NEW & REVISED!!! ARP has released a new version of their race-grade M3 connecting rod bolts and its better than ever before. If you're replacing your rod bearings these rod bolts are far superior to standard the OE BMW fasteners in terms of durability and ability to withstand stresses. This set of rod bolts is made specifically for the S65 4.0 liter V8, as found in the 2008-2013 M3 and replaces the previous ARP kit part number RBK_S65.

ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated, ensuring complete heat penetration, to increase the clamping load up to 200,000 psi. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best head studs we've found and we highly recommend them in both racing and forced induction applications. Due to the additional clamping force between the head and block, these are IDEAL for turbocharged engines.

JE Pistons are a popular aftermarket upgrade for the S65 engine. JE Pistons specialize in high-performance forged pistons designed to withstand the extreme demands of motorsport and performance builds. When used in the S65, they offer the following benefits: Increased Strength: Forged from aerospace-grade aluminum alloys, JE pistons are much stronger than cast pistons, capable of handling higher compression and power levels. Lightweight Design: They reduce reciprocating mass, improving throttle response and engine revving characteristics. Customizable Compression Ratios: JE Pistons can be tailored to specific performance goals, such as higher compression for naturally aspirated builds or lower compression for turbo or supercharged applications. Improved Durability: JE's pistons are designed to handle high heat and stress, making them ideal for high-revving engines like the S65.
