 We are now offering the option of shot peening as one of the services that you can get done to any of the parts that we sell.  Shot peening is a cold metal working post process which is done to the gears to make them tougher and last longer. As the shot strikes the gear it peens the surface, leaving  small indentations or dimples. Overlapping dimples develop an even layer of metal in residual compressive stress. This is a good thing for it is well known that cracks will not initiate or propagate in a compressively stressed zone, such as the root radius of the gear teeth.  Rule of thumb: shot peened gears generally act like they are 20% larger in cross section and will hold up to high torque much better than gears that aren't shot peened.

Reverse Synchro, all years =  $30.

TRE also has the custom double synchro gearsets for 1st through 5th.  Ask for pricing.

Is your clutch adjusted properly?

1ST GEAR & INPUT SHAFT  

GEAR RATIO = 3.083 (STOCK)

When rebuilding your transmission always inspect the input shaft for damage or excessive wear of both the gear teeth and/or the splined sections of the shaft.

Includes: OEM input shaft and 1st gear.

$245. w/ gear machined for single synchro option. (synchro included)

$285. w/ gear machined for double synchro option. (synchro not included)

DOUBLE SYNCHRO 2ND GEAR KIT

GEAR RATIO = 1.684 (STOCK)

The double synchro 2nd gear will allow you to upshift into 2nd gear at much higher rpms/vehicle speeds. How high? a bazillion rpms, that's how high.  We've tested it above 10,500 but you should be more concerned about having a properly adjusted clutch.

$315. Includes: modified 2nd gear, 1st/2nd hub & slider, 1st & 2nd gear synchros, keys and springs, the end taper roller bearing and snap ring.

Add $10 for shot peened gearset.

Inspect your hub for wear; there should be no signs of seizing or abnormal wear. Check the engagement teeth for damage & wear. If the transmission crunches while shifting into 1st or 2nd you will most likely need this part and the synchros.

The center differential performs the strenuous task of sending power to both front & rear differentials. Speed Design's 4 spider center differential with Torrington thrust bearing has proven itself capable of hold up to the abuse of hard launches and parking lot mischief better than those that are using a cut-down stock cross shaft. We precisely CNC machine the center differential housing leaving more material in critical areas which allows the housing to retain the more strength. The cross shaft, by design, has twice the load bearing surface when compared to using a cut-down OEM cross shaft.  Some will try to save money by machining down the factory cross shaft. However, this is not nearly as strong and from the material science side because you have the problem of the two extra spider gears rubbing on a surface that doesn't have the correct hardness to avoid galling and wearing out prematurely.  The Speed Design cross shaft is made of a high strength alloy and is precision ground after heat treat, the correct way to do it.  If you're always leaving the line hard Speed Design's 4 spider center differential is recommended and we feel that it is the best 4 spider center diff out there, period.

Includes: Torrington bearing upgrade, new shims and spider gear washers.

$550. requires your center diff to be sent in & machined.

$950. new, outright, without a core needing to be sent in.

Do-it-yourself special  Send your center differential housing to be machined out for the 4 spider conversion. $100.

Add $30 for shot peened spider gearset & detailed & shot peened outer differential gear.

TRE recommends using your existing center differential, if the outer gear isn't damaged, because the teeth have been bedded together with the intermediate gear in your transmission.

POORMANS cheap 4 spider center diff.  This is for those who  want a Delmonico steak but can only afford a hotdog.  Sarcasm aside, this is the next best thing  to the Speed Design 4 spider center differential that we sell.  A new factory OEM cross shaft is precision ground to the proper tolerances and the center differential housing is CNC machined to allow for the 2 extra spider gears. It's the best low budget 4 spider out because the machine work is the best.   If I were you I'd option for the Speed Design 4 spider center differential.  Why? Because it's worth every penny in the long run.

Includes: Torrington bearing upgrade, new shims and spider gear washers.

RIPGRIP FRONT DIFFERENTIAL

What is a RIPGRIP?  It's the infamous limit slip insert thingy for your transmission's open-style front differential, designed to provide increased traction to both front wheels.  CNC'd from tool steel and it has the strongest springs available so you get the most lock-up possible. You will not break this thing! We stock them for the the FWD & AWD Mitsubishi vehicles and custom units are available upon request.

NOTE:  It is recommended that you send your differential to our facility for the installation service (listed above). We are now machining the contact surfaces of the spider gears so that they are matched to the surface of the RIPGRIP and modifying the differential housing to provide more lubrication to the surfaces that wear out.  This provides a substantial increase in the limited slip action while providing a longer service.

 $85. RIPGRIP.

5 year warranty

Hands down this is the best limited slip you can use in your AWD.  It features a full lifetime warranty, even when used for racing.  This one takes a beating and keeps on working day after day.  Drivability is excellent, it's quiet and doesn't break! We highly recommend the Quaife.

$1250. Quaife ATB, Automatic Torque Biasing front differential.

TRE offers a center differential spool for the AWD DSM gearboxes. This allows the power to be sent equally to both the front and rear differentials, improving traction, by replacing the stock side & spider gears, that are inside your center differential, with a spool. The name "spool" is old drag racing slang for the drive wheels being "locked" together so that they both turn the same speed regardless of traction, wheel size etc. but in the case of the center diff the spool locks both the front and rear portions of the AWD drivetrain together.

Drag racers like the spool because it reduces their 60' times by as much as .2ths of a second.  Rally guys like it because it reduces understeer while cornering.

The high quality spool is CNC'd from a one piece billet and allows the front pinion shaft and output shaft to "float" keeping unnecessary stress at the splines to a minimum.  The increased spline lengths better distribute the load onto the pinion shaft & output shaft. The end result is that front pinion shaft or side gear failure is virtually eliminated. The viscous coupling is replaced with a clever billet Aluminum output shaft retainer included.  The spool and revised jamb pads are heat treated for ultimate durability. 

The new jamb pads no longer require the retaining bolts, eliminating the problem of the bolts backing out.  This easily installs into the center diff without any modification or welding and can be removed and reused in any AWD transmission 89-99.

$235. Includes: Spool, revised jamb pads & retainer.

TRE recommends using your existing center differential, if the outer gear isn't damaged, because the teeth have been bedded together with the other gear in your transmission.

$45. Welding of center differential.

How does it drive?  Like a 4 wheel drive "locked". You'll notice it when turning into Taco Bell or when coasting into a parking spot.  Great for rally or drag.

This kit includes all the bearings for your transmission.

$240.  Includes: Full bearing kit.

Viscous Coupling Eliminator

 Installation is less than an hour with simple hand tools.  The VCE can easily be removed and used over and over again.  Perfect for the dyno owner and those with an AWD or those who want to lock the center diff.

$85. VCE

Now this is a wise investment.  Flywheel explosions are known to destroy the vehicle and injure the driver or anyone in harms way.  Most drag strips require scatter shields if you're running 12.99 or quicker.  These scatter shield are built from .250" thick stainless steel, have four mounting points and fit the 89-99 DSMs both FWD & AWD.   Protect yourself and your investment. 

$195. Stainless steel scatter shield.
