Manley Turbo Tuff Forged I Beam Connecting Rods Nissan Silvia 180sx 240SX S13 S14 SR20DE SR20DET.

We really like the Turbo Tuff I-Beam line from Manley. We have never been able to break one, even over the 1000whp mark, and they hold up well to extended abuse. They are probably the strongest rod for the money and we suggest them to anyone who wants to sleep well at night knowing they don't have to worry about their rods being a weak link in their high power build.

Our signature "Turbo Tuff" design combines the appropriate weight and rugged strength for ultimate horsepower applications. Each rod is shot peened after machining and magnafluxed. Bores are round and without taper. Bend and twist is tightly controlled. 
Cap fasteners are 3/8" APR 2000
