The XR311 was Tamiya’s first off-road vehicle and it’s first kit with a fully independent suspension.
Back in the 70′s, the U.S. Army was looking to replace its aging jeep fleet with something more modern. The XR311 was one of the vehicles being considered. Ultimately, the Humvee won out, but not before Tamiya released an R/C kit. Above is the re-issue released in 2001. It is very faithful to the original design right down to it’s all metal chassis and hard styrene plastic body.
The first thing I did when assembling the XR311, was to replace the bronze bushings with ball bearings.
These are the front steering assemblies going together.
Full front suspension ready for mounting to the chassis.
Rear suspension and axle pieces. The XR311′s suspension is fully independent in the front and rear.
Rear transaxle assembly and housing. No differential in the XR311.
Rear axle housing, rear suspension, and motor come together.
Front suspension assembly ready to be mounted to chassis.
Front and rear suspension mounted to chassis.
Tires are scale in design and include a nice scale three piece wheel design.
Fully completed rolling chassis.
Painted and ready to roll!

hello nice xr311, i`ve just bought the cheetah of e-bay and i was wondering if you know where i can get the rivised torsion suspension of the zr311 from ? if it will fit.
thanks robert.
Where to find the suspension is a tough question to answer because it’s not something that sold as a package. You’d probably have to piece it together from parts. Unfortunately, I don’t have a Cheetah to do a direct comparison of suspension parts. It seems that the only weak link in the Cheetah suspension is the plastic torsion bars. How about seeing if you can pick up some XR311 metal ones from Tamiya?
Hello thank you for your reply, luckly the ones i got on mine are not broken yet i was looking more into the future when they do. I shell give tamiya a try and see if the car or parts are still listed.
thank you Robert.
Can you please help i am looking for some spare tyres for my tamiya xr 311
Thanks mike
Try calling Tamiya to see if they have any in stock for the re-re’s. If not, ebay is your best bet. You can also try the uber Tamiya fan site, Tamiyaclub.com and post a WANTED ad. Come to think of it, you can also post a wanted ad on ebay.
Hi!
Great looking xr311. What colour did you use to spray it? It looks great. I’m ‘doing’ one at the moment.
Keep up the good work with the site. I love reading it at work!
Cheers, Alan
Thanks, I used Testors Olive Drab. Glad you enjoy the site!
Nice site and nice car!
Bought one of these yesterday, a re-re car, and plan to put in ball bearings. You dont happen to remember the sizes and numbers of bearings used? Tried to disassemble the car last night but didnt come too far…
best regards
Martin
I don’t recall all of the bearing sizes, but the manual should list all of the bushing sizes, which would be the same dimensions for the replacement bearings. I believe I bought my bearings as a “package deal” off of a seller on ebay who packaged up different bearings collections for specific Tamiya cars. I just did a search for “xr311 bearings” and didn’t find any listings, but I saw listings for Sand Scorcher bearings. Maybe contact one of these sellers and see if they can package up an XR311 collection for you.
