Hi Guys I thought I would share some of my thoughts on the less expensive conrods on the market but particularly the MaXpeedingRods. Many of you will have seen them for sale in various online market places, eBay being one. However I do hesitate with these sellers as some can’t even get the name right calling them MaxSpeeding rods - there is no S in the name.
This makes me think that there may be copies out there - and when people take the time to copy MaXpeedingRods makes me think they are a worthwhile genuine product. Thus why not go to the companies own site and for the wet liner TR fraternity it is this one
MaXpeedingRods > Connecting Rod compatible for Triumph TR3 TR4 Conrod Con Rod Bielle ARP 2000 Bolts 800HP <
I have also found this discount code may be included that last for 2 years and it is “ ALou “ that’s worth 15% (that may be included in this link already ?)
I also know that some of you will have used them in your own rebuilds and for me that is in itself recommendation enough as you guys on this forum certainly know your stuff more than I.
I also understand that there is sometimes a wariness to use Chinese made products. To me this is not a Chinese issue it is a retailers specification issue. Typically poor parts are as a result of penny pinching poor specification. I don’t believe this is the case with MaXpeedingRods. But what’s the difference is between the H beam conrods that some of our specialist sell and the MaXpeedingRods ones that means that the specialist single conrod cost nearly as much as a whole set of 4 from MaXpeedingRods? I don’t know. It may well show itself in a full race 200BHP plus engine during a 40min full circuit race. But I am not in that league -
MaXpeedingRods seems to have made a lot of effort to state their specs like these rods linked to above say this :-
CR-TRIUMPH-158.75
TÜV Certification Con Rods
Type: Forged 4340 aircraft chrome moly quality steel for racing
H-beam Conrods Quantity: 4 Pieces a set
Bolts: Including Genuine ARP 2000 bolts
Note: Extra cost for upgrading to ARP L19 bolts
Bolts Size: ARP 2000 3/8" bolts
Tolerance: Balanced to +/- 1 gram in set
Piston Bolt Hole: +-4/1000mm
Power: 600hp ~ 800PS per set
Strength of the fastening (PSI): 220,000/230,000 PSI Torque: 48ft ≈ 65 NM
Top revs: 9000rpm
warranty: 2 years warranty for any manufacturing defect
- Forged SAE 4340 Chrome Moly Steel for the highest strength and durability, dedicated for Racing
- Designed and processed by CNC machine.
- All big and small ends are finished with SUNNEN honing machine
- Precision alignment sleeves positively locate the rod cap, maintaining big end bore size and eliminating cap walk
- 100% X-rayed, sonic tested and magnafluxed
- Multi-stage heat treated
- Shot peened to relieve stress
- Come with the bronzed bushing suitable for the floating piston pin
If you compare these to other well know makes and even mass manufacturers they compare very well, where these other suppliers actually state the specification!. The bold annotation is mine as the issues that I think are important when comparisons are made or quality needs a reasoning.
I have also looked at the matter of ARP bolts and I can only find confirmation that they are what they say they are. I am darn sure that if they weren’t ARP - ARP would be all over them with legal action or at least putting it out there if they were not legitimate as they have a considerable reputation to keep- as to the cost of the bolts as part of the whole conrod package I can only assume MaXpeedingRods have negotiated a great deal with ARP to the extent that MaXpeedingRods have their name on them as well as ARP now.
Here is the crunch - I am now planning a fast(er) road engine rebuild and I really like the look and the price of these MaXpeedingRods, yes they have gone up in price over the past year or so, but I see this as them becoming established in the market place. But when I asked for a free set they were happy to support my racing endeavours which is nice - but you may consider this a paid presentation, you may be right. All I can say is I was going to buy a set as others on here have done but I was cheeky and asked for a set- if you don’t ask you don’t get.
MaXpeedingRods conrods have been around for a while now and the company has diversified into turbos and suspension sets - (which seem to be going well in the world of modern cars) and as I am not keen on being a guinea pig I have let the market place decide. I can’t find any seriously negative comments. Those that have fitted them on this forum recently are probably still running in.
So I looked at the wider usage - they make them for what seems like hundreds of models of cars the vast majority are moderns
but our 6 cylinder cars are catered for too, as are the likes of the spitfire
> Search - triumph <
The moderns have the same material spec but their uses are far more extreme with high boost turbos and drift cars even British Touring car driver endorsements, Tom Chilton has been a brand ambassador. ( yes they may be paid for it but they are still putting their name to it) they are used in drifting cars and for me if they can last a season in these things they should be a life long partner in a TR , have a look at British drivers Dustin Miles and Oliver Evans and his 700HP car. A bit of a Lad !! but the car and driving is very impressive and a 2019 champion.

so what is next for me?? it is hopefully a spare engine being built to a fast(er) road spec with hopefully more power and more torque using the MaXpeedingRods , together with a warmer cam, 89mm pistons, probably webers and most likely going up a class in the club championship so watch this space.
