GTR springs are offered in different rates to tune your suspension performance or compensate for lighter or heavier vehicle configurations. *Weight comparison based on Traxxas #3655X. Shock springs for 1/10 scale long GTR shocks use high-quality spring steel with a durable white powder-coated finish. The upper hinge pin hole of the rear axle carriers cannot be used (not a stock location for the Slash 4×4) due to strengthening designs that reduce the clearance around the rear axle. Two packages will be needed to complete one truck.

RPM arms are sold in sets of 1 – left and 1 – right A-arm in each package. RPM A-arms will not fit ST versions of the Rally (please see RPM #73362). Tech Notes: Replaces stock Traxxas #3655R & #3655X. High Torque 400 with a brushless motor inside. High Torque 330 with coreless motor, and the 400 oz.-in. For greater steering authority and durability, Traxxas offers three metal-gear servo options: the 125 oz.-in 2075X, the 330 oz.-in. We proudly stand behind our products! Designed, manufactured and produced right here in southern California in the USA! The Slash 4X4’s 2056 servo is equipped with plastic gears and steers with 80 ounce-inches of torque. The front differential housing was replaced due to the hex screws being stripped. RPM A-arms are molded in our trademark blend of incredibly durable nylons and are backed by an industry leading warranty. The Slash Ultimate 4X4 was rebuilt from the ground up. Additionally, you now have the option of a bit of color with black, blue, green and red to choose from. Friend got the ultimate and I got just the VXL. RPM A-arms carry over our traditional look with our 30 degree leading and trailing edges, and huge bosses for the shocks and sway bar mounts. Only downfall of the Ultimate for me is the LCG Chasis, just not for me. We can’t forget about how much better aesthetically the RPM versions look either. Quick video going over some suspension tuning I did to my Slashs to make these trucks more stable without affecting the plushness of the suspension too much. As a bonus, we cut 6.5 grams of weight off of each A-arm*! That’s a total loss of just under one ounce of weight simply by replacing your stock A-arms with the RPM versions!

We eliminated the slop in the suspension system, tightening the tolerances around the hinge pins, reduced the fore and aft movement of the A-arms at both the inner hinge pin and at the axle carriers by better than 90% and improved the durability dramatically (they’re made by RPM, enough said). RPM A-arms for the Traxxas Slash 4×4, Rustler 4×4, Hoss 4×4 & Stampede 4×4 are everything you’ve come to expect from RPM and more! Take a look at everything we’ve done:
