Hi everyone! We're sliding into the end of 2025 with the biggest Black Friday sale we've ever had! This year we're doing things a little bit differently. The more you buy, the more you save! So if you've been planning on picking up some MPP parts, you won't see discounts like this again for a...

We love our R1T so much, and it's been a lot of fun to develop new stuff for. Among our favorites: our new brake lines! We partnered with HEL Performance again (They also help make our Tesla brake lines) to deliver a truly stainless steel brake line - including the fittings and bolts, which are...

The R1T is a platform we quickly fell in love with, and wanted to preserve as much of its great styling as possible. The door sills of any truck are often the most worn out paint surface early on, as they're subject to our constant foot traffic and the debris that comes with it. The idea behind...

Hey everyone! We have a handful of upcoming releases for the R1T, but we wanted to see what some fellow passionate R1T owners thought about addressing any shortcomings the truck might have. Some of you hit off-roading trails with these things, and we know a few of you have been doing drag...

Hi Everyone! I hope you're all doing great as summer comes to a close. We've been comparing our Rivian and Cybertruck back to back and one annoyance has been the unit conversions - as Rivian uses distance/kWh and Tesla uses wh/distance. Between that and converting between miles and km, it got a...

Hey everyone, I'm going to make a little towing journal here to document our current efficiency with different configurations so that we can compare in the future. The goal long term is to modify our 26' Featherlite trailer to be more aerodynamic. CFD suggests a significant reduction in drag...

Hey Everyone, We finally got out to my friend's farm to test our R1T against the Cybertruck, as well as to compare the two vehicles against his new Raptor R. Scotty's farm is an awesome place for us older kids to play, and while we were really expecting the Rivian to be far and away better in...

Hi Everyone! We’re thrilled to announce our brand-new Rivian wheels! We spent months on this wheel design in-house at MPP – aiming for something motorsport inspired, aerodynamic, functional, and clean. We really love the way these Rivian wheels came out, and hope you do too! These wheels have...

Hi Everyone, I hope this is the right place to post this. As we shared on our Instagram and a little bit in the MPP section on the forum, we've been working on a unique air suspension height adjustment solution for these trucks. If you don't know about us or you haven't heard the MPP name, I...

Hi Everyone, With Tesla's opening of supercharger access for Rivians opening up on the 18th, we were eager to get to a supercharger and experience the process. The pain here in Canada of Level 3 chargers is unberaable, and you'll see in the video we have some rather pointed words for the charge...
