Space Matters: The James Webb Space Telescope

Welcome back to the blog!

For this entry of Space Matters, we're taking a look at an incredible project years in the making, the James Webb Space Telescope. Scheduled for launch in late 2018, Webb will reveal a universe we have never seen before and is poised to answer questions that have intrigued us for thousands of years: How did the universe begin? Where did we come from? Are we alone?

In development since 1996, the project represents an international collaboration of the European Space Agency, Canadian Space Agency and teamwork from members of other countries although led by NASA in the U.S.A. The telescope is named after James E. Webb, the second administrator of NASA, who played an integral role in the Apollo program. The James Webb Space Telescope was originally called the "Next Generation Space Telescope," or NGST. It was called "Next Generation" because Webb will build on and continue the science exploration started by the on-orbit work of the Hubble Space Telescope. Discoveries by Hubble and other telescopes have caused a revolution in astronomy and have raised new questions that require a new, improved, and more powerful orbital space telescope.

JWST will offer unprecedented resolution and sensitivity into the infrared wavelengths of light. While the Hubble Space Telescope has a 2.4-meter (7.9 ft) diameter mirror, the JWST features a larger segmented gold 6.5-meter-diameter (21 ft 4 in) primary mirror and will be located near the Earth–Sun L2 point. To see deeply into the infrared a large multi-layer sunshield will keep its mirror and four science instruments below 50 K (-220 °C; -370 °F). JWST's capabilities will enable a broad range of investigations across the fields of astronomy. One particular goal involves observing some of the most distant events and objects in the universe, such as the formation of the first galaxies. In the deep dark of outer space these types of targets are beyond the reach of current ground and space-based instruments. Ground telescopes and unshielded orbital telescopes glow themselves, from the internal heat within the instruments. Another goal is furthering our understanding of the formation of stars and planets. This will include direct imaging of supernovas, extra-solar objects, such as exoplanets - the worlds around other stars, that could be brought to life with vivid detail through the imagery provided by The James Webb Space Telescope.

NASA has described JWST as the scientific successor of the Hubble Space Telescope, but not a replacement, because the capabilities are not identical and the Hubble will not be taken offline. JWST has an objective lens large enough to see high-redshift objects, typically both older and farther away than previous instruments could assess. This radical design for JWST will put it beyond the capabilities of all other telescopes currently in operation.

We'll be keeping an eye on the development and launching of this monumental project and you should too, as we seek to expand our knowledge of the cosmos collectively as a species. We'll have more to come, thanks for reading!

Anodized Trailer Blocks Now Available

Welcome back to the Trailer Blocks Blog.

We here at Trailer Blocks have an exciting announcement we’d like to share with you today. As part of our on-going efforts to better serve the trailer performance community, we have added Type II anodized Trailer Blocks as an optional feature for our lift/lowering kits. Adding this surface technology to your blocks will help you get the most out of your installation in all sorts of environments, such as harsh winter roads and boating/marine applications.

"This option is selected using the second drop-down on the product pages."

“Anodizing” refers to a basic electrochemical process performed on the metal which induces a protective layer of aluminum oxide on the lift/lowering blocks. The aluminum oxide coating is not painted on, but fully integrated into the metal and as such; it will not chip or peel off over time. This oxidized layer greatly increases the block surface’s resistance to corrosion, as well as offering a more durable finish to withstand harsh environmental conditions on the road. It is worth pointing out that while anodizing does provide additional exterior protection for our lift blocks, it does not increase their strength or weight rating. This option is designed to provide better resistance to dissimilar metal corrosion electrically isolating the Trailer Block from the steel it is in contact with on the axle and leaf spring.

We're excited to offer you another high-quality solution to lift or lower your trailers. If you have any questions about our anodized blocks, please contact us via email, social media or leave a comment below and we’ll be happy to help you out.

Thanks for reading!

Trailer Tech: Spring has Sprung Checklist

Welcome back to Trailer Tech!

