Sad day, but need to sell the Ultra4 in order to pursue other endeavors. This is a fast, light, low ultra4. Very competitive and easy to drive. Would be a heck of a fun single seat trail car as well. Only weighs 3700 pounds.

Chassis and suspension engineered and designed in Solidworks. Built in 2015. Ran LCQ at KOH and a handful of local races in CO and MI. Lots of test time. This is the first IFS/IRS Ultra4 built. Designed to be easy to work on, and easy to maintain. Many components are off the shelf.

Comes with lifetime engineering and technical support for the buyer. Any design changes you need, I'll be happy to engineer and help design.

As it sits, it has a detonated but built LM7, around 415 hp in the chassis. Have a freshened LM7 with valve springs and some head work to go with it. Front Differential is detonated. Locker is still good. Have new gears and housing for it.

Set up is mid/rear/side engine. 3 link trailing arm rear. a-arm front. It is designed to easily be converted to a solid rear axle if that is desired.


Does not come with:
Seat, belt, wheels, tires,

1.75" DOM chassis. Mixing in of 1.5 and 1.25. Tig Welded
Independent front suspension. A-arm. Custom knuckles. GM 1 ton 8x6.5 unit bearings. Corvette c3 calipers.
Independent rear suspension. 3 link trailing arm. GM 1 ton 8x6.5 unit bearings. Corvette c3 calipers

GM 9.25" Center sections.
RCV Pro4 CV's and Axles.
5.38 gears.
Eaton E lockers.
LS setup. GTO front sump oil pan. oil Accumulator.
Pro4 TH400 transmission built by ATD.
Dana 300 with Novak 32 spline super short output.

Swingset style steering with a steering box. Hydro Assist PSC.
Needs new pump and larger feed lines.
Steering quickener

FOA coil overs and bypasses all the way around.
20 gallon fuel cell with 4 internal flapper pickups.
Walbro 255 pump
Speartech engine harness

fresh air pumper
on board fire suppression (and it works! :))

A-arms - Lower
brand new set up rev2 front knuckles
spare 23 spline th400 output shaft
one spare diff housing
spare rear coil overs
Spare stock th400.

As it sits it needs a few things to be addressed to be ultra competitive (other than the diff replacement and engine swap) happy to discuss those with potential buyers via phone.

$32,000 as it sits. Again, it has pretty much everything coming with it that you need to go race it in February at KOH. (fresh engine, diff, etc. Add tires, wheels, seat, belts, and go race.)
Open to options including me swapping parts, etc, etc. Give me a call and let's talk about it.

Will.conaider partial trades. Built Jk, etc just ask.
