McLeod Ford 96-98 Cobra/96-00 Mustang GT V8 Street Extreme 10.5 X 1-1/16 X 26 Spline Clutch Kit

The McLeod 75307 Street Extreme is a 10.5-inch performance clutch kit for SN95 and Fox-era V8 Mustangs that have been converted to an aftermarket 26-spline transmission, such as a TKO or T56 swap. Our listing title covers the 1996-98 SVT Cobra and 1996-2000 Mustang GT; McLeod's own catalog lists it more broadly for 1986 through April 2001 GT and 1993-98 Cobra cars. If your built 4.6 or 5.0 is slipping the stock clutch in third and fourth, or you are finishing a five or six speed swap, this is the kit built for that input shaft.

What the Street Extreme kit does

The Street Extreme pairs a high-clamp-load diaphragm pressure plate with a dual-faced ceramic, sprung-hub disc. Extra clamp load and ceramic friction give much more holding power than an organic stock replacement while keeping the pedal manageable for daily driving. McLeod's current page rates the Street Extreme family at up to 600 hp depending on part number, and older McLeod catalog copy quotes up to 700 crank hp and torque with moderate mods on street tires. The kit is SFI approved and includes the pressure plate, disc, throwout bearing and pilot bushing where applicable, and an alignment tool.

Symptoms this kit fixes

• RPM flares without acceleration on a hard 2-3 or 3-4 shift after adding power
• A stock or light-duty clutch that glazes on the first track day
• Chatter and smell from a worn disc on a car that already has a TKO or T56
• Pedal engagement creeping higher as the old disc wears thin

Expect a ceramic disc to engage more quickly than organic. A little takeoff chatter when cold is normal for this facing material.

Confirm the spline before ordering

This is the most important check on this page. The input shaft spline count decides the kit, and the listing title reads 1-1/16 x 26 while McLeod's catalog line for 75307 reads 10.5 x 1-1/8 x 26 spline, aftermarket transmission. Count the input shaft splines on your gearbox. A factory 10-spline car needs the McLeod 75305 Street Extreme 10-spline kit instead.

Fitment

Listing fitment: 1996-98 Mustang SVT Cobra and 1996-2000 Mustang GT V8 with a 26-spline input. McLeod catalog: 1986 to April 2001 GT and 1993-98 Cobra with an aftermarket 26-spline transmission. The 10.5-inch cover needs a flywheel drilled for the 10.5-inch Mustang pattern. On 1996-98 modular cars that is usually a 6-bolt crank, served by the McLeod 563406 aluminum flywheel; Windsor 8-bolt 4.6 engines use the McLeod 563408. Both are multi-drilled for the 10.5 and 11 inch patterns. Send your year, VIN and transmission model if you want us to confirm before shipping.

Install notes

• Resurface the flywheel or install a new one; a ceramic disc on a glazed surface will chatter.
• Use the supplied alignment tool and torque the pressure plate bolts gradually in a star pattern.
• Install the new pilot bushing and confirm release bearing geometry for your swap. Cable cars converting to hydraulics can use the McLeod hydraulic release bearing kit for 1979-04 Mustang.
• Bleed the hydraulics and set pedal free play before driving.
• Follow a gentle break-in before launches; see how to break in a new clutch.

Will the 75307 fit my stock 10-spline Mustang transmission?

No. It is a 26-spline kit that McLeod catalogs for aftermarket transmissions. A factory 10-spline car needs the McLeod 75305 Street Extreme 10-spline kit.

Is the spline 1-1/16 or 1-1/8 inch?

The listing title says 1-1/16 x 26, but McLeod's catalog line for 75307 reads 1-1/8 x 26 spline. Count and measure your input shaft and match it before installing.

How much power does the Street Extreme hold?

McLeod rates the Street Extreme line at up to 600 hp depending on part number, and older McLeod copy quotes up to 700 crank hp and torque with moderate mods on street tires.

What comes in the box?

High clamp load pressure plate, ceramic sprung-hub disc, throwout bearing and pilot bushing where applicable, and an alignment tool. A flywheel is not included.

Which flywheel should I use with it?

Any flywheel drilled for the 10.5-inch Mustang pattern that matches your crank. McLeod 563406 (6-bolt) and 563408 (8-bolt) are multi-drilled for 10.5 and 11 inch covers.