The snow is melting and the days are getting warmer. Spring is here and it’s time to get back on the road. With the weather improving, now is the perfect time to perform some maintenance and any necessary modifications to your trailer to get ready for spring and summer road trips. During our performance voyages and other road trips, we made some observations on the checks needed to keep our trailer running smoothly.


  • Begin with a basic visual check and make sure everything on your trailer is in good working order. An obvious tip perhaps, but it can be easy to not pay enough attention to this step. This includes anything that actuates or illuminates
  • Assess the general condition of the axle
    • Grease the axle bearing nipples or repack your bearings to keep them running cool and smooth. Check with your axle manufacturer for model specific maintenance requirements
    • Check for wear and proper impedance on electric brake magnets. Magnets that test outside of the manufacturer specified impedance should be replaced
    • Remember that you will need marine-grade grease for boat trailers backing in and out of the water up and down boat ramps
    • Check brake hydraulics (if equipped) for leaks. Change the hydraulic fluid per the manufacturer's recommended schedule. Ensure the parking brake and breakaway cables are not frayed or properly connected
    • Check brakes for uneven wear or scoring, proper mounting and ensure proper actuation. If the brake pads or shoes are approaching the linings, they should be replaced
  • Check the lug nut torque and ensure that your wheels are not falling off! Apply a thin layer of anti-seize to the studs
    • Check the tires for bulges, cuts, nails and heavy/uneven wear
    • Tire pressure checks reduce tire wear and the use of nitrogen will result in lessened loss of pressure over time

  • Prevent corrosion with rust inhibitor products and touch up paint. Remember that a little bit goes a long way! Thick applications of rocker guard, rust inhibitor, undercoat, anti-seize and paint allows moisture to build up over time and rust the underlying component.


    • Water has the unique characteristic of expanding when changing from a liquid to a solid state, and during a freeze thaw cycle, moisture in between the leaves in a leaf spring pack can loosen and shift the leaves. Even if your trailer sat idle for most of the winter, it is important to check that the leaf pack is tight and straight and that the spring clips are free of rust and tight.
    • Some springs require additional attention during maintenance in the shackle and bushing departments due to comparatively higher complexity when mounting. Many modern double eye springs use a nylon, bronze, or polyurethane bushing. Worn bushings will appear frayed or cracked towards the outer edges and become worn down and thin towards the center, developing groves from wear. Bronze bushings require wet bolts that need to be greased.
    • Applying a thin layer of grease anywhere there is contact between shackle straps and spring hangers ensures the spring can flex freely without binding.
    • Check spring seats shackle straps and hangers for cracks in the welds that secure them to the frame or axle. Check for bends and deformations and excessive wear around bolt holes. Replace as necessary and prevent corrosion with rust inhibitor products and touch up paint.
    • Ensure shock absorbers provide adequate resistance, and replace if they feel loose or leaky. Ensure shock absorber and rubberized equalizer bushings are pliable and are not cracked or hard.


    • During installation, U-bolts should be torqued down only once. Reusing them reduces clamping force by 55%.
    • Torque should be checked/re-checked after road-testing and some use. If your leaf spring pack, leaves, or Trailer Blocks have shifted, your U-bolt torque may be incorrect and should be checked.
    • Always ensure they are SAE-Grade 8 with rolled thread
    • Prevent corrosion with a thin layer of anti-seize on U-bolt threads. This can help to facilitate re-torque. Use a thin application of rust inhibitor on tie plates and U-bolt arms as needed.

      We hope the tips outlined thus far have been helpful in guiding your seasonal checks in a effective way. It is important to remember that your trailer may have special or varying equipment that needs additional maintenance and checking. Always consult your owner’s manual for exacting recommendations. If you are not mechanically inclined or equipped to carry out the seasonal checks you should consult a qualified mechanic with experience working on trailers.

      If you feel we’ve missed anything or would like to add to the discussion, please leave a comment below or contact us at contact@trailerblocks.com if you have a question for us specifically.

      Thanks for reading.
