Thanks for the post. Someone else bought that truck, so I don't need parts. Someone else might need it.

Thanks for the info. Sadly the truck might be sold.

Air brake design FMVSS-121 covers air brakes, I believe. There are specific design requirements for enough air to capacity to provide x # of full brake applications and to replenish the air in a set time limit. You need a wet tank, dry tank and a tank for each axle all protected by check...

Transmission parts Are there any transmission parts? I would like to buy a m135 that has a bad trans. Can it be fixed?

Yeah, you're right, if you maintain consistent ride height where the angles are correct it should be ok. The vibration will only occur in bump positions. The extra lift increases the joint angles so having it right is more important. I just got an email from TMR. Their heim balls are 52100 high...

I see that the axle and pinion shaft changes pitch when the suspension moves up and down. This is caused by the upper links being shorter than the lowers. For a cardan joint shaft to deliver constant rotational velocity the shaft angles have to be equal at both ends and the joints yokes...

Thanks for the link gatos. Here, if the tare weight is over 12,000# the truck is commercial and subject to annual CVI including pulling all wheels and measuring the drums. Bobbing would get around that but you know the inspectors will be staring at you. I have seen truckers fined for having a...

Thanks; That looks like the ticket. None of the ends I have seen have scraper seals. Dirt would wear out the teflon in no time. Also most have unplated or cad plated balls which would rust in road use and wipe out the bearing. We have roadside dot inspectors who are just brutal nit pickers on...

I know ths is an old thread. Is this suspension road legal or a trailer queen? Would it pass a DOT inspection? How do you keep dirt from wearing out the unsealed heim ends? TMR Customs sells this as off road only. A truck like this is for sale and I am wondering if I would not be able to drive...
