In & Out Cackle-Safe Driveline Disconnect

PART NUMBER 13050
This device allows the driver to disconnect the output shaft from the driveshaft and safely run the car without having to hold in the clutch pedal. All normal driveline couplers stay engaged and do not rotate while the engine is running. The sliding coupler, output shaft, and driveshaft are made of heat-treated alloy steel, while the bearing retainer and fork assembly are machined from billet aluminum. The output shaft and driveshaft are custom made to the length required for your can depth and engine location. Due to the custom nature of this part, please call 1-866-508-6394 to order. $1,475.00

Aluminum Drive Plates for Floater Systems

PART NUMBER 55025 40 Spline, 5" x 5 B.C.
 
PART NUMBER 55026 40 Spline, 5-1/2" x 5 B.C.
This new Aluminum Drive Plate is designed for use with the Mark Williams Drag Race Floater systems. The unique design features an alloy steel spline insert permanently fastened in a 7075 aluminum alloy drive flange. This produces a weight savings of over 3-1/4" pounds when compared to the steel parts and reduces rotation inertia forces. The patent pending design is available for the 40 spline floater axles in the 5" x 5 and 5-1/2" x 5 bolt hole circle combinations. This part fits all series of MW floater kits with 11/16" drive studs. $300.00 each
 

7075 Aluminum Accu-BondTM Driveshafts

PART NUMBER 39890 4" 7075 Aluminum with 1480 Joints

Our 4” diameter 7075 Accu-BondTM driveshaft, with 1480 series universal joints is designed to withstand abuse of Pro-Modified racecars. It has 1480 billet 7075 end yokes that are bonded, (via our Patented Process) to priority 7075 tube. This strength breakthrough is 61% stronger than our previous best shafts. The 4” diameter is also beneficial for high RPM critical speed properties. 1480 series aircraft alloy steel transmission and differential yokes (both priced separately) are available for popular applications. $1,100.00


PART NUMBER 39555 3.5" 7075 Aluminum with 1350 Joints

This 3-1/2” Diameter 7075 Accu-BondTM driveshaft is designed for use in most high-horsepower door cars. It has 1350 forged end yokes made of 7075-T6 material connected with MW's patented bonding processes. This allows for increased ear strength, and allows for an approximate 50% weight reduction compared to a steel shaft, depending on length. Transmission yoke (sold separatey) is required for balancing. $815.00


PART NUMBER 39550 4" 7075 Aluminum with 1350 Joints

This 4” Diameter 7075 Accu-BondTM driveshaft is for high-horsepower cars that require the ultimate strength shaft utilizing 1350 series joints. The larger diameter increases the critical speed properties, often needed for longer shafts. It has 1350 forged end yokes constructed of high grade 7075 material. This material combination and bonding process creates a shaft that is 61% stronger than our previous best shafts. This allows an approximate 50% weight reduction compared to a steel shaft. Transmission yoke (sold separately) is required for balancing. $826.62


1480 Driveline Components

Transmission Yokes
Out Ultra Heavy Duty 1480 series trans yokes are 100% machined from heat treated billet 4140 chromoly. Similar to our 1350 series yokes, they feature an oversized 1480 U-joint that is 40% stronger than standard 1350 U-joints. These yokes are designed for high power applications where strength is more important than the assembly's weight.

PART NUMBER 39070 $304.00
16-Spline, Lenco & G-Force, D = 4-1/2"

PART NUMBER 39071$304.00
32-spline, Lenco, D = 4-1/2"


PART NUMBER 39074
$325.00
32-Spline, Liberty, D = 6-1/2"

Pinion Yokes
These pinion yokes are precision machined from billet 4140 steel. Just like the trans yokes, our 1480 series pinion yokes are 40% stronger than the standard 1350 series U-joints. Special fixturing ensures that every yoke runs concentric to the splines. For extra strength, a billet steel cap is required (purchased separately) rather than replace with standard straps.

Driveshaft Safety Loops

This device attaches directly to the differential third member eliminating tubular structures that attaches to the chassis. The front section loop is removable by four retaining bolts allowing easy drive shaft removal. The open design allows removal of the rear universal retaining bolts that are impossible to remove with enclosed tube designs. Constructed from 4130 material this satisfies the NHRA rule requirements for a "retainer loop 360 degrees of enclosure". Available for 9" Ford and MW 11" differentials.
