Frequently Asked Questions

Yes, All of our Spider Rock Guards and Rock Crushers are supplied with Stainless Steel mounting hardware.

.250, one quarter on an inch. When designing it, we wanted to keep the covers outer structure as close to the axle as possible. The cover is a full .250 thick that is why it protrudes this amount, it should not interfere with most steering applications.

All of our Spider Rock Guards and Rock Crushes are Blanchard ground at our facility. Most have a TIR (total indicator reading) of no more than .001, that is flatter than most axle housing surfaces.

Because if you have been rock crawling for any length of time without a Spider Rock Guard or Rock Crusher cover you may have twisted your axle (we have encountered many). If it is twisted you will not pull our .500 flange even slightly against a twisted housing, the result will be a leaking cover. Instead we recommend using a high quality RTV instead.

No modifications to our Spider® Rock Guard or to any component on your vehicle is necessary when using either our Spider Rock Guard or Rock Crusher Cover. In fact we have seen individuals at four wheel drive events install our Spider Rock Guards without even removing the cover and draining the fluid. We recommend changing the fluid at the time of installation but this just illustrates how easy installing our products are

No, We now have over 50 different colors, we do not keep over 50 different colors of each of our Spider Rock Guards (40 different models) on the shelves. We would not enough warehouse space, everything is on our shelves bare (bare metal). When you order a custom color allow 4-6 business days before shipping.

Yes, we have over 45 custom powder colors now and we do not apply each of them everyday. When we first started to do all of our powder coating in house we would switch from Black Hammertone to colors every 3 days. But now with so many color choices we actually apply colors more than the standard Black Hammertone, as a result customers will even have to wait for Black Hammertone. Even with the wait our prices and lead time cannot be beat. An average Powder Coating Shop cost for one (1) Spider Rock Guard in our standard Hammertone Black is $33-$45 and lead time is 2-3 weeks. Ours is $15 and 4-6 business days.

It may or it may not. Our Spider Rock Guards for Aluminum covers are only guaranteed to fit our PCP Aluminum covers. The casting thickness and drain plug location varies tremendously from manufacture to manufacture. Although many customers have said our covers are exact matches (size and dimensions) for some of the other aftermarket covers, we cannot guarantee it will fit.

We manufacture more Spider Rock Guards than Rock Crushers, do we manufacture a Spider Rock Guard for your application? If not you are still in luck, we can manufacture a Rock Crusher cover complete with integrated drain plug, dip stick, internal magnets, powder coated inside and out and all NMSS fasteners for $225.99.
