2004-10 Toyota Sienna Strut & Spring Assembly Pair - 1ASSP00846

In the past, replacing struts required specialized tools to compress, remove and transfer the old spring and mount.  Pre-assembled with all new parts, our complete strut and spring assemblies make this job much quicker and easier for the do-it-yourself mechanic.

Each complete strut & spring assembly contains:

  • Upper Strut Mount
  • Strut Bearing
  • Coil Spring
  • Boot & Bumper Kit
  • Gas-charged Strut 

Pre-assembled, loaded strut & spring assemblies allow for a quicker, safer install than replacing with just bare struts.  No spring compressor required! 

Trouble-Free Install

Trouble-free install includes the matched parts needed to get the job done. New mounts, bearings, springs and hardware will provide a better ride for your vehicle and save you time from not having to do the job again because a used part failed afterwards.

Matched Parts

When you buy the kit pre-built by us, you can be sure that the parts are matched for optimum performance.  Not all shocks and struts are manufactured the same, so mixing and matching can result in fit issues and potentially decrease the life of the parts.

Saves Time & Money

When you buy one of our kits, you not only save money over buying the parts individually, but you also save time having to search for all of the different parts that are correct for your vehicle (because we did it for you!)

Lifetime Warranty

This item is backed by a Limited Lifetime Warranty. In the event this item should fail due to manufacturing defects during intended use, we will exchange the part free of charge (excludes shipping charges) for the original purchaser. Please keep your invoice for proof of this warranty.

Perfect fit
These installed like a charm. the product itself was quite a bit lighter in weight than the originals that i pulled out. Not sure if it due to better design or cheaper quality. So far it is working great. My suggestion is that if you are replacing the strut/spring assembly, to also invest in new sway bar links. I had to cut both mine off due to rust and corrosion stripping out the allen head.

What size are the three nuts on the top mount assembly?
Walt L on May 21, 2018
BEST ANSWER: I don't have the exact measurements. Our parts are designed to be exact replacements for what came with the vehicle, so as long as your year, make, and model match up with our listing, these will definitely fit and function just like the original. Please let us know if you have any other questions.
What is the difference, and how does one tell which assembly if for the right front, which is for the left front?
Walt L on May 18, 2018
BEST ANSWER: If you purchased these items from us there will be part numbers that correspond to the packing slip that came with the shipment. The parts will also match the items in the vehicle. Thanks!
What brand of strut is this?
