T4 Trophy Truck/6100/7200/Aussie Spec Front Clip

 

The T4 Chassis Front Clip Platform is Available in several different configurations including Trophy/Trick Truck, 6100, 7200, and Aussie Spec class. Below are all the specifications for the Trophy Truck/6100 class platforms, the other platforms are dialed down versions of this setup. For questions or inquiries please contact [email protected]

This Front Clip is everything you need to graft the T4 front end to an existing chassis or build a chassis off of it. Included in this digital asset pack are all the tubes in GREY, the main tubes with shock / bump stop mounts setup for the T4 front suspension.

The front suspension of the T4 is designed to be light and strong, precision design for a competitive race platform. Utilizing tube in the components to increase strength and reduce weight while providing a unique style.

Bulkhead – Plate and Tube construction with various thicknesses (1/4”, 3/16”, 1/8”, and .095”) and uses sheetmetal weld washers (can replace with KARTEK machined weld washers) for all bolt hole locations. Setup for the Howe Trophy Truck Rack this bulkhead is self-locating (snap together).  

            Lower Arm – Uses 1” uni-ball bearing chassis pivots and 1.5” uni-ball bearings for the upright side.

            Upper Arm – Uses 7/8” Rod ends with Standard Square receivers (bungs) from Kartek with the same 1.5” bearing for the upright as the lower arm.

            Upright – Uses custom machined snout block for 12 bolt bolt on hub setups with custom machined upper arm mount pin and lower arm threaded bung setup for ¾” bolts and 9/16” for the steering 1” rod end.

 

Trackwidth – With standard race 2.5” hubs and wheel/tires this setup is about 92.5” outside tire to outside tire. Narrower setups are possible with different hubs and higher offset wheels.

 

Shocks / Wheel Travel – This setup is designed to run 14” stroke shocks side by side. Wheel travel is optimized at 24” usable, 25” metal to metal.

 

Steering Setup – Designed for HOWE TT steering racks, other options are available, please email Jason@tekkconsuilting with any questions.

 

Hubs and Brakes – This platform utilizes standard 12 bolt faceplates for a variety of bolt on hub options from standard 2.5” up to TT assemblies. The standard Race 2.5” hub and race wheels/tires brings the overall trackwidth to about 92.5” outside tire to outside tire.

 

Tires and Wheels – Depends on the hub setup you utilize but the uprights are optimized for 39-42 tires, 37” will work but that is the lowest tire size we suggest running on this front end.

 

Bulkhead Rake – This front end is designed for a bulkhead rake of 3 degrees with 4-5 degrees of caster built into upright/arms for a total of 7-8 degrees of caster. The lower and upper arms are parallel

 

Camber Curve – At Compression (Bump) this setup gains about 7 degrees of camber and at Extension (Droop) the setup stays decently straight with only about 2 degree of change.

 

Contact Patch Trackwidth Change – Imagine the CenterPoint of the tire where it touched the ground, this point is the contact patch of the tire. When the suspension moves up and down this width changes (opposite of the camber curve, larger camber curve = less contact patch trackwidth change). At Compression (Bump) this setup decreases 1” in trackwidth and during Extension (Droop) is 4.5” of decrease.

 

Bumpsteer – Designed around the Howe Trophy Truck rack the bumpsteer is extremely minimal, unfortunately there is no such thing as “zero bump steer”, no matter what you do its physically impossible to eliminate bump steer. Even though the bumpsteer is next to nothing in CAD, with tolerance stacking during fabrication you will most likely end up with a few millimeters of bumpsteer.
