075" Piston Ring Compressor, engineered for precision, ease of use, and reliability during engine assembly. Built from high-quality aluminum, this one-piece tapered ring compressor features a unique reverse chamfer design that sets it apart from traditional compressors. This innovative feature allows the tool to locate perfectly within the cylinder bore chamfer, ensuring accurate alignment while significantly reducing the risk of oil ring damage during installation. Whether you're assembling an LS-based engine or any 4.075" bore application, this BTR compressor delivers a smoother, faster, and more controlled piston install every time.
Key Features & Benefits
- Precision Reverse Chamfer Design: Bottom chamfer aligns with the block’s bore chamfer to center the compressor perfectly and reduce the risk of ring damage during installation.
- Prevents Oil Ring Hang-Ups: Engineered to minimize the chance of the oil ring catching between the compressor and the block, improving assembly reliability.
- One-Piece Tapered Aluminum Construction: Durable and lightweight design ensures consistent compression of piston rings for smooth piston installation.
- Easy-to-Read Laser Etching: High-contrast laser markings on a black background remain visible even after repeated use in shop environments.
- Proven Performance Advantage: Tested against competing compressors and consistently delivers easier piston installation with fewer issues.
Key Fitments
- Bore Size Compatibility: Designed for engines with a 4.075" cylinder bore.
- Engine Applications: Commonly used in LS-based engine builds and other performance engines with matching bore size.
- Installation Use: Ideal for piston and ring installation during engine assembly or rebuilds.
