Cat XLS vs Procat

[DanB4]

Hi guys,

What are the main differences between the XLS and the Procat?

Is it possible to back-convert a Procat to make an XLS and will an XLS replica shell fit the Procat?

Thanks,

Dan

From memory the biggest differences were the chassis and the rear suspension.
If you just swapped the chassis then the xls shell should fit

Yep, just change the bottom chassis plate and jobs a good'un

Excellent thanks guys

I guess Fibrelyte is my only option for a CAT XLS chassis plate? Then I'll need a rear wing mount, wheels and front bumper too....that all?

The rear suspension is completely different between the XLS and Procat. Also the rear shock tower, XLS has chrome rims, even the front uprights were different. If you want to build a car that will kinds replicate the XLS it's no big deal but if you want to pass a Procat off as an XLS well thats an entitrely different thing.

My XLS-





Procat

If you want something that looks like an XLS at a glance then the XLS chassis will allow you to fit the body on. Add some black 2" wheels and the less informed will be none the wiser as they won't notice the wire wing mount and front bumper.

But anyone with any knowledge of the old Cats will easily tell at a glance that it isn't an XLS by the rear suspension and shock mount. If anyone asks which vintage Cat a car is, the first thing you look at is the rear upper arms. Changing the bumper and wing mount won't make much of a difference. Fitting an XLS bumper also means you can't easily get at the Procat belt tension screws either unless you drill a pair of holes in it.

Full list of differences as far as I can remember.
Front bumper
Front gearbox casing, Procat has tensioning screws
XLS has an 8 ball front diff pulley, Procat has a 14 ball front diff pulley
Different chassis plates
XLS has rear diff in spur gear and integrator in rear, Procat has solid layshaft and diff in rear
XLS rear suspension parts are the same as the front suspension. Upper suspension mount brace is fibreglass, shock mount is fibreglass and wire wing mount
Procat rear suspension is taken from the Cougar with adjustable upper link instead of double wishbone. Upper link mount is similar shape to XLS brace, but in moulded plastic. Moulded plastic shock and wing mount.

The only major parts shared between the two are the rear gearbox case, upper deck, driveshafts and the whole front suspension.
