SpeedFactory Racing JDM D15B SOHC VTEC Vitara Spec No-Notch Connecting Rods

Proudly introducing the new SpeedFactory Racing JDM D15B SOHC VTEC Vitara Spec No-Notch Connecting Rods!

Vitara piston turbo SOHC VTEC builds are one of the most popular 300-500hp street Honda setups out there. Very cost effective, fun, and relatively simple to build. One thing that has always been annoying though is having to use standard length off-the shelf rods that are unnecessarily large and heavy, and require the usual block and girdle notching to use. Time to kiss those days goodbye!

Introducing the ultimate rod for these setups – lightweight, strong, and clears both the sleeves & girdle for unrivaled ease of use.

Optimized specifically for Vitara JDM D15B SOHC VTEC builds, they offer high strength and quality at an affordable price. The custom rod length brings the Vitara pistons to the proper deck height and they are substantially lighter than other similar rods on the market.

The 2-piece forged 4340 chromoly construction provides outstanding strength and quality. Each rod is heat-treated, magnafluxed, CNC machined, and shot-peened to stress-relieve the metal. The rods have precision alignment dowels to positively locate the rod cap, maintain big end bore size, and eliminate cap walk. They feature bronze alloy pin bushings for floating wrist pins and come standard with 220,000 psi rated 3/8” ARP2000 rod bolts. Instructions and ARP Lube are included.
