1. Which vehicles and engines do these connecting rods fit?
They are listed for BMW M3 E36 and E46 models with the S54B32 6-cylinder (European model). Verify fitment against your engine block/crank dimensions and part number before purchase, as non-European S54 variants can have differences.
2. What material and rod design are used?
Forged SAE 4340 chrome-moly aircraft-quality steel in an H-beam design, manufactured and finished for racing use.
3. What quality control and finishing processes are performed?
All rods are CNC machined, big and small ends finished on a SUNNEN honing machine, 100% X‑rayed, sonic tested and magnafluxed, multi-stage heat treated and shot peened to relieve stress.
4. How many rods are included and are they balanced?
The set includes 6 connecting rods and they are balanced as a set to +/-1 gram.
5. What fasteners are supplied with the rods?
Genuine 3/8" ARP 2000 bolts are included with the set. An upgrade to ARP L19 bolts is available for an extra cost.
6. Are these rods rated for 800HP as the title states?
The product listing indicates suitability up to 800HP. They are forged 4340 racing rods and engineered for high-power applications, but final capability depends on your build (boost, RPM, supporting components). Consult your engine builder for confirmation.
7. Do these rods support floating piston pins?
Yes. The rods come with bronzed bushings suitable for use with a floating piston pin configuration.
8. What are the key dimensions of the rods?
Center-to-center length: 139 mm. Big end inner diameter: 53 mm. Small end inner diameter: 21 mm. Big-end and small-end widths are not specified in the listing—contact the seller if you need those exact widths.
9. Are these OEM rods or aftermarket, and do they have certifications?
These are aftermarket forged rods (not OEM). The listing states the rods have TUV certification and emphasizes higher-quality 4340 steel construction compared to low-quality alternatives.
10. Is professional installation required?
Yes. Proper installation requires new bearings, correct bolt torque/stretch procedures, verification of big-end clearances, rod-bearing crush, piston-to-wall clearance, and final dynamic balancing. Have a competent machine shop or engine builder perform or check the installation.
11. What torque or installation specs should I use for the ARP bolts?
Follow the ARP torque or angle specifications for the specific bolt (ARP 2000 or L19). ARP provides detailed installation and torque/stage/bolt-stretch procedures—use their documentation or consult your machine shop rather than guessing torque values.
12. Is there a warranty?
The listing states a 2-year warranty. Confirm warranty terms, coverage, and any registration requirements with the seller before purchase.
13. Will these rods require additional clearance for stroker cranks or aftermarket pistons?
Possibly. Because big-end width and small-end widths are not specified, and aftermarket cranks/pistons can change clearances, you should verify clearances for your specific crank and pistons. A machine shop can check and modify clearances if necessary.
14. How can I confirm these rods will work with my engine?
Compare the rod center-to-center length, big and small end diameters, and bolt hole pattern to your stock rods and crank journal sizes. If unsure, provide your VIN/engine details to the seller or consult an engine builder to confirm compatibility.
