Jayson – Not sure…but I bet Low Range can explain it to you.

I decided to buy The LROR and I’m glad I did. Impressed with the quality and it makes the Truck look way better. I installed myself, then took to a local shop to get alignment done. They told me that they were unable to get caster back within spec. I called LROR and they said that they hear that all the time from random shops but they said that the dealership shops never have any problem getting them in spec. My dealership is 160 mi away. Is there anything that the dealership knows about aligning the tundra that my local shop doesn’t know? Perhaps some unusual adjustment on the upper control arm that isn’t obvious?
Thanks

BC – Spring pre-load. The additional length on the strut assembly results in some pre-load on the spring, reducing the amount of spring compression at rest. SO, you get 1.5″ from the spacer and 1.5″ from the reduction in “springyness.” Make sense?

Hello. I just received this kit and I agree with everyone else that this is a great looking high quality kit. I plan to have it installed next week and an alignment performed at a local dealer. I only have one question and it could be a stupid one. It appears to me that the front strut spacer is only about 1.6 inch tall (overall height). Did I receive the wrong spacers? I’m not sure how you get a 3 inch lift from a spacer that is not 3 inches in height.

DJ – I hear ya. I don’t think you’re saying that this design is bad, more so that it’s inherently susceptible to corrosion. I think the issue is very much dependent upon conditions and maintenance. If a vehicle owner in the N.E. is careful to regularly wash a vehicles undercarriage (with special attention paid to the aluminum spacer), that might be enough to avoid any negative consequences. Still, it’s a great point – aluminum isn’t the ‘perfect’ material…but it’s close!

In my experience, mind you the equipment I worked with was constantly wet with either salt or fresh water, anodizide parts worked great with the non-metal contact with the aluminum part. But the areas of contact the pitting, desolving, and honeycombing was even worse. I had used anodes (zinc) which did slow the process down, but clearly did not solve the problem. I have even built a dc voltage regulator to ground the equipment, but this interfered with the computers on the equipment (and the ship, as it showed up as a ground onboard, a big no-no with the ships electronic equipment. The companies policy on electrolysis of its equipment was then normal wear and tear, even if the part failed in 6 months. This is now in the warranty of thier machines, and the customer must check the machines parts so that failure doesn’t damage other parts/personnel. The technicians and us engineers were always the go between the customer and our sales. It was not a pleasant experience and am glad I am retired. Please note I do not wish to say or imply any negative comment on this product, only addressing a problem with aluminum, saltwater (and solvents/cleaners) and electrolysis.

You may try an anode such as zinc to slow this process (available at any good marine boat store). This may be a option in areas that have problems.

I hope this helps

DJ – Great point. Tell me, would anodized aluminum be a problem as well?

Jayson – The dealership is just trying to sell you something – there’s no reason that one lift kit would be more warrantable than another. I’ve never heard anything bad about the RevTech kit, and the fact that the dealership prefers it is a compliment. Still, don’t feel like you have to buy that brand just because the dealer wants you to. Dealers will warranty the truck regardless of the kit (so long as the kit isn’t the cause of the warranty problems).

It looks like alot of work and thought went into this. Including the angle of the back blocks. I commend you for this. There is just one thing. You have an aluminum piece against a steel piece. This under alot of vibration and movement. This may be fine for mudrunners in the south, but lets throw in winters in the northeast or the surf fisherman where this part is subject to saltwater. No matter what you do you will not be able to prevent the penetration of saltwater between aluminum and steel. This is going to create major electrolysis. The aluminum part will be eaten away (especially between the two part that you won’t see). I have had more experience with this and trying to solve this with machines in the marine industry. It can happen slow or extremely fast depending on conditions. If any doubt, look at the local saltwater marina, at the boatowners who thought they were saving money by not replacing thier zincs. I hope you thought about this in your warranty. I know you have done alot of work in this, and only wish to prevent heartache with you and your customers.

I like what I am reading about the Low Range and the Toytec 3″ leveling kits. I just purchased a 2010 crewmax and want a leveling kit on there. The dealership assessory department only wants to instal the Revtech 2.5″ kit for whatever reason. I believe the kit does uses 6061 spacers. However I was unable to find out if there is any differential drop spacer in the kit. Does anyone know anything good or bad about the 2.5 Revtech. Id rather go with the kits mentioned in this forum but want to maintain my warrenty (my dealership = revtech only. Any thoughts?
