ARP Rod Bolts BMW E30 M3

The ARP S14 Rod Bolt Kit is part of the ARP Pro Series of premium-quality products. These connecting rod bolts are precision CNC-machined to ARP's exacting specifications and designed for optimum reliability for your E30 M3 S14 engine. This rod bolt set can be used on all S14 powered E30 M3, including model years 1987, 1988, 1989, 1990 and 1991, with both stock 2.3 liter and stroked 2.5 liter engine variants. ARP S14 rod bolts are thread rolled after heat treating, which gives them about 1000% (that's ten times!) better fatigue strength than those studs that are threaded prior to heat treatment (a very common industry practice). It costs more to do it this way, because it's tough on tooling, but the results are well worth the extra effort. ARP Pro Series rod bolts are far superior to standard OEM fasteners in terms of durability, and they're fully capable of handling the extra stress of high-combustion engines.
