springs, we could push the Walker
Evans-equipped car significantly
harder than our project machine. The
suspension stays up in the travel,
offering a much plusher ride. You feel
a lot less abrupt jarring through the
seat and wheel, and that allows you
to carry a lot more speed over rough
MORE SUSPENSION UPGRADES
Teixeira Tech builds some very
popular A-arms for cross-country
applications for both quads and UTVs.
Teixeira/CT started the project with
Teixeira’s XGC lower A-arms constructed with quality 4130 chromoly. They are TIG-welded in a preci-sion-built jig, making them basically
indestructible. The Ace has limited
ground clearance, so changing out
the arms makes a significant difference in how you can glide over rocks
and ruts. The Teixeira arms use the
stock ball joint, but Teixeira imports
significantly stronger Frap ball joints
from Italy. Frap ball joints press in
from the back side and then have
a clip retaining them. That way a
built-in shoulder accepts the load.
The stock ball joints press in from the
front side, and the retaining clip is
what holds them in position. Teixeira
Tech also builds an A-arm brace that
stiffens up the frame, and that was
slipped on. The brace doesn’t cost
much and adds a lot of strength.
PROTECTION & SAFETY
Teixeira built the Ace roll cage and
roof as well. The Teixeira cage looked
great, but we had an issue with it.
The cage was fine with the stock
seat, but when Teixeira/CT installed a
Pro Armor suspension seat, it lost too
much headroom, so learn from them.
Teixeira will build the cage taller on
request, or you can use a seat that
doesn’t hog so much room. Teixeira/
CT already had the G2 Pro Armor
seats from a RZR build and have
always liked them for comfort, so they
just threw one in. Pro Armor may
even offer a lower profile seat. Just
make sure you allow for headroom
on your build.
Teixeira/CT acquired some parts
from the Pure Polaris line. They went
with Polaris sport doors, and also
added lower door extensions. They
stuck on some of the sport door graph-
ics while working on it. Teixeira made
sure the cage fit those doors, and they
open and close very well. They also
grabbed up Pure Polaris’ low-profile
line of bumpers. They have a very
good price point and look great. The
front has mounts built in for attaching
lights. Teixeira powdercoated them
so they matched the roof and arms.
While clamping on some cool parts,
Walker Evans wanted to add some
horsepower via a Big Gun exhaust
system. Not only did the Big Gun EVO
U-series slip-on exhaust add horse-
power, it added a nice note—though
louder than we like. The Ace comes
delivered on the lean side to meet
emissions. Adding the exhaust mag-
nifies the issue and makes it too lean.
The Big Gun exhaust comes with a TFI
Power Box Fuel Management system.
Teixeira/CT slapped the machine on
CT Racing’s dyno just to check the
We like the compact light bar, and it is
nice that the Polaris bumper retains the
Polaris purposely made the Ace 570
narrow so it fits on quad trails. That
results in somewhat short suspension
travel. Walker Evans makes the most of
the available travel.
While we appreciated the added clearance from the tires, the taller tires raised the
final gearing and sapped some of the acceleration.
