MRE Rotators & Part Combos

MRE is now offering parts and complete rotating assemblies to sell. These are the same parts we use in our own engines. We buy the products at a high volume so you will notice we have good prices for these items.

 

 

Mullins Custom Callies Crank

  Available in 3.625 3.750 3.875 4.000 strokes. All cranks have 2.0 pin on 3.750 and larger strokes (this allows more rod to cam and block clearance). These cranks are custom ground to our specs. We have been using this style crank in all of our own motors for the past four years.
 

$1,745

  We are going to start carrying Honda journal size in the 3.875 stroke option only.
 
carrillo-rods-tn  

Carrillo Bullet Rods

  MRE solely uses Carrillo rods on all our Stage 2-3 Modified engines. This includes all 13 and 23 degree combinations. This rod has been phenomenal on reliability. The bolt quality is second to none; they do not require replacement on rebuilds. This alone saves the customer $225 on a freshen bill. We offer them in six inch, with 2.1, 2.0, and Honda journals. We will soon be stocking them with a .866 pin, .927 is standard. The 2.0 is our most common and it weighs approximately 620 gms. This is the rod that comes standard in our Stage 2 Rotating Assembly.
 

$1,145

 
carrillo-rods-ltmod-tn  

Carrillo Rods

 

This is the highest level of rod we offer. We mainly use this in our Late Model engines but sometimes a customer will want this upgrade. In Modified racing we don't feel like this rod is needed.

 

$1,695

 
 

CP Custom Pistons and Ringsets

  Custom designed by MRE for our Outlaw Cylinder Heads and motor packages. Available bore sizes 4.125 - 4.155 in .005 increments to accommodate all of our stroke combinations.
 

Pistons $850
Rings
$195

 
Now you can use the same parts we are using on our bottom ends. You can buy individual parts or custom build your own rotating assembly. We will also offer a balancing service so when your parts are delivered they are ready for assembly
