MRP 7a (aka 9age) Stroker Kit

After huge request we have designed a 7age/9age stroker kit (1900cc).
This is not your generic stroker kit with bad rod/stroke ratios or some random crankshaft with no thought put into the design. Huge amount of thought went into the design of this kit.
We are not a generic rod/crank supplier, we specialise in 4age performance and focus solely on making the best parts for your 4age.
Our kits are being used all around the world with power figures past 900hp on 45psi of boost! or in N/A form 250hp+ and 10,000rpm.

The pistons in this kit are a special custom design where we worked with CP to get what we needed.
Rod/stroke ratio is 1.52:1

Custom MRP 90mm Billet 4340 Crank based on the TRD/Atlantic Crank Design
Large counter weights to dampen harmonics at high RPM
Extra large section through rod journal to counter weight for increased strength and reduced flex in one of the most critical areas of load
8 Bolt to take 4age flywheels
OEM 4age journal sizes so you can use the OEM 4age size bearings
Oil gallery holes have lead in/outs to help increase oil flow to the bearings.
Oil gallery feeds are the same as the 4age crank meaning constant 360 degree of oil supply to the journals at all times unlike the 7afe crank.
Dual offset crank sprocket keyway
Nitrided, Fully balanced

Custom MRP Billet 4340 conrods with ARP 2000 bolts
Around 6% longer than the 7a rods
H-beam Heavy Duty
Rods are notched on the journals which acts as an oil squirter up into the bottom of the piston

Nitrided & Fully balanced
**Optional Saenz Conrods available for those seeking super high end rods. These are 20g lighter than our MRP rods – Saenz are one of the best in the world** +$900

Rings & gudgens supplied (80g N/A, 90g Turbo)
Special short skirt design to reduce friction which helps power wise & reliability
Ceramic coating on the domes to reduce heat to the pistons and keep the heat in the chamber (optional)
