Performance T-Case Build Service - EVO X
This is the ultimate EVO X T-Case! This Performance Build Service is different over our standard build service in that it includes: gear treatments, modifications to the ACD clutch assembly, and additional tweaks to make this T-Case as strong as possible.
Designed for street and track use!This Build Service Includes:
- Ring and Pinion Gear Set - Treated (Custom Made for Jacks Trans)
- Seals and O-Rings (excludes ACD Piston Seals)
- Pinion Bearings
- Tighter Bearing Preloads (Prevents Gear Breakage and Wear)
- Modified ACD Clutches (15 of them) to give you more center diff LSD action
- Pressure Testing ACD Assembly (checks to ensure piston seals are healthy and fluids do not mix)
- Fill / Drain Plug Washers
- Complete tear down and cleaning using our state of the art equipment found HERE
We modify the pinion bearings to sit tighter and machine them to fit perfectly inside the housings without the use of the pinion shims. The pinion gear shims are not accurate enough for the tolerances we set your ring and pinion to in this build! During high powered and shock loading applications, the shims can compress which will change the bearing preloads and gear contact. With no shims around the pinion gear, that is no longer possible.
Please note that if your T-Case is making whining noises, THIS BUILD SERVICE WILL CURE THAT PROBLEM!
This transfer case has been used in multiple cars with over 800HP.
Have a rally car which breaks T-Cases every time you are air-born and slam the ground at wide-open-throttle? We have the Pikes Peak Hill Climb right here in our back yard and know what it takes to make a transfer case live under extreme conditions! We always watch people from out-of-state break their T-Cases built by a competitor. They rarely realize that an indestructible T-Case option is right here at Jacks Transmissions which will dominate the mountain. The truth is -- Having a cheap T-Case break due to a sponsorship is not worth it when it makes you lose the race.
With the best cleaning equipment, we also have a very clean facility. All units are built in a spotless environment and using tools, and benches, which are clean and only used for assembly purposes. In other words, the same tools used to pull your dirty old t-case out of your car are NOT the same tools used to rebuild your pristine unit afterward. Take a look at the typical shop and check their tools. It is shocking how dirty things are in most shops and that dirt will end up in your unit. That doesn't happen here.
Your unit is also shipped in a double walled custom made box for Jacks Transmissions. Your unit will be sitting snugly, and safely, in preformed foam pads to assure a trouble free delivery.
Note: Core charges will be refunded -- depending on the condition of your core!!
CORE RETURNS MUST BE RECEIVED WITHIN 60 DAYS FROM THE ORIGINAL ORDER DATE
