For Sale

Lake Elsinore, CA


This Tube chassis was designed for 6100 or TT, SCORE series on down.

What I have for sale are the tubes for the roller chassis with some suspension tubes CNC cut and bent from 4130 material.

Included with the tubes are the cut files for the rest of the chassis, including the fixtures.

This file pack is normally sold for 15K, so you are basically getting all the chassis tubes for free 9K worth of value.

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.

Fullsize Trophy Truck – This platform is designed for Trophy Truck racing and is 125″ wheelbase by 94″ trackwidth.



Steering Setup – Designed for PSS steering racks, other options are available, please email [email protected] 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.



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.



Rear Suspension:

The rear suspension on the T4 is designed for 32” of wheel travel with lightweight components for a competitive assembly.

Rear End Assembly – The rear end housing is the T4 race housing, designed to be light and strong, setup for the 4 link in the T4 chassis with the bump stop mounts/sway bar mounts to match. It is designed to fit all Trophy Truck hub assemblies along with all 10” Race gear sets. If you choose to utilize a different rear end housing, you will need to let JEHC know so they can get you the proper link mounts to match the chassis.

Rear Link Arms - This lower link arm is a traditional Trophy Truck style with a 2″ main tube as the base structure and wrapped with a series of 4130 Chromoly platework. Setup for 3.0” coilovers and 4.5” bypass shocks.

Rear Sway Bar – The rear sway bar assembly is our T4 Sway bar that features a lightweight plate construction designed for a broached weld in sleeve. You can utilize a variety of different weld in broached sleeved for the sway bar or machine a custom one to match the sway bar you prefer.

Shocks – The rear shock package is setup for standard 16” stroke 3.0” coil overs and 18” stroke 4.5” bypass shocks with plenty of room for various tube layouts.

Rear Pivot Boxes – These are the Trophy Truck Rear Pivot Boxes from JEHC that feature mounting for 1” bearing lower link arm chassis pivots with ¾” bolts and upper 1.25” rod end link mounts with 5/8” bolts. Three mounting locations are provided so drivers can dial in the pinion movement/dive in the rear suspension they prefer.

Rear Fuel Cell – The rear cell is designed to be a simple construction that drops into place in the rear of the chassis, featuring 100+ gallon capacity you can choose how large you want the cell to be. A simple “X” bolts into place above the cell, holding it in.

Rear Spare Tire Setup – This chassis is designed for a simple spare tire strap setup that lays the spares down in the rear and utilizes either single or Y straps.
