The threaded shock absorbers are the final step in the build and as you'd expect if you've read this far into the review - are very high quality. Two different pistons are included in the kit, a two-hole and three-hole piston - the manual directs to use the two-hole all round but I was now following the setup used by one of the UK team drivers the weekend previously to good effect - so opted for the three-hole in the rear, drilled out to a Losi 'Blue' size (close to 1.4mm).
The pistons appear to be the same diameter as Associated pistons - and whilst I didn't measure the damper bodies themselves I'd assume they were a similar size to the AE units. The pistons do away with pesky E-Clips used on most other dampers - instead opting for a small screw to secure the piston to the shock shaft. After experiencing a failure on an 8th scale - I know how vital it is to threadlock this tiny screw! (I sound so confident here - read the DEX410 race report later in the review for what happens if you don't put enough threadlock on!) The seals and guides insert into the damper bodies from below and are capped with a red alloy bottom cap - a nice feature of the DEX410 dampers is the bevel on the bottom of the shock shafts - it makes inserting the shafts easy, with very little risk of damaging the seals. Ok - it might not sound like something you'd get all excited about, but it's attention to detail like this that makes this buggy what it is.
2 and 3 hole pistons are included
Pistons attach with screws - THREADLOCK!
I drilled the rear pistons to Losi Blue size - ~1.4mm x 3 holes
Smooth bevel makes tearing seals much less of a problem - I love this.
Bleeding the shocks
Rubber boots slip over the bottom of the dampers
I ask myself at this point - is there actually threadlock on those screws or did I assemble them for photos and then forget? hmmmmmmmmmmm.
Top and bottom 'guides' lock into the damper body and bottom cap respectively to ensure a perfectly aligned shaft.
The top caps feel a little loose going on but tighten up quickly and feel secure. They feature a bleed screw so getting the right air-oil/ratio is pretty easy and painless.
To finish things off rubber boots are supplied with the dampers - again, these are optional and the dampers do look so nice without them, but we chose to fit them since we love the idea of less maintenance. The boots slip over the shaft and wrap tightly around the bottom cap.
Team Durango have a massive range of springs available for the car - 8 front and 8 rear weights. The springs supplied in the kit are dark-blue front, which is 3rd from hardest, and sky-blue rear which is 4th from hardest - so pretty much in the middle of the range.
The quick-tune shock mounts are super strong and make changing locations easy.
The dampers mount up with quick-change screws for the towers. These look incredibly strong and have great support against the shock towers. A nut secures the screws to the tower from behind - removing the nut allows the screw to be pushed into a different mounting location quickly and easily. All this without having to remove the damper and various spacers. Steel balls are used top and bottom for the shock to pivot on - again this means the screws/nuts can be clamped down hard without binding the damper movement.
