1. Which Triumph models and years do these connecting rods fit?
These are specified for Triumph TR5, TR250, GT6 and late-model TR6 engines. They are listed as 'late model' TR6—verify your engine variant before purchase.
2. How many connecting rods and bolts are included in the package?
The set includes 6 brand-new H‑beam connecting rods and 12 genuine 5/16" ARP 2000 bolts (enough bolts for 6 rods).
3. What are the key dimensions of these rods?
Center-to-center length: 146.05 mm; Big end (crank) diameter: 51.34 mm; Small end (wrist pin) diameter: 20.63 mm. Big-end width and small-end width are not specified in the listing—measure or confirm with the seller if required.
4. What material are the rods made from?
They are forged from 4340 (EN24) chrome-moly aircraft-quality steel and produced in an H‑beam design for strength and durability.
5. Are the rods balanced?
Yes — the set is balanced to within +/- 1 gram between rods in the set.
6. Do these rods come with ARP bolts, and can I upgrade the bolts?
The kit includes 12 genuine ARP 2000 5/16" bolts. An upgrade to ARP L19 bolts is available for an extra cost—contact the seller for pricing and availability.
7. Is professional installation or machining required?
Professional installation by an experienced engine builder is strongly recommended. Depending on your engine condition and clearances you may need bearing sizing, align-boring, or additional machining; always verify clearances and follow best practices for rotating assembly assembly.
8. What torque or installation procedure should I use for the ARP bolts?
Follow ARP's published torque and assembly procedure for the specific bolt material (ARP 2000 or L19) and fastener size, including proper thread cleaning, lubrication, and recommended torque or stretch method. If unsure, have a qualified engine builder perform the installation.
9. Can these rods be used for high-performance or racing builds?
The forged 4340 H‑beam design is suitable for performance applications, but final suitability depends on your engine's power levels and build. For very high horsepower or aggressive applications, consider upgrading to ARP L19 bolts and consult an engine builder.
10. What is the warranty on these connecting rods?
The product carries a 2-year warranty. For warranty claims, contact the seller or manufacturer with proof of purchase and details of the defect.
11. Are the small end bores bushed or do they require separate wrist pin bushings?
The listing specifies the small end diameter (20.63 mm) but does not state whether bushings are installed. Confirm wrist-pin/bushing requirements with the seller or your engine builder to ensure compatibility with your pistons and pins.
12. Will these rods work with stock Triumph bearings and crankshaft?
The big end diameter is listed as 51.34 mm, but compatibility with stock bearings/crank journals should be verified. Have an engine builder check clearances and bearing sizes before assembly.
13. Are the rods delivered pre-assembled with caps and bolts torqued?
The kit includes rods, caps and bolts, but final assembly, proper torqueing and checking of clearances must be performed during engine assembly—do not assume they are pre-torqued for final use.
14. What does 'balanced to +/- 1 gram in set' mean for my build?
It means each rod in the six-piece set is matched by mass so the weights differ by no more than one gram—this helps reduce vibration and simplifies balancing the complete rotating assembly, but final dynamic/static balancing should still be performed with pistons, pins and crank.
15. How can I get more technical details or dimensional drawings?
If you need additional dimensions (e.g., big-end width, small-end width) or technical drawings, contact the seller or manufacturer directly before purchasing so you can confirm fitment and clearances.
